Before making facility engineering my primary professional focus, much of my engineering career was spent supporting aerospace and defense systems.
That experience moved progressively from software into electrical hardware, integration, wiring, and electrical power.
Embedded Avionics Software
I began my engineering career as a software engineering intern with Northrop Grumman developing embedded software for avionics processors and later worked full-time as an embedded avionics software engineer.
Laboratory Hardware & Systems Integration
I later transitioned into laboratory hardware design and integration. A major effort involved reverse engineering, redesigning, building, and integrating a test system for a quad-redundant flight-control-computer system across multiple software-integration laboratories.
My work included electrical power distribution, wiring, mechanical assemblies, printed wiring boards, interface hardware, and selection of vendor equipment.
Aircraft Wiring Design
At Boeing, I led aircraft wiring-design activities on multi-phase upgrade efforts. The work included:
- wire size and type selection
- protective-device selection
- relays, switches, and connectors
- voltage-drop considerations
- multidisciplinary design coordination
- certification documentation
- technical-order and maintenance-manual wiring updates
Electrical Power Engineering
My aerospace work also included electrical-power engineering. Responsibilities included evaluation of available power-system capacity, preliminary studies of distribution-system modifications, generator-related architecture trade studies, and electrical power design for software/system integration laboratories.
