Director of Software Engineering

Radical AI is replacing an R&D process that currently takes 10+ years and $100 million to produce a single discovery. Our self-driving lab platform combines AI with autonomous robotics to run experiments, analyze results, and iterate—continuously, without human bottlenecks. For industries like aerospace, automotive, defense, energy, manufacturing, semiconductors, and space, that means breakthroughs in weeks instead of years. We're a small, senior team, growing fast. This is a foundational hire. The Role We're looking for a Director of Software Engineering to build and lead the software engineering team as we scale. This is a player-coach role in the truest sense: you'll ship code every week while also owning the team's growth, culture, processes, and long-term technical direction. You'll report to our President and Co-Founder, and work closely with cross-functional stakeholders across science, hardware, and product. The immediate mandate is to stabilize and grow a talented but lean team during a period of rapid hiring and technical expansion — including near-term customer deployments that involve significant architectural challenges. This is not a role for someone who wants to delegate the hard technical problems. It's for someone who wants to be in the middle of them.
