Focal Systems builds AI camera networks for grocery retail. Hundreds of stores, major UK and European chains, and a customer list that keeps growing faster than most companies our size would attempt. The computer vision market is moving, and we're one of the few places actually deploying it at scale - not on slides, but in stores equipped with hundreds of shelf edge cameras that change how store teams do their jobs every shift.
Our Customer Integration team has taken every major retailer we've signed through production — and as we add more customers, we’re looking for a senior engineer to lead high-quality deployments, own onboarding and integrations end-to-end, and help define how this function grows.
What You'll Do
- Work with a real distributed AI system at scale — when a retailer's report is wrong, a pipeline is silently dropping events, task counts diverged somewhere between Kafka, Redis, MySQL, and MongoDB, you'll own the challenged end-to-end, not hand it off after one layer.
- Bring new customers live — map their data formats to ours and validate pipel
