Senior Go (Golang) Developer

About the Role
You'll spearhead a green-field Go service that removes CPU-heavy XML parsing from the mainframe. The component will validate messages against XSDs, enforce rate limits, return meaningful errors, and dispatch valid calls to CICS via CTG. Speed to production is critical: first release in 4–8 weeks.

Key Responsibilities

• Design and code a concurrent Go service handling XML-over-HTTP at scale (thousands TPS)
• Implement XSD-based validation and extra business-rule checks; surface precise error payloads
• Introduce token-bucket or leaky-bucket rate limiting; plan for future caching (Redis or Memcached)
• Integrate with CICS Transaction Gateway for request dispatch; collaborate with COBOL engineers to mirror existing logic
• Write exhaustive unit, integration, and load tests (Go test, k6, Vegeta)
• Automate build and deployment via Git, Jenkins, Docker, and optional Kubernetes or ECS
• Instrument the ser...
