Min requirements:

• Extensive professional experience in Golang, with a deep understanding of its core principles and performance optimization.

• Strong background in designing microservices capable of handling massive request volumes and high availability.

• Hands-on experience with AWS services, Docker, and Kubernetes (scaling pods, log management, config maps).

• Advanced knowledge of Relational databases and the ability to architect Non-Relational persistence layers for specific data domains.

• Proficient in creating comprehensive unit, integration, and End-to-End (E2E) test suites covering entire business journeys.

Would be a plus:

• Experience with payment services, ledger systems, or banking metadata patterns.

• Familiarity with Argo, Codefresh, or custom CI/CD pipelines (e.g., Goalkeeper).

• Experience with distributed tracing and complex alerting logic in high-load environments.

• Deep understanding of specific patterns like Integrity Queues or advanced idempotency logic.

We offer:
