Quartermaster is building the world's most comprehensive maritime intelligence platform. We are seeking a Senior Software Engineer to help build the software backbone of our RF sensing platform—the edge applications, distributed data pipelines, and cloud services that turn raw spectrum captured on vessels into real-time maritime intelligence. You will work with RF, FPGA, and hardware engineers to move timestamped IQ data and detections from the mast to the cloud, and to process that data at scale as our sensor network grows into thousands of units. Location: Arlington, Virginia, United States. This role sits at the intersection of systems software, cloud data processing, and RF. You do not need to be an RF engineer, but you should have worked with or alongside RF or SDR software and understand sample rates, timing, throughput, and hardware that lives in harsh, remote environments. You will own components end-to-end, work directly with customers to shape requirements, and collaborate closely with a small, senior team where every engineer's work is visible in the field.
