Backend Software Engineer

Context

Two video surveillance products are entering development at Vizzia: video-based traffic enforcement, with a first deployment in the UK, and ANPR, automatic number plate recognition run on legal request. Both rely on the same technical chain: camera-equipped units in the field, an edge to cloud pipeline, and a SaaS that officers use every day. That chain has to be built.

Vizzia equips more than 250 local authorities for waste management today. Safety is the company's second product line, and it comes with its own constraints: data hosted in France on SecNumCloud infrastructure, evidential integrity, end to end traceability.

The team is small and senior. You will join Jérémy Fornarino, Tech Lead, as the second backend engineer on Safety. Your mission: take ownership of a significant share of the backend for both products, across the full edge and cloud spectrum, and raise the team's quality bar alongside him.

1. The edge backend

2. The cloud backend

3. Ship enforcement and ANPR to production

4. Architecture and quality

Current stack: TypeScript end to end, bun, Hono, Drizzle, Postgres on the cloud side, SQLite on the edge, LavinMQ bus, moon monorepo, GKE, Datadog. Infrastructure and DevOps experience is welcome but not a prerequisite, you can pick it up here.

Two bonus profiles, not prerequisites: video and streaming experience (codecs, containers, VMS), or a background in IoT, embedded or robotics. Domain knowledge can make up for a shorter SaaS track record.

At Vizzia we work in a small team, with a lot of ownership and few silos. We are looking for someone who picks up topics without waiting, argues their choices, and genuinely cares about the problems the public sector is trying to solve.
