Software Development Test Engineer

high-quality unit testing

Key Responsibilities

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).

Technical Skills & Qualifications

Required Technical Skills

• Strong Proficiency in Core Languages:

• Java:

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

• Python:

   Experience with Python for scripting and backend logic.

• JavaScript/TypeScript (for React):

   Strong skills in modern JavaScript (ES6+).

• Testing Framework Expertise:

• Backend:

  JUnit/TestNG

   (Java), 

  PyTest

   (Python), and mocking libraries like 

  Mockito

  .

• 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).

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).
