AI Automation & Integration Developer Intern (F/M/X) NUOVO

Aufgabe

Decathlon Switzerland is growing fast—projecting 50+ stores and ~500M€ GMV by the end of 2026. To support this massive scale, our HR team needs cutting-edge tools to track and develop our talent

Reporting directly to Raphaëlle, our Learning & Development Leader, you will build a brand-new, AI-powered interface designed to track retail leader performance (skill validation, KPI status, and development plans).

Your goal is to deliver a ready-to-use prototype within 3 months, utilizing the third month for testing, feedback loops, and deployment. You will collaborate closely with both the HR team and our Data Department to seamlessly integrate all necessary data streams.

Autonomy and impact (The reality of this job) As our tech intern within the HR team, you will have a massive playground. We will provide you with the business guidelines and the final vision, but then it is completely up to you to DO it. The HR team does not have the technical skills to code this for you; you will be our absolute tech expert on this project. This is a unique opportunity to create, test, and deliver a highly concrete product in a fast-paced and informal environment!
