Radar Systems Software Engineer

About Us We are a stealth-mode Aerospace & Defense startup headquartered in Gardena, CA. Our founding team hails from SpaceX, Anduril, and Lockheed Martin, and we are backed by Joint Staff-level military leadership and top-tier Silicon Valley firms. Our mission is urgent: to develop and deploy life-saving missile defense systems that can be fielded globally, today. We are assembling a high-agency team committed to moving fast, solving hard problems, and defending what matters most. The Role We are seeking a Radar Systems Senior Software Engineer to lead the design, development, integration, and validation of radar and sensor software systems that detect, classify, track, and maintain target solutions for downstream fire control and engagement systems. This role sits upstream of the Fire Control Software function and is responsible for turning raw or partially processed sensor data into reliable, engagement-quality tracks and situational awareness products. You will work across radar software, sensor modeling, tracking logic, real-time systems, and software infrastructure to ensure the fire control system receives high-confidence target information in operationally relevant environments. This is a hybrid role for someone with equal strength in radar/sensor domain knowledge, software engineering rigor, and real-world program experience . We are looking for an engineer who has built and shipped radar, sensor fusion, tracking, or mission-system software in a defense or similarly demanding environment — someone who understands not just how to model these systems, but how to make them work on real hardware, under real timing constraints, with real operators and customers. You will join a highly effective software team with exceptional work ethic and strong execution velocity. Your role will be to bring depth in radar and sensing systems, strengthen our ability to build fieldable mission software, and help shape the architecture, validation approach, and engineering standards for a critical part of the kill chain. What You’ll Do Architect, build, and deploy radar and sensor-processing software that supports target discovery, tracking, classification, and status reporting for mission-critical defense applications. Develop and improve functionality such as radar mode logic, track initiation, track maintenance, correlation, filtering, state estimation, sensor resource management, and handoff of engagement-quality tracks to fire control systems. Design and implement software interfaces between radar/sensor subsystems, C2 nodes, mission software, simulation environments, and fire control components. Build high-performance, deterministic software in real-time or near-real-time environments where latency, fidelity, and robustness are critical. Develop radar and sensor models used for algorithm development, simulation, test, performance assessment, and system trade studies. Work across signal-processing-adjacent software, tracking pipelines, middleware, and distributed system infrastructure to support end-to-end sensing performance. Partner closely with fire control, systems engineering, hardware, integration/test, autonomy, and product teams to ensure the sensing stack supports mission outcomes. Contribute to verification and validation through software-in-the-loop, hardware-in-the-loop, lab integration, range events, and field exercises. Support performance analysis of radar and sensor systems in clutter, degraded conditions, electronic attack environments, or other operationally realistic scenarios. Help define requirements, interface control documents, test strategies, and review artifacts for internal development and external customer engagement. Mentor teammates and raise the team’s capability in radar systems, sensor modeling, tracking software, and defense-grade engineering rigor.
