Missions
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
