About Nightfall

See and control sensitive data across AI agents, MCP servers, endpoints, and SaaS — in real time. Legacy tools can't see this, let alone stop it. Backed by Pear VC.

About the role

A hands-on security research role with a public voice: the DevRel function for security operations and data security. AI models and agents give software new ways to access and move company data. We want someone who will test what that makes possible, find where data actually leaks, and show security teams what they found. Found on 1752vc Careers, the job board for startup and VC roles.

What they're looking for

  • 5+ years in security engineering, detection engineering, incident response, insider risk/DLP, security research or sales engineering
  • An established public voice in security: talks, a podcast, research write-ups, open-source projects or a following practitioners trust
  • You can code, work with APIs and debug across unfamiliar systems
  • You understand how enterprise data moves across SaaS, endpoints and AI tools, and how security controls like DLP, CASB, SIEM and EDR work
  • You can explain a technical finding clearly and defend it under questioning
  • You enjoy talking with security practitioners and engineers, on camera and in person
