Manage all flight qualification activities, including environmental test planning (thermal vacuum, vibration, shock, EMC), margin assessment, and final acceptance testing.
Own the transition to volume production, including manufacturability, testability, and customer-facing documentation.
Drive root cause analysis, anomaly resolution, and technical risk mitigation throughout development and test campaigns.
Prior role as a Responsible Engineer, Technical Lead, IPT Lead, or Chief Engineer on flight hardware.
Experience in high-frequency antenna design e.g. Ka band.
Experience mentoring less-experienced project engineers and design engineers in associated discipline.

Bachelor's degree or higher in Electrical Engineering or a related field.
9+ years of engineering experience in electronics hardware development.
Hands-on experience with related technologies such as active phased array antennas.
Expertise in antennas and board-level RF electronics.
Experience testing active antennas, including measuring EIRP and G/T.
Leadership experience, including mentoring or leading multidisciplinary engineering teams.
Strong knowledge of systems engineering practices, requirements flowdown, verification/validation, and configuration management.
Excellent communication skills with ability to present complex technical information to diverse audiences.
