• structured logging, log levels, correlation, traceability;
• metrics and monitoring (service health, queues, processing time, errors);
• alerting and support-friendly diagnostics;

• Experience with application and/or network security.
• Experience (or strong motivation) using AI tools to support development.
• Ability to work in French
