About The Position

At Array Labs, we are building the worldâs most advanced radar imaging satellites to produce an accurate, continuously updated 3D map of the Earth â providing governments and commercial organizations with critical insights into the physical world. We design and build our entire radar system in-house, from antenna panels and RF front-ends to digital electronics, calibration systems, and data processing. This vertical integration gives us control over the electrical, thermal, and mechanical constraints that set the limits on radar performance and system reliability. As an Embedded Software Engineer, you will develop the embedded software that enables Arrayâs radar sensors, communication links, and flight systems to operate reliably in orbit. Your work will include board bring-up of Linux-based platforms, high-performance data movement between sensors and compute elements, integration with FPGA and RF subsystems, and the development of safety-critical control and FDIR algorithms. You will collaborate closely with signal processing, hardware, and GNC engineers to prototype, evaluate, and deploy software architectures that meet demanding latency, throughput, and reliability requirements. The software you build will directly influence radar performance, system robustness, and mission resilience on orbit. As part of our quickly growing engineering team, you will play a critical role in building the worldâs most advanced radar satellite constellationâone that will significantly improve humanityâs ability to rapidly and comprehensively understand our changing planet.
