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.
