## Description

We're looking for senior backend engineers with deep Java and Spring expertise to help modernize our platform. The team already runs on Java 21 and is now upgrading frameworks and components across the stack, including moving from Dropwizard to Spring Boot and breaking parts of a monolith into microservices. Once the migrations are done, you'll move into ongoing product development, so this is a long-term role, not a short project. We need engineers who can lead technical work on their own and bring real depth in Java, not just familiarity with it., * Lead major-version upgrades and framework migrations (e.g., Dropwizard to Spring Boot) from planning through delivery

 * Modernize legacy and monolithic components and help move them toward a microservices architecture
 * Design, build, and maintain Java microservices with Spring Boot and the wider Spring ecosystem
 * Containerize and deploy services with Docker and Kubernetes
 * Work with SQL Server to design, optimize, and maintain application data
 * Build and maintain strong automated test coverage so migrations and new features ship safely
 * Contribute to new product development once migration work is complete
 * Mentor peers and raise the team's technical standards through code reviews and design discussions
