About the role

Posted Sep 11, 2026

The role: BigHat Biosciences is looking for a hands-on, bench-driven scientist to perform IND-enabling developability assessments on late stage drug candidates from our Milliner Platform for AI-designed therapeutics. This is a lab-based 12-month contract role, with the possibility but no guarantee of conversion to full-time position. You'll spend the majority of your time at the bench executing complex stability studies.
  • Lead, design, and execute in-use dose solution studies to assess drug compatibility with administration materials.
  • Develop highly sensitive protein characterization methods (qSEC, RP-HPLC, CEX, particle counting, etc) for assessing drug quality and recovery.
  • Support late-stage characterization, including formulation screening, stress testing, and peptide mapping, to rank and advance lead candidates.
  • Drive developability assessments (purity, stability, tolerability, biophysical properties) across programs, with strong attention to data interpretation and organization.
  • Communicate with and manage external CROs for testing and analytics.
  • Interpret and communicate scientific findings, propose next steps, and broadcast clearly across the organization.
  • Proactively identify and scope state-of-the-art analytical tools and developability technologies.
  • PhD in Biochemistry or relevant discipline with 5+ year(s) of industry experience; exceptional non-PhD candidates with deep bench experience will be considered.
  • Experience developing and optimizing sensitive analytical chromatography-based methods is a must.
  • Strong background in biophysical and analytical characterization of antibodies and antibody fragments: SEC, HIC, CE-SDS, DLS, DSF, ELISA, LC-MS.
  • Track record of translating complex data into clear results and recommended actions.
  • Enthusiastic about learning and onboarding new technologies to expand capabilities and improve work quality, timelines, throughput or cost.
