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.
Backed by Sequoia Capital and Altimeter, 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.
About This Role We're looking for a technical writer who is passionate about helping customers get the most out of our products. Our documentation philosophy is simple: reduce friction in the UI first, and when you can't reduce it any more, write content that gets users back on track as fast as possible. We also believe that documentation is a team sport where everyone has a role to play.
You'll be creating documentation for a technically sophisticated security platform. This means working with complex systems, offensive security concepts, and enterprise deployment scenarios—then making them accessible to practitioners who need answers quickly.
This isn't about maintaining a wiki or transcribing engineering notes. You'll be working directly with design, product, and engineering teams to test features, influence UI decisions, and build documentation systems that scale. You'll own content strategy across your domain and help establish how we document at XBOW.
What You'll Do
You'll work with people across all disciplines at XBOW to understand our products, our users, and their different use cases.
