Lead Software Engineer

Unit Test Design & Implementation :

- 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.

- ReactJs (Frontend) : Write unit tests for functional and class components using Jest and React Testing Library (RTL) to focus on user-centric behavior.

- 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.

Quality Assurance & Engineering Practices :

- 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.

- Integrate unit tests into the CI/CD pipeline (e.g., using Jenkins, GitLab CI, or GitHub Actions) to enable continuous testing on every code commit.

- Contribute to the overall automation and testing strategy, focusing on shifting quality left in the Software Development Life Cycle (SDLC).

Qualifications :

- Strong Proficiency in Core Languages :

a. Java : Solid understanding of OOP, data structures, and experience with Java-based unit testing.

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

c. JavaScript/TypeScript (for React) : Strong skills in modern JavaScript (ES6+).

- Testing Framework Expertise :

a. Backend : JUnit/TestNG (Java), PyTest (Python), and mocking libraries like Mockito.

b. Frontend : Jest and React Testing Library (RTL) is highly preferred.

Tools & Methodologies :

- Experience with Git and modern version control systems.

- 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).

- 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.
