Supplier Notes / Sourcing Guidance 

  • This is a 12-month contract position and is fully onsite in Alameda, CA. 
  • Hands-on LC-MS/MS experience is the primary non-negotiable requirement. Candidates should have direct experience performing LC-MS/MS bioanalytical work in biological matrices. 
  • Candidates with experience from CROs are strongly encouraged and should be prioritized for submission, particularly those with hands-on LC-MS/MS bioanalytical experience supporting drug discovery, DMPK, ADME, and PK studies. 
  • Recruiters should prioritize candidates with strong hands-on LC-MS/MS expertise and consider gaps in ADME, Phoenix WinNonlin, formulation, HRMS, or QTOF experience as trainable. 
  • Hands-on LC-MS/MS experience is the key requirement. ADME, Phoenix WinNonlin, HRMS, and QTOF experience are all valuable differentiators; however, candidates may be considered even if they do not have experience in every one of these areas.
