Staff Engineering and the CPTO — Getting the Most From Your Principal Engineers

There’s a staffing pattern I’ve seen in enough organizations to call it a norm: the staff engineer or principal engineer who has remarkable technical judgment, real cross-functional influence, and genuinely nothing to do at the level where their judgment would matter most. They’re writing design documents for their team’s work, reviewing architecture decisions that are a layer or two below their actual capability, and sitting out the conversations where the most consequential product-engineering tradeoffs are being made.

This is partly a structural problem and partly a relationship problem. On the structural side, most orgs don’t have a clear mechanism for pulling staff engineers into strategic decisions. The management chain owns the escalation path. The product roadmap process is run by PMs. The architecture review board — if it exists — often functions as a veto mechanism rather than a design input mechanism. Staff engineers who care about participating in the decisions that shape their work have to create their own influence through informal relationships, which rewards the politically savvy and sidelines the technically focused.

On the relationship side, many CPTOs don’t have a direct working relationship with their staff and principal engineers. They have a relationship with their engineering leaders, who have a relationship with the staff engineers. That indirection means the CPTO doesn’t have access to the ground-level technical judgment that the staff engineers carry, and the staff engineers don’t have visibility into the strategic context that would let them align their technical direction with the business.

The leverage point

The highest-leverage change I’ve made in the organizations where I’ve worked well with staff engineers is direct access. Not bypassing the engineering managers — that creates its own problems. But creating explicit channels where the most senior technical contributors are in the room for the decisions that shape their work environment.

In practice, this means including staff engineers in the technical roadmap process as contributors rather than reviewers. It means bringing them into the product-engineering alignment conversations where the real tradeoffs get made. It means, occasionally, asking a principal engineer to lead an architecture review for a major initiative rather than staffing it down through the management chain.

The returns on this are asymmetric. Staff engineers who feel their judgment is being used tend to stay. They tend to bring problems they see early rather than waiting until they’re unavoidable. They tend to act as informal leaders who carry the technical culture in ways that managers can’t, because their influence is based on technical respect rather than positional authority. When you’ve got a staff engineer who is genuinely invested in the organization’s technical direction, that person does more to maintain engineering standards than any process you could design.

The conversation you need to have

The most useful thing a CPTO can do with their senior technical contributors is have an honest conversation about what those engineers think is wrong with the system. Not what they’re working on. Not what their team needs. What they think is fundamentally misaligned between how the organization makes technical decisions and what the technical work actually requires.

This conversation is uncomfortable because the answers are often critical of things the CPTO owns. The roadmap process is too quarterly, too committed, too resistant to the technical discoveries that happen during implementation. The incident response process doesn’t close the loop back to the product decisions that created the conditions for incidents. The build-vs-buy calculus on a major dependency was wrong and everyone knows it but nobody wants to say so formally.

Staff engineers have opinions about all of this. In my experience, they’re usually right, often more precisely right than anyone else in the building, because they’re close enough to the technical reality to have seen the evidence and senior enough to understand the strategic context. The question is whether the CPTO has created the conditions where they’ll share those opinions honestly. If the answer is no — if your staff engineers are polite and deferential and never say anything that makes you uncomfortable — that’s a problem worth investigating.
