Requirements

Requirements, Knowledge, Skills and Abilities:

  • Ph.D. in Chemical Engineering, Biomedical Engineering, Chemistry, Pharmaceutical Sciences, or related discipline with 6-plus years of relevant, post-graduate, lipid nanoparticle (LNP) formulation experience
  • A minimum of 4-years’ experience in generating LNPs in a preclinical industry setting using state-of-the-art manufacturing methods like advanced microfluidics, T-mixing, and tangential flow filtration (TFF) is a must
  • Strong experience in preparing and characterizing LNPs for in vivo applications as demonstrated through publication record, patent filings, and/or work in a relevant drug development setting is required
  • Familiarity with approaches used to target LNPs to different tissues/cell types in vivo is preferred
  • Experience using design of experiment (DoE) and relevant statistical software packages (JMP) for formulation discovery is preferred and may be considered in lieu of extensive, practical nucleic acid formulation experience
  • Hands-on expertise in basic analytical and biophysical methods used for the characterization of nanoparticle formulations, particularly size, morphology, zeta potential, and nucleic acid encapsulation/release (i.e., DLS, fluorescent assays, HPLC/UPLC, etc)
  • Familiarity with in vivo pharmacology and ADMET concepts as they relate to nucleic acid nanoparticle drugs
  • Experience using predictive data analysis, computational methods/software, and machine learning for formulation and/or drug discovery is a plus but not required
  • Established track record of supervising/mentoring junior researchers
  • Must be self-motivated and experienced in optimizing and advancing LNP formulations within a multidisciplinary team environment with scientists and external collaborators


Salary Range for Senior Scientist: $122,850 to $179,025

Salary Range for Principal Scientist: $148,500 to $187,000

The final salary offered to a successful candidate will be dependent on several factors that may include but are not limited to the type and length of experience within the job, type, and length of experience with the industry, education, geographic location, etc.
