Executive Assistant & Office Manager
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.
About the Role:
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.
