Lead Java Developer
Job Description
Role Summary: We are looking for a Java Full-Stack Engineer to design, build, and support modern web applications. This role spans front-end development (Angular or React) and back-end services (Java/Spring Boot), with a focus on API-first, microservices-based architecture and CI/CD-driven delivery.
Key Responsibilities
- Develop and maintain web applications across the stack: UI, APIs, and backend services.
- Build scalable, secure microservices using Java and Spring Boot.
- Develop responsive user interfaces using Angular, leveraging Kendo UI components where appropriate.
- Implement and support micro front-end patterns (composition, shared libraries, module federation or equivalent approaches).
- Design, build, document, and consume RESTful APIs; ensure service contracts and versioning strategies are followed.
- Work with SQL Server and optimize queries, indexes, and data access patterns.
- Implement search and indexing solutions with Elasticsearch.
- Build event-driven integrations using Kafka (producers/consumers, topics, schema/versioning awareness).
- Use GitHub / Bitbucket and contribute to automated CI/CD pipelines (build, test, deploy).
- Write unit and integration tests; participate in code reviews and engineering best-practice adoption.
