Senior Software Engineer | TypeScript & AI

Most important qualities for this role at Tracklab
* You ship. You have a track record of features that went to production and stayed there
* You are pragmatic about quality: you know the difference between the corner that can be cut and the one that will cost six months
* You challenge the spec. When something does not make sense, you say so before you build it, not after
* You are comfortable in a codebase you did not write, in a domain you do not know yet
* You use AI as a real multiplier and you read every line it produces
* Entrepreneurial mindset: you thrive in a fast-moving environment where the answer is rarely written down anywhere
Skills & experience
Must haves
* 3+ years of professional software engineering, including at least one company with a serious engineering culture
* Strong TypeScript, on both sides of the stack
* Solid relational data modeling and SQL. You can design a schema, not just query one
* You already code with AI daily (Claude Code, Cursor or equivalent) and you can explain where it fails
* Clear written communication in French and English
* You have owned features end to end, including what happened after the release
Nice to haves
* NestJS and Next.js in production
* GCP, Terraform, CI/CD pipelines
* Python
* B2B SaaS with deep data models: PLM, PIM, ERP, MES, QMS or similar
* Experience in agri-food, cosmetics, chemicals or another regulated industry
Our stack
TypeScript everywhere. NestJS on the backend, React / Next.js on the frontend, PostgreSQL (Cloud SQL) and Redis. Infrastructure on GCP, managed with Terraform. Python for our AI and data work. GitHub for everything.
