Software Developer- Front End - Senior
Summary:
Join our team as a Senior Integration Developer to support the modernization of legacy driver and vehicle systems. You'll design and implement Spring Boot microservices, integrate with external systems using secure protocols like OAuth2 and JWT, and optimize performance with Redis caching and asynchronous workflows. The role requires hands-on experience with Azure services, AKS, CI/CD pipelines, and containerized deployments. You’ll be responsible for systems and data impact analysis, scripting, and documentation, with ongoing knowledge transfer to ministry staff. Ideal for professionals with strong problem-solving skills and deep expertise in distributed systems and orchestration using Azure Durable Functions. Hybrid work required (3 days onsite).
