About The Position

Radiance Technologies is seeking a highly experienced hands-on technical lead to design, develop, prototype, and integrate missile subsystems. The role spans mechanical hardware, real-time embedded software, computer engineering architectures, Guidance, Navigation, and Control (GNC) algorithms, and Control Actuation Systems (CAS). The position serves as the primary hands-on technical architect and lead developer, translating program requirements into flight code, integrated actuator mechanisms, low-latency bus architectures, and HWIL testbeds. The Program Chief Engineer provides direction and retains final airworthiness and system sign-off authority. The role leads multidisciplinary development and trade studies; CAS engineering and integration; GNC algorithm development and flight-code generation; embedded software and computer architecture; and HWIL/PIL testing and root-cause analysis. It also supports proving-ground and flight-range activities, including pre-flight checkouts, telemetry decoding, and post-flight anomaly investigations.

Requirements

B.S. with 25+ years, M.S. with 15+ years, or Ph.D. with 10+ years of hands-on experience in Aerospace, Mechanical, Electrical, or Computer Engineering, or Computer Science.
Demonstrated experience as a lead technical developer or primary architect on at least one guided weapon, missile, or interceptor program from initial code/cad through flight test.
Practical expertise in missile mechanical structures, aerothermal heating considerations, structural dynamics, and electromechanical actuator/CAS integration.
Advanced capability in control theory, 6-DOF modeling, trajectory design, and guidance implementation.
Advanced proficiency in C/C++, Python, and MATLAB/Simulink, including automated flight-code generation via Embedded Coder.
Hands-on RTOS development experience with VxWorks, Linux PREEMPT_RT, or Green Hills INTEGRITY.
Embedded bus integration experience with MIL-STD-1553, ARINC 429, Ethernet/UDP, PCIe, CAN, SPI, or RS-422.
Must possess an active US DoW Secret security clearance.

Nice To Haves

Working knowledge of MIL-STD-882 system-safety practices or DO-178C software-development practices.
Experience interfacing directly with Chief Engineers, IPT Leads, and DoW customer technical teams during PDR/CDR design reviews.

Responsibilities

Lead hands-on development across mechanical structures, embedded software, onboard computer architectures, GNC algorithms, and CAS subsystems.
Formulate, model, and conduct multidisciplinary trade studies addressing mechanical mass and inertia, aerothermal loading, computational throughput, and control-loop latency.
Draft system and subsystem technical specifications, Interface Control Documents (ICDs), and qualification plans for Chief Engineer review and approval.
Lead engineering, dynamic modeling, and laboratory integration of high-speed electromechanical, hydraulic, or cold-gas-thruster Control Actuation Systems.
Analyze fin and nozzle dynamic response, thermal limits, gearbox compliance, and motor-drive performance under high-G and aerodynamic-load conditions.
Troubleshoot physical, electrical, and hydraulic failure modes, structural resonances, nonlinearities, and mechanical compliance issues.
Develop, simulate, and implement GNC algorithms, autopilot loops, Kalman filters, and trajectory optimization routines.
Translate 6-DOF flight-dynamics models into deterministic real-time C/C++ code for onboard flight processors.
Evaluate missile maneuvering performance, dynamic stability, and guidance accuracy across subsonic through hypersonic regimes.
Architect low-level embedded software frameworks for flight computers and FPGA, DSP, or SoC processing units and real-time communication buses.
Implement optimized C/C++ code and manage RTOS task prioritization, memory allocation, multicore synchronization, and interrupt service routines.
Conduct hardware/software co-design to ensure interface timing among flight computers, IMUs, seekers, and CAS drive electronics.
Design, build, and maintain HWIL and PIL simulation setups to test flight software with physical actuators and hardware under test.
Implement VV&A procedures for simulation tools and testbeds.
Deploy to remote proving grounds and flight-test ranges for pre-flight checkouts, real-time telemetry decoding, and post-flight anomaly root-cause analysis in support of the Chief Engineer.
