AI Research Engineer

About us

We're reverse-engineering the origin of life - one of the great unsolved problems in science, and one we think AI finally makes tractable.

If we succeed, the applications are vast: from catalysis and green synthesis to ab initio synthetic biology and programmable matter. Understanding and harnessing these processes could let ten billion of us thrive on this planet - and let us dream that diverse life keeps evolving and thriving beyond it.

We're a small, diverse team of AI engineers, computational scientists, and bench scientists. We hold ourselves to the rigor of a research institute, but we ship like an engineering firm. Global team, HQs in Cambridge, MA and London, UK.

You'll design and train frontier models across biology and chemistry - molecular structure and dynamics, reactions, whole reaction networks. What your models predict decides what the wet labs run next; what the labs find decides your next model. We'll back an approach that might not work if the upside is large enough.

• Train large models across three threads: enzyme-substrate prediction, neural network potentials, and inverse design of reaction networks

• Own models end to end - architecture, data pipelines, training, debugging, evaluation

• Work directly with chemists and biochemists, and translate between the two fields fluently

• Fold new data into each iteration

• Demonstrated experience training large models end to end, with the depth to discuss in detail what broke and how you fixed it

• Strong ML engineering fundamentals: architectures, training dynamics, data pipelines, and evaluation

• Prior experience working directly on a chemistry, biology, or related physical-science problem, combined with the ability to communicate complex technical concepts clearly to colleagues whose first language is biology or chemistry rather than AI

• PhD in a quantitative field (common on our team, but depth matters more than credentials)

• Experience in ML-for-chemistry or ML-for-biology (e.g., neural network potentials, graph neural networks, protein or reaction models)

Compensation is highly competitive. We're also able to sponsor visas for the right candidate.
