Why This Post Exists
The first post in this series established two foundational ideas: scaling as a Principal Engineer is a step-function change (not a gradient), and your voice carries outsized weight that you need to actively manage. But understanding that the scope changed doesn’t tell you how to operate at the new scope. Knowing you need 10x leverage doesn’t tell you where to find it.
This post is about the operational side of that shift. Specifically, it’s about a pattern the Senior PE I spoke with described as “borrowing superpowers” — observing how adjacent roles create leverage, and adapting those patterns to the PE context. The insight isn’t that PEs should become managers or TPMs. It’s that managers and TPMs have solved a problem that most PEs haven’t even recognized they have: how to create impact at scale without doing the work yourself.
If the first post was about changing your mental model, this one is about changing your operating model.
The Misconception: Technical Authority Is Your Primary Lever
Ask most Principal Engineers what their leverage is, and the answer comes quickly: technical expertise. Deep knowledge. The ability to see around corners architecturally. Being the person who can look at a system design and spot the flaw that would have caused a high severity production incident six months from now.
And that’s real. That expertise is what earned you the role. It’s why people seek you out for design reviews. It’s why your opinion carries weight in architecture discussions. It’s why, as we discussed in the first post, your voice has a megaphone attached to it.
But here’s the problem: technical authority is a direct lever. It works when you’re in the room. It works when you’re reviewing the document. It works when you’re asking the question that nobody else thought to ask. The moment you leave the room, the lever stops working. The next design review happens without you. The next architectural decision gets made by a team you’ve never met. The next production system gets built by engineers who don’t know your opinion on the tradeoffs involved.
When your scope was 50 engineers, direct leverage was sufficient. You could be in enough rooms, review enough designs, and have enough one-on-ones to personally influence most of the consequential technical decisions. At 500 to 5,000 engineers, that model collapses. You can’t be in every room. You can’t review every design. And if your impact depends on your physical or virtual presence in a conversation, you’ve already hit the ceiling.
This is not a time management problem. It is a leverage problem. And the solution doesn’t come from getting better at being a technical authority. It comes from building systems that carry your technical judgment into contexts where you’ll never be personally present.
Mental model: The Principal Engineers who scale effectively don’t just have good judgment. They encode good judgment into mechanisms—processes, frameworks, forums, artifacts—that operate independently of their presence. The shift isn’t from doing technical work to doing non-technical work. It’s from direct influence to systemic influence.
The Superpowers You’re Not Using
Here’s something that might surprise you: the two roles in engineering organizations that have most thoroughly solved the “influence without presence” problem are managers and Technical Program Managers (TPMs). And most PEs have never seriously studied how either group operates.
This isn’t about career envy or role confusion. It’s about recognizing that these roles have developed specific capabilities that PEs need at scale—and that borrowing those capabilities doesn’t make you less of an engineer. It makes you a more effective one.
What Managers Know That You Don’t
Managers are, by the nature of their job, multipliers. They’re expected to create impact through others. And they have a lever that PEs don’t: positional authority. When a manager says “we need to prioritize this,” there’s organizational weight behind that statement that comes from the reporting structure. People listen partly because the manager has good judgment, but also because the manager has the organizational authority to set direction.
As Principal Engineers, we don’t have that lever. Nobody reports to us. We can’t direct someone’s work, set their priorities, or make organizational decisions about how teams are structured. And this is by design—the PE role is explicitly an individual contributor track.
But positional authority is only one of the tools managers use. Watch how effective engineering managers actually operate, and you’ll notice something: the best ones don’t rely heavily on positional authority either. They create alignment systems. They build shared understanding of priorities so that teams make good decisions autonomously. They participate in talent reviews and organizational planning forums that give them visibility into what’s happening across the organization. They create feedback loops that surface problems early. They establish norms and expectations that persist even when they’re not watching.
These are the patterns worth borrowing. Not the positional authority—you don’t have it and you don’t need it. But the systems thinking about how to create alignment at scale. The understanding of how organizational forums work and how to use them. The recognition that being included in talent reviews and technical assessments—which many PEs are, even as individual contributors—isn’t a bureaucratic obligation. It’s a strategic lever that gives you visibility and influence far beyond your immediate scope.
The Senior PE I spoke with made this point directly: “We benefit from the respect that the Principal Engineering community has earned. Our titles do reflect organizational weight—we’re included in talent reviews and tech assessments even though we’re individual contributors. That inclusion matters. It gives us a seat at tables where decisions are made.” Most PEs treat these forums as overhead. The ones who scale treat them as infrastructure.
What TPMs Know That You Don’t
The Senior PE mentioned that he gravitates toward TPM-like work—not because he particularly enjoys it, but because it happens to be something he’s good at, and because TPMs have a superpower that’s directly applicable to how PEs should think about scaling.
That superpower: TPMs create and manage mechanisms to get things done without positional authority. They don’t have direct reports. They don’t have organizational leverage in the traditional sense. But effective TPMs are extraordinarily good at creating structured processes and systems that enable work to happen across organizational boundaries.
