Job offer : Freelance Java / Angular / AWS Cloud Lead Developer (M/F) - Lyon

We are looking for a freelance mobile Java / Angular / AWS Lead Developer in Lyon to lay the technical foundations for a new business solution dedicated to traceability and interventions in constrained industrial environments. The product is in the full design phase of its MVP (Minimum Viable Product) on a modern cloud base.

YOUR MISSIONS

Architecture & technical scoping: define architecture guidelines on AWS, secure implementation choices, and build a robust and scalable foundation from the launch phase. Hands-on development (60 to 70%): actively participate in the development of the solution with a backend focus (70% Java / Spring Boot) and a frontend component (30% Angular). Technical leadership (30 to 40%): lead and upskill a team of 4 to 5 developers, establish delivery best practices, and arbitrate technical choices.

Accustomed to construction from scratch or product launch phases (MVP), with a real architectural vision. Rigor, team spirit, and an appetite for mentoring (a first Lead experience is valued, but not essential).

Profile combining fullstack expertise, technical design, and cloud experience, ideally having worked on building applications or new products.
