About the role

The enterprise security team protects the systems, identities, devices, and services that employees use every day. This role focuses on finding and prioritizing vulnerabilities, including novel ones and zero-days, across networks, endpoints, and SaaS, then driving fixes to verified closure. It also involves building automation and controls for AI agents. The posting says remote candidates in the U.S. are also considered.

What you'll do

  • Investigate and prioritize vulnerabilities and misconfigurations, including zero-days with incomplete information.
  • Turn technical findings into clear attack paths, business impact, and remediation steps.
  • Develop and validate emergency mitigations when patches are unavailable.
  • Coordinate with system owners, vendors, and incident responders to reach verified fixes.
  • Build security tools and integrations using code, APIs, automation, and AI agents.
  • Design controls for agent access, execution, and accountability, and support incident investigations.

Requirements

  • Experience independently investigating novel or emerging vulnerabilities and driving remediation to verified closure.
  • Technical depth in a relevant security domain with working knowledge of networks, endpoints, and SaaS.
  • Ability to read and improve code and safely integrate APIs and security systems.
  • Experience solving real problems with AI agents and evaluating their output.
  • Clear communication of technical risk to varied audiences.

The posting states no citizenship restriction. An employer like this or a U.S. agent can file, and approval depends on the individual's evidence.
