Senior Product Engineer
Dex, London
The role
This is a full-stack product role with a backend-heavy centre of gravity. You'll own complete product slices end-to-end — things like a candidate database with rich search and filtering, a dashboard that surfaces call transcripts and match history for our Talent Operations team, and the workflows that let them stack-rank candidates against a new role in minutes rather than hours. You ship these without needing to be guided step by step.
You're not a specialist who hands off at the API boundary. You think in user outcomes and delivery units, and you're reliable: your code handles edge cases, your APIs have clean contracts, and the work you ship stays shipped.
What you will do
- Own product delivery – take features from spec to production, backend-first but covering frontend and integration where needed
- Build and maintain backend systems – product APIs, data pipelines, and core infrastructure on our Python/FastAPI/Postgres stack
- Build with LLMs and agents – ship product features with significant LLM integration; contribute to the voice agent backend and information extraction systems
