Vizzia deploys connected cameras and smart infrastructure for 250+ local authorities across France. Behind the product that local cities see sits a less visible but equally critical layer: the platform that keeps the fleet running.
The DLM team builds and maintains that layer. FleetAPI, drift detection, the status engine, internal tooling for Ops and Hardware teams, provisioning workflows — if a camera is misconfigured, if a fleet is drifting, if an operator needs to act fast, it's this team's stack that makes it possible or not.
🛠️ What You'll DoYou will develop and maintain the internal tools used daily by Ops and Hardware teams :
1. Build and maintain backend services
Design and ship features on internal dashboard (Node.js, TypeScript, React).
Write clean REST APIs with proper OpenAPI specs.
Work on event flows and data pipelines where needed (the team uses AWS).
Contribute to infra-adjacent work alongside the senior cloud engineer (CDK, AWS).
2. Ship frontend where it matters
Develop interfaces in React & Tailwind (or equivalent libs) for internal clients.
The team isn't looking for a frontend specialist, but you need to be comfortable enough to own your front without handholding.
3. Contribute to architecture and process discipline
Challenge specs coming from the Tech Lead & PM, raise concerns early, not after.
Participate in code reviews, architecture proposals, incident response within your perimeter.
Tickets are contracts: requirements are delivered or escalated before shipping.
Mentor future junior hires as the team grows.
You have 3 to 5 years of full-stack experience in production environments, with solid TypeScript / Node.js and real React or Vue usage.
You've shipped features end-to-end and owned an area, including the boring parts: monitoring, on-call, post-incident reviews.
You have knowledge of AWS in production (Lambda, S3, RDS) and some exposure to IaC (Terraform or CDK).
You operate well within a scope set by a Tech Lead and a PM. You surface ideas through the right channels and treat ticket requirements as commitments.
French preferred; fluent technical English is fine.
If you've worked on IoT, fleet systems, or internal tooling before, that's a strong signal. It's not a prerequisite.
