Stage - Software Engineer - H/F

About the Role

We're looking for a motivated end-of-study intern (Bac+4/Bac+5, engineering school or university) to join our Engineering team for 6 months and contribute to real product challenges — not a side project, not internal tooling no one uses.

You’ll be embedded in a product squad, working alongside confirmed engineers, a Product Manager, and a Tech Lead who will mentor you throughout your internship. You’ll get hands‑on exposure to our Salesforce ecosystem and learn how a modern engineering team ships software at scale.

This internship is a genuine opportunity to grow fast and, if things go well, a potential path to a full‑time role.

Your Team

You’ll join a tech team of ~20 engineers organised into 4 product squads. Each squad owns a domain and ships continuously. We value:

• Clear ownership and accountability
• Pragmatic engineering decisions
• Strong feedback loops (code reviews, monitoring, retros)
• Continuous improvement in craft and delivery

What You’ll Do

• Learn and contribute to our Salesforce platform: data model, automation logic, and backend features with Apex
• Participate in the design and implementation of integrations between Salesforce and internal/external services
• Contribute to backend services (TypeScript/Node.js) with guidance from your squad
• Work with Product and Design to understand user needs and translate them into working software
• Write clean, tested code and take part in code reviews
• Explore AI‑assisted development tools (Cursor, Claude Code, GitHub Copilot) to accelerate your learning and output

What We're Looking For

• Currently enrolled in a Bac+4 or Bac+5 programme (engineering school, university master's) — end‑of‑study internship preferred
• Solid programming fundamentals: you know how to write clean code, debug, and think through a problem
• Exposure to at least one backend language (Java, Python, C#, TypeScript, or similar), ideally Java
• Genuine curiosity about how software systems work in production
• Good communication in French and English
• Any prior exposure to Salesforce or Apex (coursework, personal project, or previous internship)
• Experience with REST APIs and understanding of web service integration
• Familiarity with Git and basic CI/CD concepts
• Interest in the electric mobility / energy transition space
• TypeScript or Node.js experience

Our Tech Stack

• CRM & Operations : Salesforce (Apex, Flows, Process, Builder)
• Backend : TypeScript, Node.js, microservices
• Infrastructure : Docker, Kubernetes, cloud‑native
• Frontend : Vue.js, React, Next.js
• Python, PHP, NoCode tooling
