Senior Associate Scientist - Therapeutic Antibodies

The Late-stage ELISA Support (LES) group under the Pre-Clinical Antibody and Assay Development (PAAD) team executes potency assay development and analytical testing to support lead molecule development from Pre-IPA through BLA. The team develops fit‑for‑purpose assays, supports clinical and regulatory programs, and partners with internal drug development, manufacturing, and quality control stakeholders to enable drug substance (DS), drug product (DP) through stability and IV admixture testing, among other sample studies.

Responsibilities during a typical day might include the following:

• Perform potency testing of manufacturing, QC, and stability samples.
• Design, develop, and optimize binding and blocking ELISAs to support potency testing of lead protein therapeutics across research and clinical programs.
• Analyze and interpret data using GraphPad Prism and Excel; clearly summarize results for stakeholders.
• Maintain accurate, thorough laboratory documentation and data records, performing internal QC checks for team members.
• Prepare data summaries and presentations for internal reporting.
• Communicate project status and results effectively in written and verbal formats.
• Demonstrate strong attention to detail, as assays developed are used for clinical testing and regulatory documentation; prior experience in a GLP environment is a plus (role is non‑GLP).

This role may be for you, if you:

• Bachelor’s or Master’s degree in a scientific discipline with typically 2+ years of relevant laboratory experience (Demonstrated expertise in ELISA‑based immunoassays is highly preferred)
• Strong understanding of drug–ligand binding principles, with the ability to apply concepts to assay development and troubleshooting. This role is primarily lab-based.
• Proficient in Excel and PowerPoint for data analysis and presentation; experience with GraphPad Prism preferred.
• Proven ability to independently analyze, interpret, and summarize complex data with a high level of accuracy.
• Exceptional attention to detail, recognizing that assays developed by our group support clinical testing and regulatory documentation.
• Strong time‑management, organizational, and multitasking skills, with the ability to manage multiple projects in parallel.
• Ability to work independently with minimal supervision, while contributing effectively in a collaborative, team‑oriented environment.
• Strong written and verbal communication skills, including experience presenting data to cross‑functional stakeholders.
• Prior experience working in a GLP or regulated laboratory environment is a plus, though the role itself is non‑GLP.
