In this role, you will modernize mission-critical services written in VC++ by migrating them to Java and shaping them into distributed, event-based, cache-driven micro-services using state-of-the-art cloud-native services and infrastructure. You will help establish a platform foundation that enables operational intelligence/observability, end-to-end traceability, and complete auditability.
Key Responsibilities

• Modernize legacy VC++ services into Java: translate functionality while improving modularity, maintainability, and test coverage; migrate supporting components and dependencies as needed (e.g., moving from Microsoft foundation class patterns to Java alternatives)
• Build cloud-native, modular microservices as part of a unified accounting platform architecture, targeting scalability and high availability.
• Design and implement event-driven processing (pub/sub patterns) for near real-time workflows and downstream integrations, aligned to platform “real-time event-driven processing” goals.
• Implement cache-driven performance patterns (e.g., distributed caching, read models, materialized views) to support high-throughput/low-latency accounting workloads.
• Drive engineering rigor and parity during migrations: ensure functional equivalence where required, and evolve unit/integration testing to maintain confidence during C++ to Java transitions.
• Deliver end-to-end traceability and strong operational readiness using comprehensive observability (logging/metrics/tracing), supporting the platform’s operational intelligence goals.
• Collaborate with product, architecture, and upstream/downstream teams to integrate Investment Accounting services into broader ecosystem flows (e.g., transaction processing distribution patterns and validated event ingestion).
• Contribute to platform standards for service design, API contracts, event schemas, resiliency (retries/idempotency), and secure-by-design practices.

Required Skills

• Strong hands-on backend engineering experience with VC++ (modern C++) and Java in production systems.
• Proven track record modernizing legacy codebases (C/C++ to Java preferred), including refactoring for modularity and maintainability.
• Experience building distributed systems: concurrency, synchronization, fault tolerance, idempotency, ordering, and throughput tuning.
• Knowledge of event-driven architectures (streaming/messaging concepts), including designing event contracts, consumers, and processors.
• Strong understanding of performance engineering: profiling, memory/CPU optimization, latency reduction, and capacity planning.
• Solid testing discipline: unit/integration testing strategies, regression protection, and automation in CI/CD.
