Sr. Scientist, Sensor Chemistry

Reports To: Sr. Mgr, Sensor Chemistry

The Senior Scientist, Sensor Chemistry is a technical contributor responsible for evaluating, selecting, and optimizing materials that influence colorimetric sensor and overall system performance. This role applies materials science and chemistry expertise to polymers, films, membranes, reagents, dyes, and other process‑critical raw materials. This role lies at the intersection of materials science and chemistry.

The individual designs and executes experiments, analyzes complex data sets, and develops or applies computational tools to support material screening, product development, process improvement, verification, validation, manufacturing transfer, and technical investigations in a regulated environment. The role works independently and cross‑functionally, communicates technical findings clearly, and maintains high-quality documentation.

• Troubleshoot technical issues specific to the materials chemistry of the AST systems, record and report these issues cross‑functionally, and provide suggestions and resolutions for investigations.
• Brainstorm and test novel product development ideas based on high‑level objectives and latest research findings.
• Develop and apply computational tools, scripts, and/or statistical methods to analyze, visualize, and interpret large, complex data sets generated from experiments and manufacturing studies.
• Anticipate and mitigate technical risks or hazards associated with experiments, materials, and project plans.
• Support materials and/or chemistry‑related process improvements and help define tests or critical quality attributes needed to monitor product performance and quality control.
• Operate following product development process guidance: write detailed documentation, set requirements for new products, run verification on those requirements, participate in validation as required.
• Ensure compliance with regulatory standards (e.g., FDA, ISO) and comply with biohazard safety standards.
• Read, analyze, and interpret scientific literature, technical procedures, and regulatory guidance relevant to sensor chemistry and diagnostic product development.
• Participate in technical design reviews, product risk assessments, data reviews, and cross‑functional investigation meetings.
• Collaborate with other scientists and managers to optimize testing protocols and workflows within the lab.
• Perform all work in compliance with company quality procedures and standards.
• Perform other duties as assigned.

• Bachelor's degree required in Materials Science, Chemistry, or a closely related field
• 2 years of professional related experience in a regulated lab working in Product Development
• Materials Science, Chemistry, Biomedical Devices, or Product Development Post Doc experience will be considered as professional experience

• Advanced degree (Master's or PhD) in Materials Science, Chemistry, or a closely related field.
• 1+ year of iterative product development work.
• Experience using advanced statistical methods and tools such as JMP, Minitab, R, Python, MATLAB, or equivalent to analyze and visualize large, multivariable experimental or manufacturing data sets.
• Experience writing or adapting code to automate data cleaning, analysis, visualization, model fitting, or reporting.
• Experience screening and selecting materials, defining test methods or specifications, and optimizing material interfaces to balance product performance, manufacturability, reliability, and supply continuity.
• Experience in medical device, diagnostics, in vitro diagnostic (IVD), biotechnology, pharmaceutical, or other regulated product development…
