Senior MES Developer (Backend + Angular)

The primary mission of this role is to deliver and harden MES microservices that sustain 2000+ txn/s for by-unit tracking workloads, reduce data and transaction concurrency pressure on Opcenter MES, and support ongoing production growth.

Responsibilities:

• Partner with the Technical Architect to turn architecture decisions into production services, interfaces, and operational controls.

• Deliver by-unit tracking MES microservices that sustain 2000+ txn/s under production-like load.

• Build low-latency, high-concurrency backend services in Java/Spring Boot with clear API contracts and domain boundaries.

• Tune application and database performance across SQL, indexing, execution plans, transaction boundaries, lock contention, and connection pools.

• Build persistence and data-access strategies for current Progress workloads while keeping schema and query patterns PostgreSQL-ready.

• Implement event-driven integrations with Opcenter and enterprise systems such as SAP, WMS, DataHub, and equipment/IIoT platforms.

• Design resilience patterns for production, including idempotency, retry, circuit breaking, timeout budgets, bulkheads, and graceful degradation.

• Own observability for critical transaction paths, including metrics, traces, structured logs, dashboards, alert thresholds, and runbooks.

• Run load and performance tests with QA and DevOps, analyze bottlenecks, and iterate until throughput and stability targets are met.

• Support selected Angular changes for by-unit workflows and operational visibility where API behavior and UX performance must align.

• Troubleshoot high-severity production issues through deep RCA and deliver preventive actions with measurable impact.

• Strengthen CI/CD quality gates with performance and reliability checks before release promotion.

• Produce concise technical documentation, including architecture implementation notes, NFR baselines, benchmark reports, and operational runbooks.

• 6+ years of s
