• Commitment to delivering quality, well-tested, maintainable code
• Strong problem-solving abilities and autonomy in driving solutions

📍 Location: Paris with 3 days remote per week

• Experience with microservices architectures
• Familiarity with automated testing strategies (unit, integration, contract testing)
• CI/CD pipelines and deployment workflows
• Cloud platforms (AWS, GCP, Azure) and containerization (Docker, Kubernetes)
• Production monitoring, logging, and debugging experience
• Agile methodologies, code reviews, and collaborative practices
• Security best practices for backend systems

⭐ What will really make the difference
