Establish and manage the first in-house histology capability, performing FFPE and cryo-sectioning workflows from embedding to imaging. The role involves coordinating with CROs for tissue processing and providing technical guidance to scientific teams on tissue handling.
Requires 3-5 years of hands-on histology experience with proficiency in paraffin, cryo, and vibratome sectioning. Candidates must be skilled in IHC/IF staining and capable of working independently to manage multiple concurrent requests.
You’re a skilled bench histologist who takes pride in producing high-quality sections and stains. You’re comfortable working independently, juggling requests from multiple teams, and building workflows from scratch. You’re organized, detail-oriented, and proactive - the kind of person who keeps a lab running smoothly without being asked. You communicate clearly with scientists, understand what they need from their tissue, and can advise on best practices from fixation through imaging.
