Java Microservices Developer

The Microservices Developer will be responsible for designing, building, and maintaining scalable backend services that power the platform’s RESTful APIs. This role involves developing production-grade microservices using Java 21 and Java 25, implementing clean and consistent API contracts, and ensuring secure, reliable integration with internal and external systems. The developer will collaborate closely with product, architecture, and QA teams to deliver high-quality releases, support deployment and validation in staging and production, and troubleshoot issues across distributed environments. Over time, the developer will drive improvements in service performance, resiliency, and observability while contributing to shared engineering standards, reusable components, and automation across the microservices ecosystem.
