Mammoth Biosciences has an incredible opportunity for an innovative and motivated individual to join our expanding therapeutics team. The primary role of this Senior Scientist I/II will be to drive and execute the preclinical in vivo proof of concept and IND-enabling studies for Mammoth preclinical programs, providing technical leadership to the project teams from discovery through IND-enabling studies.

This role requires excellent communication skills, in-depth knowledge of preclinical in vivo pharmacology (tissue targeting, PKPD relationships, efficacy models, safety assessment, etc.), and the ability to design translational studies to support future clinical activities. In this role, you will represent the in vivo team on interdisciplinary project teams to define, build, and optimize our diverse portfolio of preclinical programs.
  • Identify, establish, and execute preclinical in vivo studies to support and advance Mammoth research programs.
  • Establish and maintain IACUC protocols, amendments, and SOPs. 
  • Coordination and oversight of in vivo studies conducted at external CROs.
  • Contribute to the discovery and preclinical pharmacology plans, including defining key milestones and decision points and timelines, identifying risks and mitigation strategies, study planning and execution, selection of therapeutic indications, and future IND filings
  • Develop robust data packages, author accompanying reports to support regulatory filings
  • Collaboration with project team members to coordinate research studies to meet project timelines.

  • Bachelor’s degree with minimum of 8 years of experience; Master’s degree with 6 years of experience, or PhD with 3 years experience in related field (Senior Scientist I)
  • Bachelor’s degree with minimum of 9 years of experience; Master’s degree with 7 years of experience, or PhD with 4 years experience in related field (Senior Scientist II)
  • Expertise with in vivo technical skills and experimental design and execution, including various routes of administration (IV, PO, IP, and SC), sample collection, and minor surgical procedures
  • Experience in the management of CROs, including evaluation/selection, setting up processes, and quality control

  • Communication and troubleshooting skills, attention to detail, and ability to work productively in a fast-paced environment
  • Ability to work as part of a team as well as independently with minimal to no supervision
  • Meticulous experimental record keeping
  • Prior experience with: Transgenic and humanized mouse models, Gene therapy or editing delivery with AAV and/or LNP
  • Cell culture (human, mammalian, and tumor cells), flow cytometry, histology, and/or other molecular biology experience

  • Company-paid health/vision/dental benefits
  • Unlimited vacation and generous sick time
  • Company-sponsored meals and snacks
