Security Engineer

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.

Your Role

We're looking for an experienced, hands-on Security Engineer to secure XBOW's product, cloud, and platform as we scale. This is a technical individual contributor role focused on building security into how we design, ship, and operate systems.

You'll work closely with engineering and platform teams across application security, cloud security, vulnerability management, and incident response. The core of this role is security engineering ownership: improving preventive controls, detection quality, and response readiness, while driving remediation of real risks in production.

What You’ll Do

• Design and implement security controls across cloud, infrastructure, and internal platforms
• Partner with engineering to harden cloud architecture, IAM, and infrastructure
• Own product security reviews for new features, services, and major architecture changes
• Drive threat modeling and secure design decisions early in the SDLC
• Operate and improve AppSec workflows (SAST, SCA, secrets scanning, IaC scanning)
• Triage vulnerabilities across application, container, and cloud findings, and drive remediation with risk-based SLAs
• Define and run the vulnerability management lifecycle: intake, prioritization, exception handling, validation, and reporting
• Improve CNAPP coverage and finding quality across cloud accounts and workloads
• Improve Kubernetes and container security posture
• Monitor, investigate, and respond to security events and incidents
• Build automation to improve security operations, access workflows, and incident response
• Support the compliance function by implementing and maintaining technical controls for SOC 2 and ISO 27001, and by documenting security processes, playbooks, and policies that scale with the company.
• Support the IT team with timezone coverage for core operational security tasks, including SaaS administration (Okta, Google Workspace, 1Password), onboarding/offboarding workflows, and endpoint access management (MDM, VPN, and secure device provisioning) for a fully remote team.
