Senior Software Engineer

Senior Java Engineer - High-Scale Banking Platform - Multiple roles from $160-220k + super + bonus

Build and evolve mission-critical banking systems processing millions of transactions daily. We're talking sub-100ms P99 latencies, five-nines availability, and zero-downtime deployments across personal and business banking platforms.

The Stack

• Core: Java 17+, Spring Boot 3.x, reactive streams
• Cloud: GCP (GKE, Cloud Run, Pub/Sub, Cloud SQL, Spanner)
• Data: PostgreSQL, distributed caching, event-driven architectures
• Observability: Full distributed tracing, metrics pipelines, chaos engineering
• CI/CD: GitOps, containerized deployments, progressive rollouts

What You'll Actually Do

• Design high-throughput, fault-tolerant microservices that handle money (yes, that kind of pressure)
• Tackle distributed systems challenges: eventual consistency, idempotency, circuit breakers, rate limiting
• Optimise JVM performance, database queries, and network I/O for millisecond-level improvements
• Lead technical design reviews and mentor engineers on patterns that matter at scale
• Own production: you build it, you run it—full observability and incident response

What We're Looking For

• Deep Java expertise with real production war stories
• Strong fundamentals: concurrency, memory management, profiling, performance tuning
• Experience building resilient distributed systems in the cloud
• You've debugged gnarly production issues at 2 AM and lived to optimize for them
• Pragmatic about technology choices—you know when to use the boring solution
• Comfortable with high-stakes environments where correctness and reliability are non-negotiable

Why This Role

• Work on genuinely complex engineering problems with significant scale
• Modern tech stack with engineering autonomy
• Collaborate with strong engineers who care deeply about craft
• Financial services domain knowledge (without the legacy pain)
