Senior Fullstack Engineer

Job description

## **🎯** 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. ## Compensation & Benefits - 💸 BSPCE + 60–75k€ gross annual, depending on profile - 🏡 Hybrid work (3 days minimum on-site, Paris 9th) - 🏝 Contrat cadre and RTT (between 8 and 12 days per year depending on public holidays) - 💻 A Mac or PC depending on your preferences - 🍜 60% coverage of meal vouchers worth €9 per worked day - 🚃/🚲 Sustainable mobility allowance - 🏥 Mutuelle (Alan) - 💼 Offices located in central Paris (9th arrondissement) - ☀️ Annual offsite with the whole team and plenty of company events *If you've read this far, you're probably very interested in the role and/or Vizzia.
