Software Engineer, Developer & Research Platform

Build the platform that shortens the time it takes researchers and engineers to test ideas, ship software, and learn from experiments. We believe the software factory is just as important as the software itself, and you will build that factory for people and agents, including:

• Shipping the research platform where people and agents launch experiments, compare results, and decide what to try next.
• Designing systems that let coding agents take on more development, testing, and code review.
• Setting up better development environments, faster tests, and reliable deploys.

We look for strong systems engineering, developer taste, and a record of making other technical people more effective. You understand how researchers and engineers work, can go deep into the systems they depend on, and build tools they want to use.

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.
