Brian Del Gaudio · Cybersecurity Engineer → AI Evaluation & Safety

I'm a cybersecurity engineer with 8+ years securing U.S. Space Force and DoD aerospace systems, and for the last two years I've been evaluating large language models on the side. Now I'm going all in on AI — aiming at safety & evaluation work at a frontier lab.

By day I'm the lead cybersecurity engineer for a program office in the U.S. Space Force's Innovation & Prototyping Delta, where I oversee cyber engineers across several contractor teams and guide prototyping programs and space vehicles through RMF and ATO. Before that I spent six years on the GPS Directorate, where I helped achieve an ATO in a record five months that enabled a first-of-its-kind tactically responsive space mission — built and launched in under a year.

About two years ago I started doing AI evaluation and RLHF work on the side: ranking and critiquing model outputs across reasoning, writing, health, and open-ended tasks, and writing the rubric-based rationales that feed back into training. As a cybersecurity subject-matter expert I was pulled onto specialized projects grading models on offensive and defensive security tasks — penetration-testing workflows, secure code review, incident response — scoring each step for technical accuracy and safety.

That led to a contract on a frontier lab's safety & trust team, reviewing real-world attempts to misuse frontier models for cyber operations and adjudicating them against usage policy. My offensive-security background turned out to be exactly the lens that work needs — telling a legitimate, educational, or defensive request apart from genuine attacker intent, where both false positives and false negatives carry real risk.

That experience is what convinced me to pivot. I want to do this full time — help make models more capable, and help make sure they stay aligned, safe, and a benefit to humanity rather than a threat to it. This site is me building toward that in the open, from the math up. Read my full story →
