Senior FPGA Engineer

About Us
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 FPGA Engineer, you will develop the FPGA logic and embedded software that drive Array’s radar payloads and on-orbit processing systems. Your work could include designing FPGA modules for high-throughput sensing and data movement, writing and maintaining C/C++ firmware for Zynq UltraScale+ MPSoC devices, or building Linux-based embedded systems using PetaLinux and Yocto, collaborating closely with digital, RF, signal processing, and systems engineers to deliver reliable, high-performance embedded solutions. The software and FPGA architectures you build will directly influence radar timing, data integrity, processing throughput, and system reliability on orbit.

As part of our quickly growing engineering team, you will play a critical role in building the world’s most advanced radar satellite constellation—one that will significantly improve humanity’s ability to rapidly and comprehensively understand our changing planet.
