About the Company:
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.
We’re looking for a highly organized, proactive, and mission-driven Executive Assistant & Office Manager to help keep our team and leadership running smoothly. This is a hands-on, on-site role reporting to our Head of Operations that blends day-to-day office operations with direct support for our C-suite.
You’ll be part of the connective tissue of the office—helping to create a productive, welcoming environment for the team while ensuring our executives are enabled to focus on high-impact work. This role is ideal for someone who thrives on ownership, anticipates needs before they arise, and takes pride in building systems that scale.
Provide high-touch administrative support to our C-suite, including: calendar management and scheduling across multiple stakeholders, meeting coordination and follow-ups, and arranging travel
Own day-to-day office operations in collaboration with Operations team members, including office layout and organization, grocery and office supply orders, etc
Jump in on special projects as needed—this role will evolve along with the company
Exceptional communication, organizational skills, and attention to detail
Strong sense of ownership and reliability; you follow through and get things done
Ability to anticipate needs and solve problems proactively
Comfortable operating in a fast-paced, evolving environment
High level of discretion and professionalism
Experience supporting senior executives or founders
Experience at a startup or high-growth company
Familiarity with tools like Google Workspace, Slack, Notion, etc.
We are building reversible cryopreservation technology to solve the organ procurement and matching problem.
Cryopreservation is already essential to modern medicine — powering IVF and life-saving stem cell therapies.
Now, we’re extending this technology to whole human organs — transforming hours of viability into weeks, or months, however long is necessary — so that no donated organ is lost to logistics, and no patient dies waiting.
By solving this immediate need, we de-risk and build the foundation for what comes next: whole-body reversible cryopreservation. We're pausing molecular motion to give patients a bridge to future cures.
