This role is crucial for integrating Test-Driven Development (TDD) principles and ensuring code reliability from the ground up.

Key Responsibilities :

- Design, develop, and execute comprehensive unit test cases and test suites for application components written in Java, ReactJs, and Python.

- Utilize and maintain testing frameworks specific to each component:

- Java (Backend): Write unit tests using JUnit / TestNG and use Mockito / PowerMock for mocking complex dependencies and external service calls.

- Python (Backend/Scripts): Write unit tests using PyTest / unittest and employ mocking libraries like unittest.mock.

- Implement techniques like test doubles (Mocks, Stubs, Spies) to ensure tests are isolated, deterministic, and fast.

- Collaborate with developers to achieve high code coverage metrics without sacrificing test quality.

- Advocate for and help implement Test-Driven Development (TDD) and clean code practices (e.g., SOLID principles) within the development teams.

- Participate in code reviews to ensure new features and bug fixes are accompanied by robust unit tests.

Required Technical Skills :

Strong Proficiency in Core Languages :

- Python: Experience with Python for scripting and backend logic.

Tools & Methodologies :

- Familiarity with CI/CD tools (e.g., Jenkins, GitLab CI).

- Knowledge of an issue-tracking system like Jira.

- Understanding of code quality tools like SonarQube (or similar static analysis tools).

Required Qualifications :

- Bachelor's degree in Computer Science, Software Engineering, or a related field.

- Minimum 3+ years of experience as an SDET, Automation Test Engineer, or a Software Engineer with a heavy focus on unit testing.

- Proven ability to write clean, maintainable, and effective test code.

Preferred (Bonus) Skills :

- Experience writing Integration and End-to-End (E2E) tests using frameworks like Selenium, Cypress, or Playwright.

- Familiarity with containerization technologies like Docker.

- Prior experience in an Agile/Scrum development environment.

- Knowledge of cloud services (AWS, Azure, or GCP).
