As a QA Engineer at Waters, your day-to-day responsibilities will center on ensuring the highest quality standards for advanced scientific software and systems. You will be embedded within an agile development team, working collaboratively to deliver reliable software releases.

Your primary deliverables will include designing, writing, and executing comprehensive manual and automated test plans. You will collaborate closely with Software Developers to understand feature implementations, identify potential edge cases, and ensure adequate test coverage. You will also work with Software Project Managers to align testing timelines with release schedules and provide transparent quality metrics to the Director of Quality.

In addition to feature testing, you will be responsible for maintaining and expanding the team's automated test suites, participating in code reviews for test scripts, and conducting detailed regression testing. When defects are found, you will perform root-cause analysis, document the issues clearly in tracking systems, and work with the development team to verify the fixes.

To be competitive for a QA Engineer position at Waters, you must possess a strong foundation in software quality assurance principles along with specific technical capabilities.

Technical Skills

• Must-have skills – Strong programming proficiency in C# (highly preferred for many teams) or Java, experience with test automation frameworks, and a solid understanding of manual testing methodologies.
• Nice-to-have skills – Familiarity with CI/CD tools, experience testing software-hardware integrations, and knowledge of relational databases and SQL.

Professional Experience

• Must-have experience – Proven track record of designing and executing test plans for complex software applications, and experience working within an agile software development lifecycle.
• Nice-to-have experience – Experience working in a regulated environment (such as medical devices, pharmaceuticals, or laboratory informatics) and familiarity with GxP or FDA compliance standards.

Soft Skills

• Must-have skills – Exceptional analytical and problem-solving abilities, strong verbal and written communication skills, and the ability to collaborate effectively with cross-functional teams.
• Nice-to-have skills – Leadership potential, stakeholder management experience, and the ability to influence quality practices across the broader engineering organization.

Q: What programming language is most important for the QA Engineer role at Waters? A: While many QA principles apply universally, many software teams at Waters heavily leverage C# and the .NET framework for their software stack and automation suites. While experience in Java is valuable, having strong C# experience can be a critical differentiator and is often required by specific hiring managers.

Q: How technical is the interview process for this role? A: The process is rigorous but balanced. You will face coding and automation questions, along with practical fault-finding or written diagnostic exercises. However, the team also places a very high value on your past experience, behavioral alignment, and communication skills.

Q: What is the format of the final round interview? A: The final round is typically a panel interview lasting around three hours. You will meet with multiple team members individually or in small groups, including developers, project managers, and quality leadership. This format allows the team to evaluate your skills from different perspectives and gives you a comprehensive view of the team culture.

Q: How does Waters view candidates with a background in manual testing who want to do automation? A: Waters values a strong quality mindset and analytical skills. If you have a solid foundation in manual testing and a strong desire to learn, you can be successful. However, you should be prepared to demonstrate basic programming logic and a clear understanding of automation concepts during the technical rounds.

To maximize your chances of success during the Waters interview process, consider the following strategic tips:

• Clarify the tech stack early: During your initial HR screening, ask which programming languages and automation frameworks the specific team uses. If they are looking for C# and your background is primarily in Java, take time to review C# syntax and framework equivalents before your technical round.
• Prepare for the panel dynamics: The final round involves multiple stakeholders. Tailor your answers to your audience; when speaking to a Software Developer, focus on code quality and technical depth; when speaking to a Software Project Manager, emphasize risk management, prioritization, and timely delivery.
• Practice structured fault-finding: Be ready to explain your diagnostic process step-by-step. Avoid jumping directly to a conclusion; instead, demonstrate how you systematically eliminate variables to isolate a defect in an integrated system.
• Highlight regulatory awareness: If you have experience working under GxP, ISO, or FDA regulations, make sure to highlight this. If you do not, research how software validation works in regulated environments to show that you appreciate the need for meticulous documentation and traceability.

A QA Engineer position at Waters offers an exciting opportunity to contribute to high-impact, high-precision scientific systems that make a tangible difference in global health and safety. The role combines deep technical challenges in test automation and system diagnostics with a highly collaborative, cross-functional team environment.

To prepare effectively, focus on solidifying your programming skills—particularly in C#—and practicing your structured problem-solving and fault-finding methodologies. Ensure your behavioral stories are well-structured using the STAR method, highlighting your adaptability, communication, and commitment to quality.
