Experienced Full-Stack Java Developer

About the Role

We are looking for an experienced Full-Stack Java Developer to join our multidisciplinary product/project team and contribute to the design and development of mission-critical microservice systems, working across the entire application lifecycle—from data modeling and distributed architecture to automated deployment on Kubernetes and OpenShift—in a collaborative and innovative environment.

Key Responsibilities

• Design: Participate in design workshops, produce UML artifacts, define API contracts, and model data and service boundaries
• Develop: Implement Spring Boot (or Quarkus) microservices and Angular interfaces, with non-negotiable standards for code quality and test coverage
• Scale: containerize your services (Docker), package them (Helm), deploy and operate them on Kubernetes/OpenShift, and contribute to CI/CD pipelines
• Ensure reliability: instrument systems (logs, metrics, traces), handle resilience (retry, circuit breaker, idempotence), and participate in post-incident analyses
• Raise the bar: conduct code reviews, mentor junior team members, and contribute to the team's technical standards
• Use AI wisely: integrate AI assistants (Claude, Copilot, Cursor, etc.) into your workflow—including code generation, refactoring, testing, and documentation—while systematically applying a critical eye to the output

Required Qualifications

• Degree in computer science or equivalent experience
• Experienced full-stack developer: 3 to 5 years of experience with Spring Boot / Angular (or Quarkus / Angular)
• Conceptual mastery of UML, system design, and data design: you know how to model before coding and justify your design choices
• DevOps practitioner: Docker, Docker Compose, Kubernetes or OpenShift, Helm packaging, CI/CD. Real-world experience, not theoretical
• Experience with an AI assistant: actual use in a professional context, and the ability to explain its benefits and limitations
• Technical proficiency in French and English (reading/writing) required

Nice to Have

• Experience with microservices architectures and messaging systems (Kafka, RabbitMQ)
• Knowledge of distributed patterns (Saga, Outbox), API Gateway, and Service Discovery
• Experience in application security with OAuth2/OIDC, Keycloak, and the OWASP Top 10
• Knowledge of observability tools (Prometheus, Grafana, ELK/Loki, OpenTelemetry)
• Experience with advanced testing (Testcontainers, contract testing, load testing)
• Experience in mission-critical or regulated environments (telecom, banking, healthcare, public sector)

What We Offer

• Competitive salary and performance bonuses
• Remote work: Remote work available with approval
• Professional development budget for training and certifications
• A Clear Career Path: [Senior → Tech Lead / Architect]
• External access to AI assistants and time dedicated to developing skills in using these tools
