dex - Staff Product Engineer

• Leading teams or entire product lines - You can take responsibility for driving delivery across a team or across an entire product line • Seeing good at scale, and early stage - you've moved fast in scrappy, early-stage environments, and seen what good looks like at scale • Independent delivery - You can own and ship end-to-end product slices with minimal supervision; your track record shows features that shipped, stuck, and scaled • Product trade-off judgment - you balance speed, quality, and user impact under ambiguity; you push back when something is underspecified and make pragmatic calls when it needs to ship • Reliability and API discipline - you handle data integrity, error paths, idempotence, and API versioning as standard practice; production reliability is your default, not a later concern • Cross-functional pragmatism - you work effectively with product and design, can unblock yourself across the stack, and ship workable frontend when that's what's needed • Strong technical depth in: • Python backend (FastAPI or equivalent, async patterns, Postgres, Redis) • LLM integration — building products where AI is in the critical path, not bolted on • API design and data modelling • JavaScript/TypeScript — comfortable enough to ship frontend features and review frontend PRs • Experience with voice agents or real-time audio pipelines • Familiarity with evals, guardrails, or agent observability • Familiarity with GCP / cloud infrastructure • Experience in recruiting tech, marketplaces, or matching systems • A modern Python stack: FastAPI, Postgres, Redis, Docker, Pydantic AI, running on GCP. Frontend in React/TypeScript. We iterate fast and keep the codebase clean.
