In addition to a competitive salary, we offer flexible working arrangements, 25 days’ annual leave, a generous employer pension contribution, life assurance, income protection, and private medical insurance.
At Waters, you will have opportunities to grow your career, expand your technical expertise, and contribute to products that make a meaningful difference in healthcare and clinical diagnostics.
Responsibilities
As a Principal Test Engineer, you will:
- Define and champion testing strategies, quality engineering practices, and validation approaches across multiple development teams.
- Design, develop, maintain, and execute manual and automated tests for clinical software products and platforms.
- Lead system-level testing activities for software-controlled LC-MS instrumentation and associated laboratory workflows.
- Collaborate closely with software, systems, hardware, and product engineering teams to verify end-to-end system behaviour, performance, reliability, and intended use.
- Drive continuous improvement in test automation, test infrastructure, tooling, and engineering processes.
- Investigate complex issues spanning software, instrumentation, data acquisition, and system integration.
- Act as a technical authority for testing approaches, engineering best practices, and system-level test strategies.
- Support risk management activities, defect investigations, and root cause analysis.
- Contribute to cybersecurity testing activities and help ensure products are developed with security and resilience in mind.
- Mentor engineers and testers, promoting best practices and fostering technical growth across the organisation.
- Work within a regulated quality management system to support the development of clinical and IVD products.
