Lead avionics and Command & Data Handling (C&DH) within the Electrical Engineering team
Architect the avionics and C&DH subsystem, including buy-vs-build decisions
Own avionics and C&DH requirements, I/O and channel allocation, and interface control documents
Design in-house electronics, including topology, component selection, schematics, and circuit analysis
Perform worst-case and derating analysis and select EEE parts for a 15-year GEO mission
Support PCB layout, board bring-up, debugging, and testing

Work within the Systems Engineering baseline for requirements, interfaces, and technical budgets while owning avionics architecture decisions
Qualifications
B.S. or M.S. in Electrical Engineering or a related discipline; 8+ years, including spacecraft or other high-reliability avionics. Hands-on board design — circuits taken from requirements through schematic, analysis, bring-up and test, and you can show what you designed
Subsystem-level engineering: architecture definition, requirements flow-down, interface control and resource budgets
Command and data handling: on-board computing, telemetry and command architecture, data bus topology, and discrete, analog and serial signal accommodation
EEE parts selection and derating for space or another high-reliability domain
Specifying and technically managing procured electronics units, including supplier design reviews
Comfortable across electrical, software and systems boundaries, and able to reach agreement with subsystem leads
Strong plus: GEO communications satellites; FPGA or firmware familiarity; ECSS or equivalent space standards
Location:
Fully remote within the United States
Occasional travel to our Beaverton, OR office may be required for team meetings, integration, and other in-person work
