Senior Staff Full Stack Engineer

Some of the most important problems at Strava don't belong to any one team. They're cross-stack, ambiguous, and high-stakes, and they need someone who can walk in, figure out what's actually going wrong, and drive the fix. This role exists to be that person. You'll report directly to a Senior Director of Product Engineering and join a small bench of exceptional individual contributors deployed against Strava's riskiest and least-understood technical problems. You'll think across client and server at the same time, move between initiatives as priorities shift, and bridge what's on fire today with what we need to build next. You'll also help drive change in newly integrated parts of the business, including our work with Runna.

Responsibilities

Drop into ambiguous, cross-stack problems and diagnose what's actually happening before prescribing a fix; Reason fluently across client and server systems to unblock high-priority product initiatives; Drive measurable impact on critical bets, starting with initiatives in our organic growth and subscriber value areas; Act as a trusted agent of change inside teams and parts of the business you don't own; Partner with leadership and senior ICs to surface recurring product and technical opportunities worth attacking proactively; Set technical direction and bring people with you on the highest-risk work in the company

Requirements

Genuine full-stack range, with the ability to operate in systems you didn't build; A track record of entering unscoped, cross-team technical problems and driving them to resolution; The ability to influence and drive change without formal authority; Senior technical judgment: you set direction, earn the trust of leadership, and operate well in ambiguity

Nice to have

Experience navigating a recently acquired or integrated organization is a plus; A prior tiger-team, fixer, or SWAT-style role at scale is a plus
