Senior Java Developer - Microservices & Spring | Remote

Headquarters: Remote

URL: https://www.toptal.com/

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
