Senior Java Developer — Microservices &amp Spring Remote

About the Role -------------- We're looking for a Senior Java Developer to design, build, and maintain scalable backend systems using Java, Spring, and a microservices architecture. This is a hands-on engineering role: you'll own services end to end, from data modeling through deployment, while collaborating closely with cross-functional teams to deliver production-ready solutions. If you're comfortable owning backend architecture decisions and writing clean, maintainable code at scale, this is built for that. What You'll Do -------------- * Design, develop, and maintain backend services and APIs using Java and the Spring ecosystem (Spring Boot, Spring Cloud, Spring Data) * Build and evolve microservices architecture, including service decomposition, inter-service communication, and API design * Design and optimize relational database schemas and queries using SQL * Implement RESTful APIs and support integration with third-party systems and internal services * Write clean, testable, production-quality code, including unit and integration tests * Troubleshoot and resolve performance, scalability, and reliability issues across distributed services * Participate in code reviews, architecture discussions, and technical planning * Support CI/CD pipelines and deployment processes for microservices * Collaborate with cross-functional teams (frontend, QA, product) to deliver features end to end * Contribute to technical documentation and best practices for the engineering team What You Bring -------------- * Strong hands-on experience with Java in a production backend environment * Solid experience with the Spring framework (Spring Boot, Spring MVC, Spring Data, Spring Cloud) * Proven experience designing and building microservices architectures * Strong SQL skills, including schema design, query optimization, and relational data modeling * Experience with RESTful API design and development * Understanding of distributed systems concepts (service communication, fault tolerance, scalability) * Experience with version control (Git) and CI/CD workflows * Strong problem-solving skills and ability to work independently on complex technical challenges * Solid communication skills for collaborating with cross-functional and distributed teams Nice to Have ------------ * Experience with containerization and orchestration (Docker, Kubernetes) * Experience with message queues or event-driven architecture (Kafka, RabbitMQ) * Familiarity with cloud platforms (AWS, Azure, or GCP) * Experience with NoSQL databases alongside SQL * Familiarity with monitoring and observability tools (Prometheus, Grafana, ELK stack) Why This Role ------------- * Real architectural ownership: Shape microservices design decisions, not just implement tickets * Modern stack: Work with current Java, Spring, and microservices best practices * Cross-functional collaboration: Work closely with product, QA, and frontend teams on end-to-end delivery * Flexibility: Remote-friendly engagement structure How to Apply ------------ Ready to bring your Java and microservices expertise to a production-grade system?
