ML Research Engineer​/Scientist

Boltz is a public benefit company building the next generation of AI-powered molecular modeling tools to make biology programmable and accelerate drug discovery, while keeping frontier capabilities broadly accessible.

Boltz-1, Boltz-2, and Boltz Gen are open models trusted by 100,000+ scientists across biotech and academia, and used in programs at every Top 20 pharma as well as leading agrichemical and industrial research organizations.

We deliver these capabilities through Boltz Lab, our platform for running our latest models and design agents as reliable, production-grade tools. Boltz Lab is designed around real chemistry and biology workflows, so teams can start from a target and a hypothesis and quickly generate, evaluate, and rank candidate molecules. We provide the compute, the scalable infrastructure, and the collaboration layer, so scientists can iterate faster and stay focused.

You can read more about our mission, research and product vision on our manifesto.

As an ML Research Engineer/Scientist, you will develop the next generation of machine learning models and algorithms that power Boltz Lab and expand what scientists can do with AI in molecular modeling and design.

You’ll collaborate closely with an interdisciplinary team of ML researchers, domain experts in chemistry and biology, and software engineers. Together, you’ll design new model architectures, training objectives, and the high-quality datasets required to train them, pushing performance on fundamental tasks in drug discovery. You’ll also help define how we evaluate progress, building rigorous benchmarks and validation pipelines that connect offline metrics to real-world outcomes.

This role is for someone who is a mission-driven technical leader who wants to push the frontier and then turn that progress into capabilities that thousands of scientists can use. You’ll set direction as well as execute while holding a high bar on scientific rigor, strong engineering practices and real-world impact.
