Histotechnologist

Support day-to-day histology operations by independently executing workflows - managing work prioritization, quality control, and turnaround timelines 

Partner with the histology lead and scientific teams to triage and schedule work across programs, communicating realistic timelines, flagging conflicts early, tracking sample throughput, and maintaining organized records

Perform tissue and organoid embedding, paraffin and frozen sectioning, vibratome sectioning, and slide preparation for multiple scientific teams

Conduct IHC and IF staining, including protocol optimization and new antibody validation

Perform H&E staining and special stains as needed

Support the development and documentation of  SOPs for histology workflows, continuing to build the institutional knowledge for Retro’s histology practice 

Operate and maintain standard histology equipment - embedding center, microtome, cryostat, vibratome, water baths, fume hood, and associated instruments

Coordinate with CROs for tissue processing and ensure quality of incoming processed tissues

Decalcify tissues as needed for bone or calcified samples

Assist with imaging of stained sections or coordinate with instrument engineers for imaging support

Manage histology supplies inventory, ordering, and lab organization

Provide guidance to scientists on tissue collection, fixation, and handling best practices to ensure downstream quality
