• Practical experience with Redis (caching strategies, counters, and distributed rate-limiting patterns)

• Experience designing or working with authorization and policy systems (RBAC/ABAC concepts)

• Strong testing discipline in Go (table-driven tests, mocks, integration tests, and test containers)

• Experience operating production systems with observability tooling (OpenTelemetry metrics and tracing, dashboards, and alerting)

• Solid experience with Kubernetes and Helm deployments

• Strong CI/CD experience (GitHub Actions or equivalent)

• Demonstrated ability to lead technical design and execute independently, end-to-end

• Familiarity with GenAI concepts and OpenAI APIs, with a drive for self-learning

• Familiarity with AI-centric development while maintaining strong controls on quality and architecture patterns

• Good communication and collaboration skills

• English level of minimum B2 (Upper-Intermediate) for effective communication

Nice to have
