• Define API and event contracts, sequence flows, schemas, versioning, and backward compatibility

• Implement observability using structured logging, metrics, distributed tracing, and integration SLA alerting

• Leverage AI-assisted development tools such as Claude Code, GitHub Copilot, or Cursor while maintaining strong code quality and security standards

• Contribute to CI/CD, automated testing, contract/integration testing, load testing, failover, and resiliency validation

• Strong knowledge of goroutines, channels, context propagation, error handling, and interface-driven design

• Experience with REST and/or gRPC services

• Ability to profile and tune Go services for memory, concurrency, and latency

Enterprise Integration:

• Strong understanding of enterprise integration patterns and their real-world trade-offs

• Experience with synchronous vs. asynchronous integration, orchestration vs. choreography, guaranteed delivery, at-least-once delivery, and idempotent consumers

• Understanding of canonical data models, transformation, mapping, and domain-based contracts

• Exposure to an iPaaS platform such as MuleSoft, Boomi, Workato, Azure Logic Apps, Informatica, TIBCO, webMethods, or similar

• Strong understanding of clean architecture, SOLID, design patterns, and domain boundaries
