About the role

We’re looking for a Backend Engineer with strong expertise in Java and Spring Boot to join our high-impact engineering team.

In this role, you’ll design and build scalable, resilient, and secure backend systems that power mission-critical applications. You’ll collaborate closely with product managers, architects, and other engineers to deliver reliable, high-performance services that scale.

What You’ll Do

• Design and develop distributed microservices using Java and Spring Boot, applying clean architecture and domain‑driven design (DDD) principles.
• Build resilient, event‑driven systems using Spring Cloud, Kafka (or RabbitMQ), and circuit breaker patterns.
• Optimize backend performance through JVM tuning, efficient Spring Data / JPA strategies, Redis caching, and code profiling.
• Secure APIs using Spring Security, OAuth2, and JWT, ensuring compliance with best practices for data privacy and security.
• Define and evolve API contracts using OpenAPI / Swagger, contributing to shared backend libraries and internal developer platforms.
• Implement automated testing using JUnit 5, Testcontainers, and integration testing for robust service reliability.
