Nightfall AI Security Advocate role at Nightfall AI involves hands-on security research and public communication. The role includes testing AI models for data leaks and creating technical content for security teams.

Responsibilities

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.
You might be a detection engineer, incident responder or insider-risk engineer who enjoys explaining your work. Or a security advocate, researcher or SE who wants more time to build. At Nightfall, you'll own technical investigations end to end and become a trusted public voice for the company with SOC, IR and data security practitioners.
Run "The Model Did What?" investigations. Test new models, agents and AI tools against realistic enterprise workflows. Find concrete data exposures, build working reproductions, and show where security controls hold or fail.
Explain it on camera and in writing. Open your laptop and walk through what happened. Turn findings into technical videos, blog posts and demos that SOC and data security teams want to watch and share, working with our content team.
Build open-source tools. Ship detections, scanners, labs and utilities that practitioners actually use. Document them, respond to issues, and maintain them after launch.
Speak and teach. Give talks at security and engineering conferences (BSides, Black Hat, DEF CON villages and similar). Run hands-on workshops where participants reproduce the problem and test a defense themselves.
Build the community. Host or join podcasts, livestreams and practitioner communities. Bring what you hear from security teams back to product and marketing.
Equip our sales engineers. Create realistic, resettable demo environments with synthetic data, plus the scenarios and documentation SEs need to run them on their own.
