Malachi Mabie
Software research engineer: AI/ML, robotics, systems
I work at whatever level the problem actually lives, from kinematics, data contracts, and failure traces up to product, strategy, and the culture of the team building it, and I move between them as the evidence calls for.
At Advanced Metal Research in Hawthorne I’m the learning and autonomy engineer on robotic welding. I built the team’s shared run-data platform, from the robot controller to queryable evidence, wrote its verification ladder from lint through weld-sample proofs, and built its agent software factory. Each run is bound to source revision, robot model, and calibration, so a result can be re-derived rather than trusted.
Before that I spent three years at RAM Laboratories, a defense SBIR research firm, becoming a senior member of technical staff. I was principal investigator on T-UEBA, a $250k Army SBIR in tactical behavior analytics, a named co-inventor on patent-pending automated vulnerability repair, and a core contributor to RAM’s DARPA AI Cyber Challenge entry.
Through Mabie Industries, my S-corp for startup work, I was Drone Institute’s sole engineer for six production services, and I’ve worked with Siethar Group, Hammies, and Truffle Computer Company.
I came up through robotics and manufacturing. FIRST Robotics led to Applied Medical at sixteen and five years of robotic tooling, fixtures, and automation for medical-device manufacturing that still run in production. I moved into ML and software to scale that work with tools, and studied cognitive science, machine learning, and neural computation at UC San Diego.
Selected work
- Robotic welding: shared run data from robot controller to queryable evidence, a verification ladder tied to merges and releases, an agent software factory, and Steam Deck operator controls at Advanced Metal Research.
- T-UEBA: temporal graph model for tactical behavior analytics. 95% accuracy, under 3% false positives, 400× smaller and 7.9× faster than the baseline.
- Automated code repair: DL-Patcher, patent pending as co-inventor, and core work on VULCAN, RAM’s DARPA AIxCC entry, where static analysis, fuzzing, and runtime verification judge generated patches.
- CAD from drawings: a work trial with Augrade; a geometry workbench that recovered 2,237 building polygons from about 67,000 CAD primitives.
- Production software: sole engineer for Drone Institute’s six services and their CI/CD, on serverless AWS at about $30 a month.
- Manufacturing tools: dozens of end-of-arm tools, fixtures, and tooling for injection molding, still running in production; one fix ended a $100k-a-month loss.
