About the role

Key responsibilities & impact

Build and maintain backend services
Design and ship features on the internal dashboard (Node.js, TypeScript, React).
Write clean REST APIs with proper OpenAPI specifications.
Work on event flows and data pipelines as needed (the team uses AWS).
Contribute to infra-adjacent work alongside the senior cloud engineer (CDK, AWS).
Ship frontend where it matters.
Develop interfaces in React & Tailwind (or equivalent libraries) for internal users.
Contribute to architecture and process discipline.
Challenge specifications from the Tech Lead & PM; raise concerns early rather than later.
Participate in code reviews, architecture proposals, and incident response within your area.
Mentor future junior hires as the team grows.

Requirements

What you’ll need

Solid full-stack experience in production environments, with strong TypeScript / Node.js and real React or Vue usage.
You have shipped features end-to-end and owned an area, including the unglamorous parts: monitoring, on-call, and post-incident reviews.
Knowledge of AWS in production (Lambda, S3, RDS) and some exposure to IaC (Terraform or CDK).
You work 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 acceptable.
Experience with IoT, fleet systems, or internal tooling is a strong plus but not required.
