Job Description
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
