  • Effectively communicate experimental findings in oral, written, and visual formats.
  • Work independently and collaboratively in a multidisciplinary team environment.

Qualifications :

  • Masters or BS in relevant discipline with 5+ years of industry experience. Level will be based on experience.
  • Experience with in-vivo  studies, ideally involving LNP delivery and/or nucleic-acid based therapeutics in rat, mouse, and NHP.
  • Deep expertise in  ex-vivo  analytical assays such as ELISA, MSD, qPCR, ddPCR, FACS, etc.
  • Experience with histological tissue analysis (IHC/IF, ISH, H&E, etc.) including tissue harvest, embedding, sectioning, staining, imaging and image analysis.
  • Experience with various mouse and rat models of diseases is a plus.
  • Experience performing  in-vivo  procedures in rodents, including preparation and administration of therapeutics and collecting material (blood, tissue, etc.) for  ex-vivo  analysis is a plus.
  • Hands-on experience with flow-cytometry, including panel design, execution and analysis is a plus.
  • Strong communication and interpersonal skills.
  • Strong organizational, analytical, and problem-solving skills.
  • The successful candidate will be expected to demonstrate flexibility in supporting the accelerated timelines associated with data generation, analysis, and reporting for in vivo studies.
  • Ability to thrive in a fast-paced, multidisciplinary, and rapidly growing biotech environment.
