RF Test Engineer

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 an RF Test Engineer, you will develop the hardware, procedures, and automated test infrastructure used to validate Array’s radar payloads and satellite electronics. Your work will include designing test fixtures and harnesses, creating FPGA- and software-driven test interfaces, developing board- and system-level test plans, and executing environmental and functional testing across a range of operating conditions.

You will collaborate closely with electrical, RF, antenna, mechanical, and manufacturing engineers to diagnose issues, validate performance, and ensure flight readiness. The test systems you build will directly affect hardware reliability, calibration stability, and overall system performance on orbit. As part of our quickly growing engineering team, you will play a critical role in the design of the world’s most advanced radar satellite constellation—one that will significantly improve humanity’s ability to rapidly and comprehensively understand our changing planet.
