About XBOW Build the future of offensive security with XBOW. Attackers are already using AI to move faster than defenders can react—we’re creating the platform that puts security ahead in the arms race. Our AI-powered system autonomously discovers, validates, and even exploits vulnerabilities, giving organizations proof-backed results in hours instead of weeks.
Founded by Oege de Moor, creator of GitHub Copilot, and backed by Sequoia, Altimeter, and other leading investors, XBOW is applying cutting-edge AI to one of the world’s most urgent problems. In just over a year, our AI—built by a world-class AI team and legendary security researchers—has uncovered thousands of real-world zero-days across the software billions rely on, and achieved the #1 ranking on HackerOne’s global leaderboard.
We’re a team of builders, hackers, and researchers who thrive on solving problems others think are impossible. If you want to push the boundaries of AI, reshape how security is done, and join the group defining this new era of defense—we’d love to talk.
Your Role We’re looking for a Developer & Security Relations Programs Director to design, own, and scale the programs that connect XBOW’s research and technology with the global developer and security community.
This role sits at the intersection of Security Research, AI Engineering, Product Marketing, and Content, with a mandate to turn XBOW’s breakthroughs into trusted, credible, and high-impact external engagement. You’ll build programs that support vulnerability disclosure, community trust, researcher engagement, technical advocacy, and long-term ecosystem growth—while ensuring tight alignment with product and company strategy.
You’ll work directly with security researchers, AI engineers, and marketers to shape how XBOW shows up in the world: from coordinated disclosure workflows and researcher programs, to technical content, community initiatives, and developer-facing campaigns. This is a highly cross-functional role for someone who understands both hackers and developers—and knows how to earn their respect.
You’ll thrive here if you love building programs from scratch, enjoy working deep in technical detail, and care deeply about credibility, transparency, and long-term community relationships.