Think about what TPMs actually build: project tracking systems, cross-team collaboration forums, decision-making frameworks, escalation paths, communication cadences. If you’ve ever dismissed these as “just process” or “bureaucratic overhead,” you’ve missed the point. These are leverage tools. They’re mechanisms that allow coordination to happen at scale without requiring any single person to be present in every conversation.
And they work because people trust that the mechanisms serve a real purpose. Not because the TPM has authority over anyone, but because the mechanism itself has earned credibility through consistent usefulness.
As PEs, we can build the same kind of mechanisms, tuned to our domain - Architecture review processes; Technical decision frameworks; Documentation standards; Cross-team knowledge-sharing forums; Design principle repositories. These aren’t administrative tasks. They’re the infrastructure through which your technical judgment reaches the 500 or 5,000 engineers you’ll never personally interact with.
Here’s the contrast that makes this concrete:
DIRECT LEVERAGE (doesn't scale):
┌───────────────┐ ┌───────────┐
│ PE reviews │────▶│ 1 design │
│ a design doc │ │ improves │
└───────────────┘ └───────────┘
Time cost: 2-4 hours
Impact radius: 1 team, 1 decision
SYSTEMIC LEVERAGE (scales):
┌───────────────────┐ ┌──────────────────────────────┐
│ PE creates a │────▶│ Every design doc across the │
│ decision-record │ │ org includes alternatives │
│ template with │ │ considered, tradeoffs made, │
│ required fields │ │ and failure modes analyzed │
└───────────────────┘ └──────────────────────────────┘
Time cost: 8-16 hours (once)
Impact radius: all teams, all decisions, ongoing
The PE in the first row is doing important work. The PE in the second row is doing leveraged work. Both matter, but only the second one scales to Senior PE scope.
Building Mechanisms Without Asking Permission
Understanding that mechanisms are your primary lever is one thing. Actually building them is where most PEs get stuck. And they get stuck for a predictable reason: they wait for permission.
This instinct makes sense if you think about it. Engineers are trained to operate within defined systems. We work within architectures, follow processes, use tools that someone else set up. When we want to change something systemic—a review process, a communication forum, a decision framework—our instinct is to propose it, get buy-in, navigate the organizational approval chain, and then implement it once everyone agrees.
By the time that process completes, the window of opportunity has often closed. Or the mechanism has been committee’d into something so watered down that it doesn’t actually solve the problem it was designed to solve.
The Senior PE shared a story that illustrates the alternative approach. When his organization went through a major restructuring—splitting into two separate orgs—the existing PE community was at risk of getting diluted. The PE community in the new structure needed its own identity, its own coordination mechanisms, and its own forums for making technical decisions. Without that, consequential architectural choices would be made inconsistently across teams, and the PEs who should have been coordinating would be isolated in their respective corners of the org.
So the Senior PE started a council. A small group of Principal Engineers who had the technical standing and organizational context to make certain cross-cutting decisions. He created a regular forum where these PEs would discuss architectural direction, coordinate on shared technical problems, and establish standards that would apply across the organization.
Here’s the important part: he didn’t have permission to do any of this. He didn’t submit a proposal. He didn’t ask his leadership chain whether it was okay to create a PE council. He didn’t wait for someone else to notice the coordination gap and assign someone to fix it. He just built the thing and waited for someone to object.
No one did. What happened instead was that people started thanking him. Engineers and managers were grateful that someone had created a forum where decisions could be made efficiently. Where the PE community could coordinate rather than working in isolation. Where technical direction could be set with input from the people who had the deepest understanding of the systems involved.
At that point, he thought, “Okay, let’s keep doing it.” And the council became an established mechanism that people now rely on.
Why This Works (And When It Doesn’t)
This approach works because of a dynamic that most PEs underestimate: in large organizations, there is usually more demand for coordination mechanisms than there is supply of people willing to create them. Most coordination problems persist not because anyone opposes solving them, but because nobody takes the initiative to build the solution. The friction isn’t resistance—it’s inertia.
When you build a mechanism that clearly solves a real problem, adoption tends to happen naturally. People use it because it makes their lives easier, not because someone told them to. And leadership tends to support it because it reduces chaos and improves decision quality. The Senior PE’s council succeeded not because he had authority to mandate it, but because it filled a genuine vacuum.
That said, this approach has boundaries. There are situations where building without permission can backfire:
When the mechanism steps on someone’s existing authority. If there’s already a team or a leader who considers coordination in that space to be their responsibility, creating a parallel mechanism can feel like an encroachment rather than a contribution. The fix isn’t to avoid building—it’s to build with those people, not around them.
When the mechanism adds burden without clear value. If people experience your mechanism as “yet another meeting” or “yet another document to fill out,” it will die from neglect or breed resentment. The test is simple: does this mechanism make it easier for people to do the right thing, or does it add friction? If it adds friction, it’s not a mechanism—it’s bureaucracy.
