Automated Antibody Engineering Scientist

The Reagent Discovery group in Discovery Tech Futures, R&D, is looking for a motivated Automated Antibody Engineering Scientist to join a team focused on developing high-throughput antibody workflows for the next generation of IDEXX diagnostics. The successful candidate will employ a broad range of molecular biology and biochemistry techniques – from gene design and cloning through antibody generation to provide validated reagents for downstream immunoassay development.

The ideal candidate will thrive in a dynamic, multidisciplinary, and collaborative environment.

At IDEXX, the ability to rapidly develop high‑quality antibody reagents is foundational to advancing pet health diagnostics. The Reagent Discovery team is the critical bridge between biomarker discovery and immunoassay development – and this role sits at the center of that pipeline. As a Scientist II, you will drive the molecular biology and antibody generation workflows that move novel biomarkers from target sequence to validated reagent, directly enabling new diagnostic tools for veterinarians and pet owners.

• Design and execute molecular biology workflows for antigen and antibody construct development, including primer design, PCR‑based cloning, site‑directed mutagenesis, and sequence verification.
• Develop and optimize recombinant expression constructs using mammalian, insect, or bacterial systems to support high‑throughput antigen production.
• Devise and execute antibody generation workflows, including platform selection, immunization or display screening, and hit confirmation.
• Perform protein and antibody characterization utilizing standard biochemical techniques including SDS‑PAGE, Western blot, ELISA, BLI, and analytical SEC.
• Develop and maintain automated liquid handling protocols to increase throughput and reproducibility across molecular biology and screening workflows.
• Collaborate with LC/MS and genomics teams to evaluate incoming biomarker targets and establish feasible antigen design and production strategies.
• Partner with downstream immunoassay development teams to communicate reagent performance data, define acceptance criteria, and meet delivery milestones.
