Topos Bio

At Topos Bio, we're pioneering drug discovery for intrinsically disordered proteins—targets that have eluded conventional approaches in neurodegeneration, oncology, and cardiometabolic disease.

We're seeking a cell biologist to develop and execute cell-based assays for validating computational predictions and supporting medicinal chemistry efforts. You'll work at the interface of disease biology, protein biophysics, and drug screening.

What you will do
  • Develop and optimize mammalian cell-based assays for disordered protein targets

  • Execute phenotypic and reporter-based screening campaigns to validate computational hits

  • Characterize compound activity and support structure-activity relationship studies

  • Collaborate with computational scientists to integrate experimental data with modeling workflows

  • Establish robust assay protocols and quality control metrics

What we are looking for
  • Strong foundation in mammalian cell culture and cellular assay development

  • Experience with disease-relevant cellular models

  • Ability to troubleshoot complex biological systems and optimize experimental protocols

  • Track record of productivity and effective collaboration

Preferred
  • PhD in cell and molecular biology with focus on disease models

  • Industry experience in drug discovery or biotech

  • Experience with reporter assays and high-throughput screening platforms

  • Familiarity with oncology, neurodegeneration, or metabolic disease models

  • Track record of developing novel cellular assays or screening approaches
