App Scientist and System Senior Test Engineer Waters Material Sciences

As a member of the TA R&D Engineering team, you will support two key areas within R&D: (1) generating high-quality thermal analysis and rheology datasets for our data science pipeline, and (2) performing system-level testing of TA Instruments software releases. This hybrid role combines laboratory materials characterization with structured software quality activities, ensuring that the scientific workflows our customers rely on are accurate, reliable, and intuitive.

• Perform DSC, TGA, SDT, and rheology measurements on polymers, composites, pharmaceuticals, and other materials to build reference datasets.
• Develop, refine, and document experimental methods tailored to the needs of analytics, modeling, and algorithm development.
• Ensure high data integrity through consistent sample preparation, metadata capture, and quality checks.
• Work with Data Science and R&D teams to define experiment matrices that address data gaps.
• Analyze results and provide material behavior insights to guide model interpretation and parameterization.
• Design and execute functional, integration, and end-to-end workflow testing across thermal analysis and rheology platforms.
• Validate instrument control, data acquisition, file handling, and analysis workflows from a system-level perspective, considering interactions between hardware, software, and experimental methods.
• Work with the System Test group to develop and refine test plans, scenarios, and regression coverage for new features, bug fixes, and system integrations.
• Reproduce, document, and communicate software issues to engineering teams with clear supporting data.
• Maintain instruments, calibration standards, and testing records.
• Prepare clear summaries of experimental results and testing outcomes for cross-functional teams.
• Provide occasional support to Applications, Sales, or Customer Support teams with expertise on thermal and rheological behavior.
• Contribute to a culture of quality, documentation, and continuous improvement.

Qualifications

• Bachelor’s or Master’s degree in Materials Science, Chemical Engineering, Chemistry, Mechanical Engineering, or related discipline.
• 5+ years of Hands-on experience with thermal analysis and/or rheology.
• Strong experimental technique, attention to detail, and demonstrated ability to generate high-quality datasets.
• Ability to interpret thermal transitions, decomposition behavior, viscoelastic response, and related material properties.
• Experience working with scientific software systems, including evaluating workflows, identifying issues, and providing structured feedback.
• Strong written and verbal communication skills.
• Experience with TA Instruments platforms and TA software environments.
• Familiarity with software testing concepts, including functional, regression, and workflow testing, with the ability to apply these concepts in practice.
• Ability to design and execute test scenarios that validate end-to-end workflows and uncover edge cases or failure modes.
• Strong problem-solving skills with the ability to evaluate issues based on user impact, severity, and frequency to support release-quality decisions.
• Experience with scripting languages (Python, MATLAB) for data analysis or automation.
• Experience with system-level testing of integrated hardware/software products is a strong plus.
• Exposure to data science workflows, metadata standards, or structured experimental datasets.
