Develops aging-focused therapeutics across programs.
Salary Range: 100000 to 115000 (Currency: USD) (Pay period: per-year-salary)
Retro develops therapies for diseases driven by the biology of aging. We focus on cellular reprogramming and autophagy to rejuvenate cell and tissue function with the ultimate aim of adding 10 years to healthy human lifespan.
We’re building a mission-driven team of accomplished and kind individuals who embrace our startup culture of rapid iteration, transparency, and versatility.
We are hiring a Histotechnologist to join Retro’s growing histology core, supporting multiple scientific programs - including our Microglia, Tissue Reprogramming, and Autophagy teams - performing FFPE and cryo-sectioning workflows from embedding through staining and imaging. You will work in a dedicated histology lab space and be a part of the Scientific Operations team - a close-knit group of dedicated, resourceful humans, handling all things labs, facilities, and logistics.
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
Have 5+ years of hands-on histology experience with FFPE and fresh-frozen workflows - embedding, microtomy, and staining
Are proficient with both paraffin sectioning and cryosectioning
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
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
Multiplex staining techniques
Start-up experience or more resource-constrained environments
GLP or regulated laboratory environments
Develops aging-focused therapeutics across programs.
Retro Biosciences develops therapeutics aimed at extending healthy human lifespan by addressing the cellular drivers of aging. The company runs three main programs—cellular reprogramming, plasma-inspired therapeutics, and autophagy—supported by single-cell multi-omics, computational biology, and lab automation to build a pipeline that targets aging mechanisms to prevent multiple age-related diseases. Revenue comes from developing and commercializing these candidates once they prove concept through research and clinical development. The company differentiates itself by focusing on root causes of aging rather than single-disease drugs, using diverse, technology-enabled programs with a balanced pipeline, and leveraging advanced analytics and automation to accelerate discovery. The goal is to extend healthy years of life by ten years and reduce the healthcare burden from aging-related diseases.
