As a Software Test Engineer III, you’ll ensure the quality and reliability of our software products through comprehensive testing strategies. Working in an adaptable environment, you’ll collaborate with teams to validate software for mass spectrometers, electron microscopes, and other analytical instruments that help make the world healthier, cleaner, and safer.
You’ll participate in all phases of the software development lifecycle, from requirements analysis through final release. Your role includes designing and executing test plans, automating test procedures, documenting defects, and verifying resolutions. You’ll work closely with developers, product owners, and stakeholders to ensure our software meets the highest quality standards while supporting continuous improvement in our testing processes.
Role Overview
We are looking for a highly experienced Lead Quality Assurance Engineer with 6–15 years of software testing and quality assurance experience, with strong expertise in functional testing, regression testing, test case design, defect management, and User Acceptance Testing (UAT) support. The role also requires strong hands-on test automation expertise, including Squish GUI Tester for desktop GUI automation and Playwright with Python/Pytest for web, end-to-end, and regression automation.
The ideal candidate should have extensive experience validating complex enterprise applications, defining comprehensive test strategies, managing test execution, and ensuring high-quality product releases. The candidate will work closely with product owners, business analysts, developers, UX teams, and other stakeholders to ensure that software solutions meet functional, business, and quality requirements. The candidate should be able to define and evolve maintainable automation frameworks, select appropriate automation coverage, and integrate automated regression suites into CI/CD workflows.
