Responsibilities

Develop mobile terminal architecture by working closely with sub-system engineers in electrical, RF, antenna, thermal, modem, DSP, ASIC, algorithm, firmware, modeling, and software

Design tradeoffs of various terminal architectures, including RF and performance simulations to support tradeoff decisions

Develop the mobility lab so aviation, maritime, and automotive terminals can be validated both in lab environments and with LEO satellites

Proactively engage with internal and external development partners on systems' hardware and software architectures and implementation

Ensure delivered work meets technical, functional, performance, regulatory, and business requirements

Perform in-field and on-orbit validation with satellites

Traveling up to 10% of the time, depending on project phases
