About the role

  • This is a full-time, exempt, in-person position with work conducted at our Berkeley, CA location.
  • This range is for the SF Bay Area, California location and may be adjusted to the labor market in other geographic areas.
  • We celebrate diversity and are committed to creating an inclusive environment for all employees.

Responsibilities

  • Partner with sample prep and assay development to screen and select conjugation chemistries for peptides and oligonucleotides that enable single molecule protein sequencing
  • Design bioconjugation workflows using NHS-ester chemistry, maleimides, isothiocyanate chemistry, and click chemistry (CuAAC, SPAAC, IEDDA)
  • Develop labeling strategies based on Edman Chemistry
  • Develop and apply selective C-terminal and N-terminal conjugation chemistries
  • Develop site-specific labeling strategies for amino acid sidechains (Cys, Lys, Arg, Tyr, Trp, His, Asp/Glu) on native peptides. Screen protecting groups to enhance amino acid signal in the protein sequencing assay
  • Collaborate and document:
  • Work cross-functionally with sample preparation, assay integration, and reagent manufacturing teams to troubleshoot conjugation failures and optimize workflows
  • Maintain rigorous experimental documentation in Confluence and laboratory notebooks; author and maintain SOPs for new conjugation methods
  • Industry experience in bioconjugation chemistry, with demonstrated ability to independently design, develop, and troubleshoot conjugation workflows
  • Track record developing novel blocking groups and conducting SAR studies to optimize blocking group performance and selectivity

Requirements

  • MS/PhD with 8+/6+ years of experience (for Staff Scientist)
  • MS/PhD with 6+/4+ years of experience (for Senior Scientist)
  • Experience with site-specific amino acid sidechain chemistry beyond maleimide chemistry (e.g. Cys, Lys, Arg, Tyr, Trp, Asp/Glu) for application in multistep workflows
  • Proficiency in analytical characterization: HPLC method development, LC-MS/MS for conjugate analysis, UV/Vis, and CE

Nice to have

  • Hands-on experience with solid-phase peptide synthesis (SPPS), including protecting group strategies beyond standard Fmoc/Boc and selective on-resin modifications
  • Experience with peptide C-terminal chemistry manipulation methods: thioester formation, native chemical ligation, or photoredox/iridium-catalyzed C-terminal labeling
  • Familiarity with oligonucleotide chemistry and oligo-conjugation techniques (ITC, phosphoramidite modifications, click coupling to nucleic acids)
  • Experience with scalable surface chemistry methods for flow cells or solid-phase supports
  • Prior experience in an early-stage biotech or tools/diagnostics company
  • Navigates complex team dynamics, partnerships, and challenges with creativity and logic.
  • Operates with adaptability, urgency, and flexibility in evolving environments, thriving in ambiguity.
  • Treats obstacles as problems to be creatively solved, not reasons something can't be done.

Skills

  • Synthesize and purify peptide and oligonucleotide conjugates for assay testing
  • Characterize conjugation efficiency, purity, and stability using tools such as HPLC, LC-MS/MS, NMR, CE, UV/Vis, and FTIR
  • Learn from a diverse team of world-class scientists and engineers
  • Contribute to first-of-their kind technologies, high-impact publications, and patents

Compensation

  • Estimated Base Salary $123,000 - $187,575
  • This is the pay range for this position that we reasonably expect to pay.
  • Individual compensation is based on various factors including, experience, education, skillset, and geographic location.

Benefits

  • Employee Stock Option Plan
  • 100% Health Plan Coverage for Employees & Dependents (Medical, Dental, & Vision)
  • Employer Retirement Contributions to 401(k)
  • Generous Paid Time Off
  • Paid Maternity and Paternity Leave
  • Health & Wellbeing Program
  • To date, we have raised >$80M from venture partners and non-dilutive grant funding to achieve our vision of next generation proteome sequencing.
