Full-time /
On-site
At Until, we believe human whole-body reversible cryopreservation is within reach. We’ve assembled a world-class multidisciplinary team, secured $48M in funding, and are pushing the frontiers of biology, chemistry, engineering, and physics to develop groundbreaking cryopreservation technologies.
Our current focus is an advanced transplant organ protocol that will enable indefinite organ storage, ensuring every donated organ can save a life. Ultimately, whole-body reversible cryopreservation will allow patients to pause biological time until cures for fatal diseases exist. Joining our founding team means contributing to an ambitious scientific mission with infrastructure, engineering talent, and operational support far beyond what’s possible in academia.
About the Role
We are seeking an experienced, highly skilled Histologist—at the level of a senior research associate, scientist, or PhD-trained researcher—to lead histology assay development for evaluating mechanical and toxic damage in tissues following cryopreservation.
In this role, you will (1) design and implement histology assays from the ground up, selecting appropriate methodologies based on scientific needs, (2) collaborate with pathologists to generate high-quality, interpretable tissue health reports. (3) integrate additional molecular biology techniques such as western blotting and qPCR into the tissue processing pipeline, and (4) oversee tissue tracking, management, and processing, ensuring rigorous experimental data integrity from sample intake through imaging and quantification.
You will have the freedom to innovate, propose new approaches, and work across disciplines to improve our understanding of tissue health in the context of cryopreservation.
Key Responsibilities
- Lead the development and optimization of histology-based assays for tissue damage assessment.
- Collaborate cross-functionally with pathologists, molecular biologists, and engineers to design experiments that answer critical scientific questions.
- Manage end-to-end tissue sample workflows: labeling, tracking, processing, imaging, and archiving.
- Incorporate additional analytical methods (western blot, qPCR, immunohistochemistry) into the histology workflow.
- Ensure data quality and coordinate with the data science team for analysis and reporting.
- Survey literature and apply first-principles reasoning to identify and adopt novel histological and molecular techniques.
Qualifications
- PhD in a relevant life sciences discipline OR ≥3 years of hands-on histology experience with a proven record of independently selecting and implementing assays.
- Demonstrated expertise in histological techniques, tissue processing, staining, and imaging.
- Strong track record of method development and optimization based on research needs.
- Experience integrating histological data with molecular assays (e.g., western blot, qPCR).
- Excellent organizational skills and meticulous attention to sample tracking and data integrity.
- Preferred:
- Background in pathology or experience collaborating closely with pathologists.
- Familiarity with evaluating mechanical or toxic tissue damage.
Benefits
- A unique opportunity to apply your skills towards developing impactful technology and work with an ambitious team
- Medical and dental insurance coverage
- Flexible time off and paid holidays
- Competitive compensation package, including salary and equity
- Access to a 401(k) retirement savings plan
- Subsidized lunch daily
$95,000 - $125,000 a year
While this represents our expected range based on market data, final compensation will be determined based on your specific qualifications and may be outside this range. Please keep in mind that the equity portion of the offer is not included in this estimate.