When you’re solving a problem that doesn’t actually exist. Sometimes the coordination gap you’ve identified isn’t felt by anyone else. Before building, validate that others experience the problem. You don’t need a formal survey—a few conversations with the engineers and managers who would use the mechanism will tell you whether the need is real.
The rule of thumb the Senior PE offered: start small, build something that clearly adds value, and be willing to shut it down if it doesn’t work. The organizational cost of a failed lightweight experiment is negligible. The organizational cost of a coordination vacuum that persists for months because nobody was willing to act without permission is substantial.
Your Unique Leverage: What Managers and TPMs Can’t Do
Borrowing from managers and TPMs is essential, but it’s also important to understand what makes PE leverage distinct. You’re not a manager without direct reports. You’re not a TPM who happens to know how to code. You have a form of influence that neither role can replicate.
Your leverage is trust built through demonstrated competence. When you speak about technical matters in your domain, people listen because they know you’ve built systems, debugged production incidents at 3 AM, made hard tradeoffs under real constraints, and lived with the consequences. That credibility isn’t granted by a title or an org chart. It’s earned through a track record of being right about things that are hard to be right about.
This means your mechanisms carry a different kind of authority than a manager’s process or a TPM’s coordination structure. When a PE creates a technical decision framework, it’s not just a process artifact—it’s an encoding of how someone with deep systems experience thinks about tradeoffs. When a PE establishes architecture review standards, those standards carry the implicit endorsement of someone who knows what good architecture looks like because they’ve built it and maintained it and debugged it when it failed.
This is also why the Three-Position Framework from the first post matters so much in the context of mechanisms. The mechanisms you create should be grounded in your Position One expertise—the areas where you genuinely have deep, earned authority. A decision framework for distributed systems architecture, created by a PE who has spent a decade building distributed systems, carries inherent credibility. The same PE creating a mechanism for, say, product prioritization or team staffing would be operating in Position Three territory, and the mechanism would lack the earned authority that makes it trustworthy.
The combination is what makes PEs uniquely effective at scale: systemic leverage (borrowed from managers and TPMs) combined with earned technical credibility (your own). Neither alone is sufficient. Technical credibility without systemic leverage means you’re brilliant but limited to the rooms you’re in. Systemic leverage without technical credibility means you’re creating processes that people follow grudgingly rather than trust deeply.

Putting It Together: From Instinct to Operating Model
Let me make this concrete with a before-and-after that captures the shift this post is arguing for.
The PE operating on instinct gets pulled into a design review. The design has a subtle problem with how it handles failure modes in a distributed workflow. The PE catches it, explains the issue, suggests a better approach. The team fixes the design. Good outcome. Time cost: three hours for the review plus follow-up. Impact: one team, one design, one decision.
Two weeks later, a different team in a different part of the org ships a design with the exact same failure mode. The PE never saw that design. Nobody asked for a review. The problem goes to production and causes an incident.
The PE operating on mechanisms has the same instinct and the same expertise. But instead of stopping at the individual review, they recognize the pattern: this failure mode keeps showing up because teams don’t have a shared framework for thinking about failure handling in distributed workflows. So the PE writes a technical decision document—not a long architectural treatise, but a concise, opinionated guide to the three or four failure-handling patterns that apply in their domain, with clear guidance on when to use each one. They publish it to the PE community. They reference it in the next architecture review. They ask other PEs to reference it in their reviews.
Six months later, new designs in that organization routinely consider failure modes that teams used to miss. Not because the PE reviewed every design, but because the mechanism carried their judgment into dozens of design conversations they were never part of.
That’s the difference between direct leverage and systemic leverage. Same expertise. Same good judgment. Radically different impact radius.
The Real Shift
The Principal Engineers who successfully scale beyond their initial scope share a common trait: they stop thinking of themselves primarily as technical experts who happen to influence people, and start thinking of themselves as systems builders who happen to have deep technical expertise.
This is not a demotion of technical skill. It’s a recontextualization of it. Your technical expertise doesn’t become less important—it becomes the input to mechanisms rather than the output of your daily work. You still need to be deeply technical. You still need to review designs, debug hard problems, and make consequential architectural calls. But those activities shift from being the primary way you create impact to being the way you stay credible enough that your mechanisms carry weight.
The leverage equation for a Principal Engineer at scale is multiplicative: systemic leverage times technical credibility. If either term is zero, the product is zero. A PE who builds great mechanisms but has lost touch with the technical realities of the systems they influence will create processes that teams route around. A PE who maintains deep technical expertise but never builds mechanisms will be individually brilliant but organizationally limited.
If there’s one takeaway from this post, it’s this: the question to ask yourself isn’t “how can I apply my technical expertise to more things?” It’s “what mechanisms can I build that will apply my technical judgment to things I’ll never personally touch?” That’s the shift from direct leverage to systemic leverage. That’s how you operate at 10x to 100x scope without working 10x to 100x hours.
The next post in this series covers a specific and powerful form of mechanism: the artifacts, writing, and knowledge-sharing practices that scale your mentorship and establish your technical authority across organizational boundaries.
