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: Site Reliability Engineer (SRE), Automation, and Incident Response In this role, daily work centers on keeping XBOW’s production systems stable, observable, and resilient as the product scales. You’d be building and maintaining automated reliability tooling, covering monitoring, alerting, and self healing; while defining and tracking service level goals for both production and development environments.

The role involves close collaboration with infrastructure and feature teams to manage cloud systems through IaC, review architectural changes for reliability and capacity impact, and respond to incidents during local working hours as part of a “follow the sun model.”

When issues occur, you’d lead or contribute to root-cause investigations, analyze incident trends across the organization, and turn those insights into improvements that reduce future risk. You’d also help maintain internal and customer-facing status dashboards that clearly communicate system health and uptime.
