The Senior Flight Ops Technician is a senior, hands-on technical role supporting the development, testing, and operation of unmanned aircraft systems in Ukraine. The role bridges aircraft prototyping, hardware integration, HIL/ground testing, aircraft maintenance, and field flight operations, working closely with hardware, software, autonomy, and flight-test teams. The technician will build and modify prototype aircraft, integrate avionics and electrical systems, fabricate parts using 3D printing and other rapid-prototyping methods, and troubleshoot mechanical, electrical, communications, and system-level issues. They will also build, maintain, and troubleshoot HIL rigs and related test infrastructure, help establish and maintain a local prototyping and flight-operations lab, and support aircraft readiness and field testing. This role is best suited for a versatile, self-sufficient senior technician who can move seamlessly between the lab, aircraft, HIL environment, and flight-test site—rapidly solving problems and helping engineering teams get systems ready for test and flight.
