Senior/Principal Software Engineer

Radiance Technologies, a rapidly growing employee-owned company, is seeking a seasoned Senior/Principal Software Engineer to lead the design, development, integration, and verification of software for advanced missile and guided-projectile systems. In this role, you will be the bridge between flight dynamics theory and real-time embedded execution, owning the software architecture for Guidance, Navigation, and Control (GNC), managing complex Hardware-in-the-Loop (HWIL) simulation labs, and supporting end-to-end flight test campaigns. Key

• GNC & Embedded Software Development Design, implement, integrate, and verify mission-critical missile software, focusing heavily on GNC algorithms, autopilot loops, and flight control laws. Translate complex mathematical flight dynamics models into high-performance, deterministic, real-time code. Utilize Model-Based Design (MBD) frameworks (e.g., MATLAB/Simulink auto-coding) to transition control algorithms seamlessly into target hardware. 2. Hardware-in-the-Loop (HWIL) & Simulation Management Architect, maintain, and expand HWIL test environments, integrating flight computers, inertial measurement units (IMUs), actuation systems, and sensor suites. Plan and execute rigorous HWIL test campaigns to validate software performance against simulated aerodynamic threats, target profiles, and environmental disturbances. Troubleshoot complex, multi-domain system failures spanning software logic, digital/analog signal interfaces, a
