Job Description

A Java Back-end Developer focuses on building robust, secure, and highly-available server-side systems and APIs that power products, working closely with front-end engineers and architects to ensure performance benchmarks are consistently met.

What We Expect From You:

  • Design and implement microservices and distributed systems using Java and the Spring ecosystem, following established architectural patterns.
  • Develop secure, high-performance RESTful APIs that are consumed reliably by both web and mobile client applications.
  • Model, optimise, and manage relational and NoSQL databases to support scalable, data-intensive workloads.
  • Implement authentication and authorisation mechanisms using OAuth2, JWT, and Spring Security best practices.
  • Identify and resolve performance bottlenecks through profiling, load testing, and targeted refactoring of critical code paths.
  • Integrate third-party services, payment gateways, and external APIs in a maintainable and testable way.
  • Write comprehensive unit and integration tests to maintain high coverage and prevent regressions across services.
