Job description

About the Role

As a Senior Java Developer, you will lead design and delivery of mission‑critical microservices for our corporate & investment banking platforms. You’ll set engineering standards, mentor developers, and partner with architects and platform teams to deliver resilient, performant services in production.

Key Responsibilities

• Own end‑to‑end technical delivery: design, implementation, testing, deployment, and support
• Design fault‑tolerant microservices with robust API contracts, idempotency, and back‑pressure
• Optimize performance (profiling, JVM tuning, connection pools, serialization choices)
• Lead secure SDLC practices (threat modeling, SAST/DAST, secrets mgmt, least privilege)
• Guide container/k8s deployment patterns (HPA, pod disruption budgets, graceful shutdown)
• Champion observability and reliability (SLOs, error budgets, chaos testing where applicable)
• Mentor engineers; uplift code quality, reviews, and documentation standards
• Partner with stakeholders across payments/trade/markets to scope and prioritize work

Required Skills & Experience

• 7+ years’ engineering experience in Java 11/17, Spring Boot, and distributed systems
• Proven track record in high‑throughput services, messaging (Kafka/MQ), and RDBMS tuning
• Hands‑on with Kubernetes/OpenShift, CI/CD, and production support in regulated environments
• Deep understanding of testing strategy, clean architecture, and performance tuning
• Excellent stakeholder and technical leadership skills

Nice‑to‑Have

• Experience with low‑latency patterns (lock contention, GC strategy, off‑heap caching)
• Exposure to gRPC, NoSQL, in‑memory data grids, or event sourcing
• Familiarity with domain concepts (ISO 20022 payments, SWIFT, trade lifecycle, market connectivity)

What We Offer

• Technical leadership scope with regional impact
• Hybrid work, continuous learning, career mobility across global teams
• Competitive compensation and comprehensive benefits
