The Role

Mach Industries is seeking a Principal Flight Test Engineer to serve as a senior technical authority and mentor within the Flight Test organization. This role is responsible not only for the execution and strategy of autonomous flight testing but also for developing the next generation of flight test engineers through direct mentorship technical leadership and establishment of disciplined test practices.

You will report directly to the Head of Flight Operations and work closely with Systems Engineering GNC Autonomy Software Structures Propulsion and Safety leadership. You will define how Mach conducts flight testingestablishing standards processes and infrastructure consistent with industry best practices from leading autonomous aerospace and defense organizations.

You will own the end-to-end validation and verification strategy across ground and flight test phases spanning component-level subassembly and fully integrated vehicle testing. This includes defining test approaches consistent with recognized aerospace standards (ARP4754 DO-160G MIL-STD-810) while adapting them pragmatically to the nature of autonomous attritable defense systems required to complete the mission CONOP.

As a principal FTE you will guide how Mach evaluates flying qualities handling characteristics and autonomy-in-the-loop behavior leveraging established frameworks such as MIL-STD-1797 and FAA certification basis while developing novel test techniques appropriate for non-traditional configurations and autonomous vehicles.
