Senior IT Engineer - Cybersecurity

About XBOW

At XBOW, we’re redefining the future of cybersecurity by building the world's first autonomous pentester, powered by AI. Today, the gold standard for securing software systems is human pentesters, but with the rise of artificial intelligence, we’re stepping up to scale offensive security to meet the ever-growing demand.

AI is transforming the landscape of both cybersecurity and cyberattacks. While millions of people without security expertise are creating software, bad actors are using AI to launch more effective attacks. XBOW fights back with AI-driven superpowers, enabling security teams to stay one step ahead.

What makes XBOW truly unique? Like human experts, it forges creative attacks, adapts its learnings, and continuously works to find vulnerabilities faster than anyone ever could. We’re not only simulating threats—we’re also finding and responsibly disclosing real-world vulnerabilities, ensuring organizations can fix issues before they’re exploited. XBOW isn’t just a tool; it’s a transformative force in the secure development lifecycle.

Backed by Sequoia Capital and a team that includes the creators of GitHub Copilot and GitHub Advanced Security, XBOW is not just keeping up with the times—we’re shaping the future of cybersecurity. Our mission is simple: to defeat the bad actors before they strike, using AI to revolutionize how we approach offensive security.

We’re building something that must be built, and we’re the team to do it. Join us in shaping the next frontier of autonomous security.
