Responsibilities

Testing Software of Measurement Instruments: Plan and execute testing of software integrated with specialized measurement instruments, including devices for air flow, aerosol and dust monitoring, indoor/outdoor air quality, fluid dynamics, particle counting, biomedical testing, contamination control, and biohazard detection. Ensure reliability, accuracy, and performance of software controlling these instruments

Lead Automation Efforts: Take ownership of test automation strategy, planning, and execution for both instrument and application software. Design, build, and maintain robust, scalable automation frameworks using modern programming paradigms and best practices. Ensure automation plans are in place ahead of development work, and update tests, as needed

Metrics, Reporting, and Quality Transparency: Track and report test coverage, both manual and automated, per release and/or quarterly. Provide QA testing metrics, defect insights, and bug escapes to software leads, supervisors, and stakeholders. Continuously refine metrics to improve visibility into software quality

Collaboration and Stakeholder Communication: Maintain transparency of testing processes to stakeholders, including Software Teams, Product Owners, and Product Managers. Keep test plans, results, and TestRail data current, share with key stakeholders, and encourage cross-team collaboration

Develop Comprehensive Automated Tests: Create sophisticated automated tests covering API, UI, backend, integration, and end-to-end scenarios, using tools such as Cypress, Playwright, Appium, TestComplete, Bruno, and other industry-standard frameworks. Make tests modular, reusable, and maintainable

CI/CD Integration and Test Infrastructure: Integrate automated tests into CI/CD pipelines. Make architectural decisions for testing infrastructure and tools. Analyze test failures, contribute to build stability, and ensure automation is aligned with production-grade standards

Test Data and Environment Management: Implement advanced strategies for test data creation, anonymization, and maintenance, including synthetic data generation and database mocking. Design and manage test environments and test labs for both on-premise and cloud-based systems

Mentorship, Best Practices, and Innovation: Mentor and guide junior test engineers and QA team members, promoting automation best practices, reusable libraries, and continuous improvement across the organization. Stay current with emerging trends, tools, and methodologies in software testing, driving innovation and maintaining relevance in the field
