Sr Software Engineer

About the role

Every design decision — from threading models to deployment topology — is made with high throughput, sub-millisecond latency, and five-nines availability in mind. This is a full-stack engineering role in the deepest sense: you will design and build features end to end, own the reliability and performance of what you ship, actively contribute to the CI/CD pipeline and quality strategy, and provide L3 production support when the platform counts on it.

What you'll do

• Design, implement, and optimize high-performance Java services for real-time transaction processing: payments, authorization, clearing
• Apply deep JVM knowledge — threading models, garbage collection tuning, lock-free data structures, and async I/O — to sustain predictable throughput under peak load
• Define and enforce performance budgets: author benchmarks, regression tests, and latency SLOs; profile and root-cause regressions before they reach production
• Build against modern cloud-native patterns: microservices, event-driven messaging (NATS), reactive pipelines, and 12-factor application design
• Cloud-Native & Container-First Development
