💰 $85,000 - $145,000

Quality AssuranceSoftware EngineeringTechnologyIT

🎯 Role Definition

A Test Automation Engineer is a specialized quality assurance professional who bridges the gap between software development and quality control. This role is pivotal in ensuring the stability, performance, and functionality of software products by designing, building, and maintaining automated testing frameworks and scripts. They are not just testers; they are developers focused on quality, using their coding skills to create robust systems that automatically verify code changes. By embedding quality checks directly into the development lifecycle (CI/CD), they enable teams to release high-quality software faster and with greater confidence. This individual acts as a quality champion, proactively identifying potential issues, analyzing system performance, and driving best practices in testing across the entire engineering organization.

Core Responsibilities

Primary Functions

  • Architect, design, and implement scalable and maintainable test automation frameworks from the ground up for various platforms, including web, API, and mobile.
  • Develop, execute, and meticulously maintain a comprehensive suite of automated tests to validate functionality, performance, and reliability across all application tiers.
  • Integrate automated testing activities seamlessly into the CI/CD pipeline (e.g., Jenkins, GitLab CI, Azure DevOps) to enable continuous feedback and early bug detection.
  • Author complex and reusable test scripts using modern programming languages such as Python, Java, or JavaScript/TypeScript to simulate user interactions and data flows.
  • Perform in-depth analysis of automated test results, triage failures, and collaborate directly with development teams to investigate, debug, and resolve defects.
  • Design and execute automated API tests for RESTful and GraphQL services, validating endpoints for functionality, security, and performance using tools like Postman, REST-Assured, or custom HTTP clients.
  • Create and manage realistic and diverse test data sets required to achieve robust and reliable test coverage for a wide range of scenarios.
  • Champion and enforce quality assurance best practices, coding standards, and testing methodologies throughout the software development lifecycle.
  • Conduct thorough regression testing to ensure that new code changes or bug fixes do not adversely affect existing application functionality.
  • Participate actively in code reviews, providing constructive feedback on both application code and test automation code to enhance overall quality.
  • Develop and implement performance, load, and stress tests using tools like JMeter, Gatling, or k6 to identify system bottlenecks and ensure scalability.
  • Stay current with the latest industry trends, tools, and technologies in test automation and propose innovative solutions to improve testing efficiency and effectiveness.
  • Create clear, concise, and comprehensive documentation for test plans, test cases, automation frameworks, and testing procedures.
  • Collaborate closely with Product Managers, UX/UI Designers, and Business Analysts to understand requirements thoroughly and develop corresponding test strategies.
  • Mentor and provide technical guidance to junior QA engineers or manual testers on automation principles, tools, and techniques.
  • Set up and manage test environments, including configuration, deployment, and data setup, often utilizing containerization technologies like Docker.
  • Track and report on key quality metrics, such as test coverage, defect density, and pass/fail rates, to provide stakeholders with visibility into product quality.
  • Isolate, replicate, and report defects with detailed, easy-to-understand steps in bug-tracking systems like Jira, and verify fixes once they are implemented.
  • Extend automation frameworks to support new application features, technologies, or testing paradigms, ensuring the framework evolves with the product.
  • Troubleshoot and conduct root cause analysis (RCA) for complex software defects that are discovered in production or during the testing cycle.

Secondary Functions

  • Support ad-hoc data requests and exploratory data analysis to uncover hidden issues or usage patterns.
  • Contribute to the organization's overarching quality engineering strategy and technology roadmap.
  • Collaborate with business units to translate customer needs and business requirements into specific, actionable engineering and testing requirements.
  • Participate in sprint planning, daily stand-ups, and retrospective ceremonies as an active member of the agile development team.
  • Assist in evaluating and recommending new tools, technologies, and processes to improve the software development lifecycle.
  • Provide support for production deployments and participate in on-call rotations for critical quality-related incidents.
