Director of Development and Chief Scientist / VP of Technology roles
About
Software engineering leader with 25 years directing the organization behind a commercially shipped real-time Linux product ecosystem, and 37 years of hands-on systems work overall. Deep technical roots in real-time kernels and embedded Linux, paired with a sustained record of delivering mission-critical software for defense, aerospace, and government customers, including Lockheed Martin, Raytheon, NASA, Draper Labs, Princeton Plasma, and UTC Aerospace.
Known for owning complex, multi-architecture product portfolios end to end and executing reliably over the long haul: 250+ production releases of RedHawk Linux and its ecosystem, on schedule, across two decades. Equally comfortable writing kernel code, integrating upstream distributions, running the release process, or presenting to customers and sales teams.
Currently exploring Director of Development and Chief Scientist / VP of Technology roles where hands-on technical ownership and long-horizon engineering leadership are both part of the job.
