Ratio is seeking a Research Associate / Senior Research Associate, Translational Pharmacology bench scientist to join our growing team. The successful candidate will execute biochemical and pharmacological assays to characterize reference and internal compounds. This role includes work in a laboratory environment involving research animals and radioactive materials, with appropriate training, safety protocols, and support provided. The ideal candidate will enjoy working in a collaborative, fast-paced, multidisciplinary environment.

Requirements

  • Bachelor’s degree in biochemistry, cell biology, pharmacology, cancer biology, pathology, or a related field
  • 0-5+ years of experience
  • Strong foundation in in vitro, ex vivo, or in vivo techniques (hands-on research experience preferred) but core competency in in vitro cell biology, in vivo pharmacology, or in vitro pathology is also considered.
  • Ability to communicate candidly and openly.

Nice To Haves

  • Experience using radioactivity in laboratory assays is a plus but not required as training will be provided.

Responsibilities

  • Execute translational pharmacology assays for compound evaluation, characterization and optimization.
  • Conduct ex vivo tissue experiments including histology, immunohistochemistry (IHC), and radiolabeled tissue analysis to characterize biodistribution.
  • Execute non-invasive in vivo pharmacology studies in cell line-derived xenograft models to include systemic dosing via intravenous and sub-cutaneous routes.
  • Support mammalian cell culture efforts and cell-based assays to advance discovery programs where required.
  • Maintain, troubleshoot, and evolve laboratory protocols and workflows.
  • Participate in daily lab operations—reagent tracking, ordering, and equipment upkeep.
  • Analyze, interpret, and present data clearly to internal teams.
  • Continue learning in radiopharmaceutical therapy and cancer biology.
  • Work collaboratively within and across teams in a complex, matrix environment.
  • Demonstrate strong interpersonal and organizational skills to leverage teamwork in creating innovative solutions and achieving common goals.
  • Continually learn and deepen expertise in radiopharmaceutical therapies and cancer biology.
