Array Labs builds advanced radar systems to help humanity understand and respond to changes across the physical world. We’re launching a coordinated fleet of radar satellites to create a high-resolution 3D map of the Earth – updated in real time – enabling faster, smarter decision-making for government and commercial organizations supporting disaster response, infrastructure resilience, and mission-critical geopolitical intelligence. We design and build our satellites end-to-end, producing the world’s most advanced earth observation satellites. Our fleet will deliver unprecedented levels of accuracy, coverage, and responsiveness to power critical insights precisely where they’re needed most. About the Job As a Senior RF Design Engineer, you will design and validate the RF electronics that enable Array’s radar sensors. Your work will include low-noise receive chains, high-power transmit chains, RF switching and protection, bias and control circuitry, and integration of transceiver and timing-critical RF subsystems. You will take hardware from schematic design through prototyping, bring-up, characterization, and qualification, working closely with antenna, mixed-signal, mechanical, and systems engineers. The RF hardware you develop will directly impact signal quality, sensitivity, output power, stability, and overall on-orbit performance. Responsibilities Develop advanced RF electronic subsystems, from architecture to manufacturing Work closely with RF systems, antenna, mixed-signal, mechanical, firmware, and test engineers to design and validate state-of-the-art radar sensor hardware Own RF subsystem definition and design trade studies, balancing noise figure, linearity, output power, stability, spurious performance, and power consumption Select components, capture schematics, and design complex RF assemblies including receive and transmit chains, switching networks, filtering, and protection circuitry Lead prototyping, hardware bring-up, debug, characterization, and test campaigns for RF electronics Rapidly iterate on and improve RF designs based on laboratory and environmental testing Provide technical leadership through design reviews, risk reduction planning, and mentorship of other engineers
