  • Maintain and update functional and technical documentation of existing assets.
  • Participate in UAT, ITRM risk analyses, IAM permissions setup, and deployment follow-up (CD Toolchain).
  • Collaborate with business and technical teams (in English and/or French) for requirement analysis and validation.
  • Support a portfolio of existing applications, monitor incidents, and ensure service continuity.
  • Contribute to Agile ceremonies and promote continuous improvement.
  • Work autonomously within a flex-office / hybrid setup, ensuring rigor and clear communication across distributed teams.

What we're looking for:

  • Solid experience with Java (Spring Boot) + front-end frameworks (Angular or ReactJS), hands-on experience with Elastic Search is a plus.
  • Strong understanding of Agile / CI-CD / secure software development.
  • Previous exposure to financial or enterprise systems is an advantage.
  • Fluent English (spoken & written); French is a plus.

What's in it for you:

  • End-to-end involvement in full-lifecycle projects used across Europe.
  • Modern tech stack + real impact in a stable, regulated industry.
  • International collaboration with multicultural teams.
  • Balance between stability and innovation in a regulated environment.
  • Hybrid model promoting autonomy, trust, and work-life balance.
