We are seeking a talented and motivated Full Stack Developer with 2 to 4 years of experience in building scalable, robust web applications using Java (Spring Boot) and Angular. In this role, you will be responsible for designing, developing, and maintaining end-to-end features, crafting responsive user interfaces, and implementing high-performance microservices and RESTful APIs. You will work closely with cross-functional teams including product managers, UI/UX designers, and QA engineers in an Agile environment.
Key Responsibilities
1. Frontend Development (Angular)
- Design and implement responsive, accessible, and high-performance UI components using Angular (v12+), TypeScript, HTML5, and SCSS/CSS3.
- Manage state and asynchronous data streams utilizing RxJS and modern Angular reactive patterns (and/or NgRx).
- Ensure cross-browser compatibility and optimize frontend loading performance and rendering efficiency.
- Collaborate with UI/UX designers to translate wireframes and user stories into clean, functional code.
2. Backend & API Development (Java / Spring Boot)
- Develop, test, and deploy resilient microservices and RESTful APIs using Java (Java 11/17+) and the Spring Boot ecosystem (Spring MVC, Spring Data JPA, Spring Security).
- Implement efficient business logic, data validation, exception handling, and secure authentication/authorization (OAuth2, JWT).
- Optimize backend processing for low latency, scalability, and high availability.
3. Database & Data Integration
- Write and optimize complex queries, stored procedures, and schema migrations using relational databases (such as PostgreSQL, Oracle, or MySQL).
- Utilize ORM frameworks like Hibernate / Spring Data JPA effectively, preventing performance pitfalls (e.g., N+1 query issues).
- Work with caching layers (such as Redis) and message brokers (such as Kafka or RabbitMQ) where applicable.
4. Quality Assurance, DevOps & CI/CD
- Write clean, maintainable, and well-documented code adhering to industry best practices and SOLID principles.
- Develop unit and integration tests using JUnit 5, Mockito for backend, and Jasmine/Karma or Jest for frontend to maintain high test coverage.
- Participate in code reviews, CI/CD pipeline automation (GitLab CI, GitHub Actions, Jenkins), and containerized deployments using Docker.
