In dual-track career ladders — the structure used by most Big Tech companies and larger scaleups — the staff+ engineering rung is intentionally placed at the *same career level* as engineering manager (EM) and senior product manager (PM). This is not symbolic. It is a structural claim that the staff+ engineer is the *peer* of the EM and PM, not their subordinate technical resource. Uber's principal engineer (L7) sits at the same level as director of engineering (also L7), and is expected to partner directly with directors of engineering and product. The expectation is asymmetric in an important way: the partnership is rarely written down and almost never assigned. It must be initiated and sustained by the staff+ engineer. The EM/PM side of the table generally has explicit operating cadences (1:1s, planning rituals, OKR reviews) that they run by default. The staff+ engineer, lacking direct reports and explicit ritual structure, has to *manufacture* the partnership — show up to planning conversations they weren't invited to, write the technical strategy doc nobody asked for, build the trust capital that lets them disagree with the EM in front of the team without it being insubordination. The staff+ engineer who waits to be invited into the partnership stays at senior. The one who behaves as a peer — and is *correct* often enough that EMs and PMs come to expect their input — becomes the role model the title implies. ## Key Insight Dual-track ladders place staff+ engineers and EMs/PMs at peer career levels, but the partnership behavior is structurally one-sided: EMs and PMs run the rituals; staff+ engineers must invest the unpaid coordination labor that makes the peer relationship real. The promotion to staff+ does not create the partnership — performing the partnership is what the promotion was rewarding. ## Connections - [[Three Lenses for Evaluating Staff+ Engineering Titles]] — sibling note from the same source - [[Staff Engineer Title-Scope Misalignment]] — what happens when companies issue the title without funding the partnership - [[Career Edges Over Career Ladders]] - [[Legible Impact Over Silent Execution]]
