Associate Staff Scientist

Department: Microbiology
Reports To: Associate Director R&D Microbiology

As an Associate Staff Scientist in the Microbiology Department, you will play a key role in the development of innovative Antimicrobial Susceptibility Testing (AST) products for the VITEK REVEAL platform. Leveraging your scientific expertise, you will independently design, execute, and analyze laboratory studies that support assay development, optimization, verification, and validation activities. You will contribute to the design and development of high-quality products on time, within budget, and with a high degree of customer satisfaction. You may act as a team leader for new product development or current product improvement projects.

This role combines hands-on laboratory investigation with collaboration across multidisciplinary teams, including software and systems engineering, manufacturing, quality, regulatory, and product development functions, to support the successful development and integration of AST assays on the VITEK REVEAL platform. You will generate and analyze complex microbiological datasets, apply statistical methods to evaluate assay performance, and communicate findings that support data-driven product decisions.

In addition, you will contribute to the development, validation, and documentation of scientific methods, tools, and processes that support efficient and compliant product development.

Success in this role requires strong scientific problem-solving abilities, data analysis skills, effective communication, and the ability to work independently while contributing effectively within cross-functional teams.
