About the Role

We're looking for a Senior Java Developer to design, build, and scale backend services for a high throughput, low latency platform with strict reliability and auditability requirements. You'll own end to end delivery—from design to production—collaborating closely with Product, QA, and Dev Ops

Responsibilities

Design and implement microservices and event-driven components in Java (preferably Java 17+). Model and optimize Postgre SQL schemas, queries, and transactions for performance and integrity. Build resilient, observable services on AWS (ECS/EKS/Lambda, S3, RDS/Aurora, MSK/Kinesis, IAM). Ship with strong CI/CD practices (Git Hub Actions) and leverage Git Hub Copilot to accelerate high quality delivery. Ensure reliability, scalability, and fault tolerance (circuit breakers, retries, idempotency, backpressure). Implement security and compliance controls (authz/authn, secrets, IAM policies, encryption at rest/in transit).

Own production operations: monitoring, troubleshooting, and performance tuning. Contribute to architecture decisions, code reviews, and engineering standards.
