Dex - Staff Product Engineer

The role

You will own complete product features from spec to production, mostly on the backend. The work includes a candidate database, a dashboard for the Talent Operations team, and workflows for ranking candidates against a role.

What you will do

• Own product delivery from spec to production, backend-first but covering frontend and integration where needed
• Build and maintain product APIs, data pipelines and core infrastructure on a Python/FastAPI/Postgres stack
• Build product features with significant LLM integration; contribute to the voice agent backend and information extraction systems
• Ship workable React/TypeScript frontend for product features
• Collaborate with product and design to turn ambiguous requirements into concrete shipped work
• Handle data integrity, error paths, API evolution and operational concerns as a default

Required qualifications

• Experience leading teams or entire product lines
• Experience moving fast in scrappy, early-stage environments and seeing what good looks like at scale
• Ability to own and ship end-to-end product slices with minimal supervision
• Product trade-off judgment under ambiguity
• Reliability and API discipline: data integrity, error paths, idempotence and API versioning
• Cross-functional pragmatism with product and design
• Strong technical depth in Python backend (FastAPI or equivalent, async patterns, Postgres, Redis)
• Building products where LLMs are in the critical path
• API design and data modelling
• JavaScript/TypeScript, enough to ship frontend features and review frontend PRs

Nice to have

• 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

Benefits

• Above market salary
• Significant equity
• Full private healthcare and dental
• Fertility benefits and enhanced parental support
• Gym membership and wellness benefits
• Claude tokens
• Regular socials, offsites and an annual trip
• MacBook Pro and team kit
• "Whatever you need" approach to tools and support

Before you apply

• Candidates are invited to try the company's agent, Dex, before applying
• Interview process: a 30 minute video call, a hiring manager call, a practical task usually completed offline, and an onsite loop with a final interview with the Founder
