Mid-Level Full-Stack Developer

Ready to elevate your development career by mastering a complex cloud platform from the inside out?

In this unique hybrid role, you'll take ownership of our test automation infrastructure while progressively learning our microservices architecture through hands-on test and feature development. This position offers a structured growth path toward becoming a proficient full-stack developer with deep technical and platform knowledge.

Your Journey

You'll begin by strengthening our testing and quality foundation, gaining insights into:

• How our microservices communicate through Google Cloud Pub/Sub,
• How our Angular frontend interacts with Spring Boot APIs, and
• How our AI-powered features work on the Cloudia Platform.
• As you build comprehensive test coverage, you'll gradually take on feature development responsibilities, evolving into a well-rounded full-stack developer with quality-first principles.

Responsibilities

Testing & Quality (Primary Focus – 70%)

• Design, implement, and maintain automated tests for our microservices using JUnit 5, Mockito, and TestContainers.

• Create unit tests for Spring Boot services and Angular components (Jasmine/Karma).
• Implement test fixtures and mock data generators for MongoDB-based services.
• Set up and maintain test environments using Docker and TestContainers.
• Track and improve test coverage metrics across backend and frontend codebases.
• Document testing patterns and best practices for the team.
• Identify and report defects, collaborating with senior developers to diagnose root causes.
• Participate in code reviews, ensuring testability and clean code practices.

Feature Development (Learning & Growth – 30%)

• Develop and maintain full-stack features under the mentorship of senior engineers.

• Implement API endpoints in Spring Boot following OpenAPI specifications.

• Build and integrate Angular components with backend APIs using HAL/HATEOAS patterns.
• Work with MongoDB for data persistence and queries.
• Contribute to AI-powered features using Vertex AI and Gemini models.
• Collaborate with cross-functional teams to deliver reliable, high-quality solutions.
