Software Engineer - Platform / Core Infrastructure - Americas

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 Software Engineer - Platform / Core Infrastructure who’s passionate about building scalable systems and solving hard problems in ambiguous environments. In this role, you’ll design and implement the complex distributed infrastructure that powers our core AI engine and distributed analysis systems, enabling XBOW to run seamlessly across multiple cloud providers (AWS, Azure, OCI etc.) and contexts (SaaS, on prem). This is a role for someone who sees infrastructure as a product, loves clean abstractions, and knows how to dig into performance issues across layers. You’ll join a high-trust, high-velocity team where your work will have an immediate impact on both developer experience and product performance. If you like being at the intersection of deep tech and real-world impact, you’ll feel right at home. WHAT YOU'LL DO - Design and implement infrastructure systems that scale reliably and securely, and
