Overview

Scientist leads biophysical characterization on Medra's Physical AI platform. Own label-free binding assays using SPR and BLI to create autonomous high-throughput workflows. Collaborate with roboticists and engineers to integrate assays and work directly with customers. Differentiate by blending deep biophysical judgment with hands-on automation expertise.

What You'll Do8

  • 1Develop validate and run SPR and BLI assays across formats including affinity kinetics epitope binning self-interaction and concentration quantitation on Carterra LSA and Gator BLI
  • 2Build biophysical capabilities end-to-end from scoping need to qualification writing SOPs and preparing validated workflows
  • 3Partner with roboticists to translate manual workflows into autonomous protocols covering sample handling plate setup and data pipeline integration
  • 4Create rigorous analysis frameworks for kinetics fitting binning heatmaps and developability flags to guide customer decisions
  • 5Integrate biophysical data with orthogonal characterization such as nanoDSF/DSC HPLC-SEC/DLS and AC-SINS for comprehensive developability insights
  • 6Work directly with customers to scope campaigns communicate results and translate scientific questions into assay plans
  • 7Maintain detailed ELN records and drive reproducibility across all deployed assays
  • 8Drive multiple workstreams simultaneously while resolving conflicts quickly and empathetically

Requirements7

  • 1Ph.D. in biochemistry biophysics structural biology or related with 2+ years industry experience or B.S./M.S. with 6+ years hands-on experience
  • 2Deep hands-on expertise with SPR and/or BLI including instrument operation assay development and data analysis
  • 3Strong command of binding kinetics theory including avidity mass transport regeneration and model selection
  • 4Proven experience developing and qualifying biophysical assays from scratch including method validation and troubleshooting
  • 5Understanding of antibody structure function and therapeutic antibody discovery process
  • 6Bonus experience with high-throughput SPR platforms array-based epitope binning VHHs bispecifics Fc-fusions non-Ig scaffolds lab automation platforms Python R
  • 7Track record of developing and qualifying new assays or platforms from scratch
