As a Senior Avionics Systems Integration Engineer, you'll own the integration of Avidyne avionics (e.g., IFD display systems, autopilots, ADS-B/TAS, and FMS/navigator products) into the broader aircraft system: power distribution, wiring harnesses, antennas, flight control interfaces, and airframe-level electrical architecture. Define aircraft-level integration requirements: power budgets, wiring harness specs, antenna placement and coaxial routing, connector pinouts, and data bus interfaces (ARINC 429, RS-232, CAN, Ethernet).
