This position requires effective communication and documentation of results that enable the advancement of novel research molecules toward development candidates and in IND-enabling stages. Ideal applicants will be collaborative and team-oriented, possess excellent communication and organizational skills, and carry a strong commitment to excellence.

Education and Experience requirements:

  • PhD with 5+ years of relevant pharma or biotech industry experience in cellular immunology, immuno-oncology, or a related field.
  • Ability to lead cross-functional groups (internal and external) to execute nonclinical IND-enabling programs and author relevant sections in regulatory filings
  • Experience with early biomarker discovery and PK/PD assessment utilizing IHC, flow cytometry, CyTOF, RNAseq, and bioanalytical PK/ADA assays.
  • Experience or knowledge of requirements for IND filings is preferred.    
  • Experience in managing and mentoring PhD scientists and research associates.
  • Experience working with CROs and academic partners
  • Experience with T cell engagers and an in-depth understanding of T cell biology is desirable.
  • Knowledge of protease biology is a plus.
  • Experience with ex vivo tumoroid/organoid cultures is a plus.
