About Until
Until is a moonshot company building a “pause button” for biology. Our near-term focus is organ-scale reversible cryopreservation: preserving donated organs at subzero temperatures without ice formation, then rewarming them uniformly for transplant. By solving this grand challenge, we’re laying the foundation for whole-body reversible cryopreservation, giving patients a bridge to future cures.

To achieve our goal, we are assembling an interdisciplinary team to develop perfusion systems, cryoprotectant formulations, and vitrification and rewarming hardware.

We envision a future where no transplantable organ is lost to logistics, and no terminal diagnosis is final because patients can safely wait for future medicine to arrive.

Role Description
We are seeking a Senior Lab Operations Lead to own the day-to-day management and scaling of Until Labs’ research facilities. This role is responsible for ensuring that a large, technically complex laboratory environment operates with high reliability, safety, and throughput.

As Until Labs grows, this role will also play a key role in operationalizing expanded lab facilities, including helping stand up and scale into a new space, ensuring continuity of research and readiness for large-animal and GLP-adjacent work.

Responsibilities

Serve as the operational lead for the move to a new lab facility, in close coordination with leadership, EHS, and external vendors & consultants
Translate experimental and program needs into facility requirements (space, power, ventilation, gas access, drainage, cold rooms, perfusion areas, BSL space)
Plan and execute lab move logistics: equipment relocation, reinstallation, requalification, and downtime minimization
Help define lab layout and zoning to support large-organ workflows, animal tissue handling, and clean/dirty separations
Support day-to-day operations for large-animal model work (e.g., porcine)
Coordinate with external large-animal facilities, CROs, and veterinary teams to ensure smooth experimental execution
Ensure lab processes are compatible with animal facility constraints, biosafety requirements, and chain-of-custody expectations
Help adapt internal protocols for work originating from or transitioning into large-animal environments
Partner with scientists and engineers to operationalize complex, time-sensitive experiments involving large organs and perfusion systems
Prepare labs, equipment, materials, and personnel for long, high-risk experimental days
Act as a stabilizing operational presence during critical experimental runs

Qualifications - Required

5+ years of experience in lab operations, research operations, or senior lab management
Direct experience supporting large-animal model research (porcine or similar strongly preferred)
Familiarity with large-animal research facilities, workflows, and constraints
Proven ability to support complex biological experiments
Experience operating labs during periods of growth, transition, or relocation

Qualifications - Strongly Preferred

Experience in standing up move into a new lab or research facility
Exposure to GLP, preclinical, or regulated research environments
Experience working alongside CROs, veterinary teams, or external animal facilities
Comfort with cryo-systems, perfusion systems, pressurized systems, or custom hardware-heavy biology

Benefits

Opportunity for outsized impact creating the future as an early team member
Generous medical, dental, and vision insurance coverage for employees and their dependents
Flexible time off and paid holidays
Competitive compensation package, including salary and equity
Access to a 401(k) retirement savings plan
FSA and commuter benefits
Subsidized lunch daily
