• Experience taking over production platforms with limited knowledge transfer, improving release processes, and simplifying fragmented microservice architectures.

🟠 Responsibilities:

• Lead the technical assessment, stabilization, and ongoing improvement of the existing production platform.
• Analyze the existing architecture, service dependencies, data flows, databases, message queues, and external integrations to identify technical risks and improvement opportunities.
• Review the current architecture, identify areas for simplification, reduce technical debt, and contribute to the platform's long-term evolution.
• Investigate and resolve complex production issues, including cross-service communication and data consistency challenges.
• Improve system reliability, maintainability, observability, and deployment processes, including CI/CD, database migrations, and rollback strategies.
• Establish and promote engineering best practices for development, code reviews, testing, and release management.
• Provide technical leadership, mentor engineers, and actively contribute to the implementation of complex technical solutions.
• Collaborate closely with the Delivery Manager, DevOps/SRE, QA, and the client's technical lead to deliver a reliable and scalable production platform.
