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 a solid 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.
