• Reliability: Implement monitoring, debugging tools, and comprehensive test suites (unit, integration, and E2E).
• Mentorship: Provide technical guidance to junior developers and foster a culture of knowledge sharing.
• Problem Solving: Analyze complex technical problems and propose effective, production-grade solutions.

Requirements

• Location: Must be based in the EMEA region.
