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.

Basic Qualifications Bachelor’s degree in Computer Science, Electrical Engineering, Aerospace Engineering, Physics, Applied Mathematics, or another relevant technical field.

8+ years of experience developing software for radar systems, sensor systems, tracking systems, mission systems, autonomy, or other high-performance real-world platforms.

Strong software engineering foundation, including experience designing, implementing, testing, and debugging production-quality systems. Strong proficiency in C++ and Python .

Experience developing on Linux in performance-sensitive environments.

Experience building software for one or more of the following: radar systems, EO/IR systems, RF sensing, tracking systems, sensor fusion systems, air and missile defense systems, or related defense platforms.

Familiarity with estimation, filtering, tracking, classification, or multi-sensor correlation concepts. Experience working in cross-functional environments involving hardware, embedded systems, integration/test, and systems engineering.

Ability to reason clearly about concurrency, latency, failure modes, and real-world deployment constraints.

Strong written and verbal communication skills, including the ability to work directly with technical leadership, operators, and government customers. U.S. citizenship and ability to obtain and maintain a U.S. security clearance.

Preferred Qualifications Direct experience with radar systems engineering , sensor modeling , tracking algorithms , targeting pipelines , or battle-management / mission-system software .

Experience developing or integrating software for active electronically scanned array (AESA) radar, surveillance radar, fire control radar, counter-UAS radar, or missile-defense radar systems.

Experience with state estimation and tracking methods such as Kalman filtering, probabilistic tracking, multi-hypothesis tracking, sensor fusion, or related techniques.

Experience building modeling and simulation environments used to validate radar behavior, track quality, and mission performance. Experience with HIL/SIL/HWIL environments, lab integration, and range or field-test support.

Familiarity with RF system concepts such as waveforms, detection theory, clutter, false alarms, jamming, or electronic warfare impacts at the software/system level.

Experience with distributed systems, real-time messaging, and low-latency communication frameworks. Experience supporting DoD, IC, or allied military programs in classified or restricted environments.

Familiarity with modern DevSecOps workflows in defense environments, including CI/CD, automated test, release discipline, and reproducible infrastructure. Experience with Java, Rust, CUDA, or GPU-accelerated processing is a plus.

Active Secret or Top Secret clearance.

What Great Looks Like The strongest candidates have worked on radar or sensing systems that mattered operationally — not just in theory, not just in simulation, and not only at the algorithm-research layer.

They have built software that connected sensor behavior to mission outcomes, and they understand what it takes to make target tracks trustworthy enough for downstream operators and fire control systems to act on.

They are equally comfortable discussing radar performance, sensor models, track quality, systems architecture, and production software design.

They know how to move between modeling and field reality, between code and hardware, and between technical depth and customer credibility.

Most importantly, they understand that in this role, radar is not an isolated subsystem — it is the front end of the engagement chain.

Their work will directly determine whether the system can find, follow, and hand off the right targets for successful engagement.

Why Join Us You will work on high-consequence national security problems with a small, elite, execution-focused team.

You will have unusual ownership, real technical influence, and the opportunity to help define the sensing architecture of a mission-critical defense system from the ground up. Itar Requirements To conform to U.S.
