Role Overview
Take ownership of a significant share of the backend for both video-based traffic enforcement and ANPR products, across the full edge and cloud spectrum, and raise the team's quality bar alongside the tech lead.
About Vizzia
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.
Key Responsibilities
- Build and operate the services running on the field units: camera communication, NX Witness integration, local SQLite storage
- Optimise CPU and RAM on units with limited resources, and minimise the 4G/5G bandwidth of the video chain
- Design and operate the Hono APIs, the event-driven workers on the LavinMQ bus, and the Postgres/Drizzle data layer
- Co-own both enforcement and ANPR projects from technical spec through to production
- Write your own ADRs, challenge existing ones, and ship every module tested
Requirements & Eligibility
- 4 to 8 years of backend experience, a significant part of it in SaaS
- TypeScript/Node in production, operational from day one
- Experience building and operating event-driven distributed systems in production
- An engineering degree or a master's
