What does Liam Dowd do?
Most of Liam's week goes into trying to break things that are not meant to break. At Blue Goat Cyber he owns FDA premarket (524B) cybersecurity engagements end-to-end for medical device manufacturers, 16 devices so far with a 100% clearance rate to date. He embeds with customer engineering teams for months, with site visits in the U.S. and abroad, through testing, remediation, and the final submission. When something feels repetitive, his instinct is to automate it: he built the LLM-powered report writer that cuts report time from 10 hours to 2 and a customer-facing postmarket platform for continuous SBOM monitoring, and he manages a four-person international software development team. He also helps PRIA Healthcare make sense of messy regulatory data, and in his own time he keeps building products, most recently Sentinel.
How did Liam Dowd get to where he is?
Liam has been building since before it was a job. It started with iOS apps he shipped on his own, which grew into leading the small team behind Ember, a mental-health app that won the Congressional App Challenge and took him to the U.S. Capitol. From there the problems got bigger: software for mortgage underwriting, research into healthcare policy, and eventually security work on devices headed for the FDA. Today he studies computer science and business at Northeastern (3.95 CS GPA, Dean's List 2024-2026), with a stretch spent living and studying in London, and he holds CompTIA Security+ and the Hack The Box Certified Web Exploitation Specialist certification. Outside of work he travels — 34 countries so far.
