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.

• Own the day-to-day operation of Retro's histology workflows — managing work prioritization, quality control, and turnaround timelines 

• Independently 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

• Develop and document SOPs for all histology workflows, building up 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

• Have 5+ years of hands-on histology experience with FFPE workflows - embedding, microtomy, and staining

• Are proficient with both paraffin sectioning, cryosectioning, and vibrating sectioning

• Have experience with IHC and/or IF staining, including antibody titration and protocol troubleshooting

• Have demonstrated ability to work independently and manage multiple concurrent requests — you've been the go-to histologist that teams rely on

• Are naturally organized and detail-oriented - you keep clean records and a clean lab

• Communicate clearly and effectively - whether discussing tissue orientation with a scientist or coordinating things

• Are hands-on and proactive - you don’t wait to be told when something needs to be done

• Biotech, pharmaceutical, or academic research histology core environments

• Image analysis or digital pathology tools

• Training others on histology techniques

• GLP or regulated laboratory environments
