AI is reinventing life sciences the same way it reinvented software engineering, and our team is building that future. We train frontier models that learn the underlying foundations of biochemical structure and interaction. We pair this with a computational workspace to iterate on molecules from idea to medicine, helping scientists move faster and develop medicines beyond the reach of existing methods. We value diverse perspectives and are ready to find greatness in unexpected places. ABOUT THE ROLE Define and build the workspace that scientists use to develop new medicines. We believe tools like Cadence for electrical engineering and Photoshop for graphic design fundamentally changed how experts work by making complex work available on a computer. Molecular engineering deserves software of that caliber, and this category is yours to invent. - Work directly with scientists and model researchers to understand how they experiment and make decisions, then turn that understanding into software for working with models and agents. - Invent the core concepts and interactions for molecular design on a computer. - Prototype and ship these interfaces and tools, owning the work from early design through production code. ABOUT YOU We look for exceptional design taste, the engineering ability to prototype and ship, and a track record of distilling complex domains into simple products. You can get to the heart of a difficult problem without losing the details that matter. Familiarity with the scientific domain is a bonus, but not a requirement. We care more about what you’ve built and the design decisions behind it. WE OFFER The opportunity to work at the vanguard of AI research and frontier biology, with world-class people, on a mission that matters. We protect and promote a culture of high velocity and ownership. We compensate our team accordingly.
