The work will require pulling together COTS and custom components across RF, compute, data handling, sensing, power, wiring, and command-and-control interfaces; integrating those components into a larger aircraft or mission system; and producing architectures that are simple, inspectable, maintainable, and credible to internal engineering teams and external stakeholders. Deep practical understanding of one or more avionics-relevant subsystems, such as command and data handling, RF communications, LOS/BLOS data links, embedded compute, power management, sensing, wire harnessing, or aircraft electrical integration.
