Senior Scientist - Reagent Design

The Senior Scientist – Reagent Design performs a broad range of scientific activities spanning research, new product development (NPD), reagent manufacture, process transfer, and product support. Working within a technically focused R&D team, this role combines bench‑level experimental rigor with cross‑functional collaboration to advance veterinary diagnostic products from concept into production.

• Design and execute experiments to support new reagent development, including hypothesis generation, execution, data analysis, and results reporting.
• Contribute to multi‑disciplinary NPD project teams, applying deep scientific expertise to define and solve complex technical problems.
• Develop and refine assay components, reagent characterization, reagent production, conjugation chemistry, and particle preparation.
• Learn and apply IDEXX NPD processes, including document creation and management.
• Provide technical solutions to NPD challenges, generate written reports and summaries autonomously, and communicate findings through presentations.
• Prepare solutions and reagents; execute standard laboratory protocols with consistency and accuracy.
• Perform scientific procedures such as bio‑conjugations, conjugate purifications, particle functionalization, raw material qualification, reagent design verification, and analytical method development for reagents.
• Analyze and interpret complex or ambiguous data sets, make evidence‑based recommendations, and lead reagent design risk assessments.
• Document reagent process flows and transfer knowledge to Process Development teams, including materials used in design assessments, training plans, process maps, functional diagrams, analytical methods, and design decision rationales.
• Support the development, maintenance, improvement, and mechanistic understanding of existing products and reagent production processes; provide troubleshooting and root‑cause analysis.
• Provide technical answers to product support problems and participate in investigations involving field or manufacturing issues.
• Provide guidance, coaching, and basic mentoring to junior scientific staff; may supervise others.
• Lead project teams and project programs that may span multiple scientific disciplines within the R&D organization.
• Build and leverage a network of internal and external scientific contacts to inform work and drive solutions.

• Doctor of Philosophy (PhD) or equivalent combination of education and experience in organic chemistry, biochemistry, molecular biology, analytical chemistry, or related field with 0–3 years of industrial experience.
• PhD, Master’s, or Bachelor’s with corresponding years of relevant industry experience as specified:
  Master’s with 8+ years, Bachelor’s with 10+ years in IVD, diagnostics, or related product development environment.
• Demonstrated hands‑on laboratory experience in protein biochemistry, immunoassay development, or related reagent sciences.
• Proven ability to independently design experiments, analyze data, and communicate results in written and oral formats.
• Strong problem‑solving skills and ability to address complex, non‑routine challenges.
• Experience with conjugation chemistry, antibody/antigen production, biologics characterization, bio‑conjugate purification, and/or functionalized particle preparation and characterization (preferred).
• Familiarity with regulated product development environments and associated documentation requirements (preferred).
• Experience with veterinary diagnostics or animal health product development (plus).
• Strong data analysis experience, familiarity with Six Sigma and similar methodologies, proficient in the use of statistical analysis tools such as JMP.
• Strong project management experience and proficiency with project management tools.
• Strong written communication skills; experience generating technical reports and SOPs.

• Salary range starting at $105,000 based on experience.
• Opportunity for annual cash bonus.
• Health, dental, and vision benefits available from day one.
• 5% matching 401(k) plan.
• Additional benefits including pet insurance, mental health resources, volunteer paid days off, employee stock program, foundation donation matching, and more.
