Description

You will design and implement high-performance backend services in Java, building and evolving reactive, event-driven architectures processing millions of events. You'll contribute to batch pipelines, real-time streaming flows, and optimize distributed systems on AWS and OpenShift, focusing on performance and resilience.

Requirements

• 7+ years of backend engineering experience with strong Java expertise
• Proven experience building and operating large-scale event processing systems
• Hands-on experience with reactive programming (Project Reactor, WebFlux, RxJava)
• Strong experience with event-driven architectures (Kafka, SQS/SNS, RabbitMQ)
• Strong PostgreSQL performance tuning skills including JSONB optimization

Responsibilities

• Design and implement high-performance backend services in Java
• Build and evolve reactive, event-driven architectures handling millions of events
• Optimize JVM performance including GC tuning, thread pools, and non-blocking I/O
• Design flexible NoSQL document-style data models and optimize PostgreSQL including JSONB queries
• Implement observability practices with metrics, tracing, and distributed logging
