In this role:

• You will lead development and optimization of biologics production processes to support new product development and lifecycle management initiatives.

• You will evaluate and implement technologies, methods, and approaches that improve reagent quality, process robustness, scalability, and operational efficiency.

• You will design and execute experiments, interpret complex data sets, and recommend data-driven technical decisions.

• You will contribute throughout the product development lifecycle, including feasibility assessment, process development, verification and validation activities, and investigations.

• You will collaborate closely with cross-functional partners including R&D, Manufacturing, Quality, Regulatory Affairs, Supply Chain, Program Management, and external partners.

• You will support preparation of technical documentation and regulatory submissions associated with biologics manufacturing and product development activities.

• You will serve as a technical resource and mentor to scientists and engineers across the organization.

• You will monitor scientific and industry developments and recommend opportunities to strengthen IDEXX capabilities and competitive position.

What you need to succeed:

• Ph.D. in Biochemistry, Molecular Biology, Cell Biology, Bioprocess Engineering, Chemical Engineering, Biological Engineering, or a related field with 0-3 years of relevant industry experience; or Master's degree in above disciplines with 8+ years of relevant industry experience.

• Demonstrated expertise in mammalian biologics process development, including experience with one or more protein production platforms is required.

• Experience supporting development, scale-up, transfer, and/or commercialization of biologics manufacturing processes in a regulated environment is required.

• Strong technical problem-solving skills with the ability to design experiments, analyze data, and develop practical solutions to complex challenges is required.

• Experience managing or leading technically complex projects involving multiple stakeholders is required.

• Proven ability to work effectively in cross-functional teams and influence decisions through scientific expertise is required.

• Excellent written and verbal communication skills, including technical documentation and scientific presentations.

• Proficiency with statistical analysis and scientific data interpretation.

• Experience supporting recombinant proteins, monoclonal antibodies, polyclonal antibodies, or other biological reagents is preferred.

• Working knowledge of veterinary biologics regulations or other regulated biologics development environments is preferred.

• Experience with process characterization, technology transfer, validation, or commercial manufacturing support is preferred.

• Familiarity with Quality by Design (QbD), Design of Experiments (DoE), and risk-based development approaches is preferred.

• Experience working with external partners, contract research organizations, or contract manufacturing organizations is preferred.

• Experience with data analytics or advanced modeling approaches applied to bioprocess development is preferred.
