Senior Product Engineer - US
Coefficient, San Mateo, CA +1
The role
We’re looking for experienced Product Engineers who operate with high agency, strong ownership, and deep curiosity.
This is not a scoped, ticket-driven role. You’ll work directly with the founders to define product direction, build core systems, and ship end-to-end experiences.
What you need
- Take full ownership of problems—from idea to production
- Are relentlessly curious and think from first principles
- Move quickly, make decisions, and iterate without perfect specs
- Care deeply about product quality, UX, and craft
- Thrive in ambiguity and low-structure environments
Technical expectations
- 6+ years of experience building production web applications
- Experience with modern web stacks (e.g. TypeScript, React, Next.js, or similar)
