Research Assistant, Materials Chemistry (Nanoparticles)

About This Role

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 hiring an experienced, full-time Research Assistant to support nanomaterials synthesis, characterization, and implementation. You will work directly with our scientific team to create novel nanomaterials, ensure their reproducible synthesis and help scale to a manufacturable product.

Key Responsibilities

Synthesize nanomaterials using high pressure reactors.

Purify materials and prep them for secondary experiments.

Characterize the materials using in house analysis techniques.

Work with external centers for advanced characterization of the material.

Interface and work with external collaborators, CROs, or CMOs.

Create, document, and maintain organizational and purchasing systems for chemicals and special reagents.

Ensure on-time data reporting and accurate sample delivery.

Prepare equipment and supplies for experiments of a variety of modalities, and assist with laboratory consumables management.

Additionally, as your laboratory capabilities expand, you will have the opportunity to support a growing number of experiments, including but not limited to: Organ cooling/rewarming, assay design, cryoprotectant formulation, cryoprotectant discovery, medical Imaging, toxicology, etc. Prior experience performing these experiments is not required, however, general familiarity with most or all of these concepts is very helpful.

Required Qualifications

You’ve completed an undergraduate degree in STEM with 3+ years of relevant experience in materials science, chemistry, bioengineering or a related field (Industrial or Academic).

Creative, passionate about discovery, excited to push science forward.

Comfortable in a laboratory setting.

Experience doing materials synthesis.

Experience with multiple characterization techniques, including FTIR, NMR, TEM, etc.

Why Join Us

An opportunity to grow. Team members who have an outsized impact are advanced rapidly.

Excellent medical and dental insurance.

Flexible time off + paid holidays.

A generous stipend package for independent learning.

A competitive compensation package (salary + equity)

401(k)
