vizzia

Senior Fullstack Engineer

🎯 Context

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 Do

You 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.

✅ Who You Are

  • 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.
