Description

We are seeking a motivated, highly collaborative, and technically versatile Principal Scientist to help build FL132’s amyloid research platform from the ground up. This is a hands-on role at the interface of protein biophysics, chemical biology, structural biology, and neurodegeneration.

Key Responsibilities:

  • Contribute to scientific and technical direction in collaboration with FSP leadership to shape company strategy.
  • Establish in-house production and quality control of assay-grade recombinant amyloid proteins.
  • Design and analyze amyloid aggregation experiments.
  • Characterize amyloid aggregates via mass spectrometry, NMR, AFM, or related methods.
  • Support the build of cell-based assays for evaluating amyloid toxicity, seeding, and clearance.
  • Evaluate inhibitors of amyloid aggregation and translate findings from biochemical systems into cellular models.
  • Scope, contract, and manage CROs and academic collaborations.
  • Drive key project goals, ensure rapid, accurate turnaround of data and translate experimental results into insights.

Required Qualifications:

  • Ph.D. in structural biology, chemical biology, biochemistry, biophysics, physical chemistry, or a related field, with 8+ years of relevant industry or postdoctoral experience.
  • Hands-on recombinant protein expression, purification, and QC.
  • Deep expertise with kinetic assays of protein aggregation.
  • Familiarity with amyloid aggregation mechanisms and strain/seeding biology.
  • Motivated team-player and effective independent contributor with strong organizational and written/verbal communication skills.

Preferred Qualifications:

  • Experience with structural characterization of proteins and aggregates using mass spectrometry-based approaches.
  • Familiarity with cryo-EM, atomic force microscopy (AFM) or NMR.
  • Experience with statistical design of experiments (DoE) and the analysis of large, time-resolved kinetic datasets.
  • Experience managing contract research organizations (CROs).
  • Familiarity with cell-based neurodegeneration assays.

What we can offer you:

  • Opportunity to lay the scientific foundation of a transformative platform company as an early employee.
  • Custom-tailored role to maximize impactful contributions, professional growth, and scientific interests.
  • Monthly social events, and community lunchroom with free snacks, coffee.
