Senior Electrical Engineer

About the role

Radiance Technologies, a rapidly growing employee-owned company, is seeking a Senior Electrical Engineer to play a key role in the design, development, integration, and qualification of missile electronics, power architectures, and electrical interconnect systems. In this position, you will be responsible for the hands-on engineering of onboard avionics, power distribution, sensor/seeker interfaces, Control Actuation System (CAS) drive electronics, flight telemetry systems, and inertial sensor integration.

You will own hardware across the full lifecycle-from concept design and schematic capture through circuit simulation, physical PCB layout, prototype bringing-up, environmental testing, and flight test support.

Key Responsibilities

• Electrical Hardware & Avionics Design
• Design, analyze, and test high-reliability, ruggedized printed circuit board assemblies (PCBAs) for onboard flight processing, signal conditioning, power conversion, and motor control.
• Develop power supply electronics and power conditioning circuits tailored for high-strain missile environments (utilizing thermal batteries, linear/switching regulators, and protection networks).
• Design motor drive electronics and high-current power stages for electromechanical actuators (CAS) and thrust vector control (TVC) systems.
• Subsystem Integration & Interconnects
• Integrate Guidance, Navigation, and Control (GNC) sensors (Inertial Measurement Units, GPS, altimeters) and seeker payloads with flight computer interfaces.
• Design MIL-spec cable harnesses and interconnect systems engineered to withstand extreme acceleration, vibration, shock, and thermal loads.
• Develop and maintain Electrical Interface Control Documents (ICDs), schematic diagrams, and system wiring topologies.
• Signal Integrity, EMI/EMC, & Qualification
• Implement Electromagnetic Interference (EMI), Electromagnetic Compatibility (EMC), and shielding techniques per military standards.
• Perform circuit simulations, signal integrity (SI) analysis, and thermal-electrical derating evaluations for critical avionics components.
• Support and execute environmental qualification testing of electronic assemblies under thermal vacuum (TVAC), vibration, pyroshock, and thermal shock conditions.
• Lab Testing, HWIL, & Field Support
• Design and build Electrical Ground Support Equipment (EGSE), test fixtures, and breakout boxes for laboratory integration and Hardware-in-the-Loop (HWIL) testing.
• Perform detailed troubleshooting, failure analysis, and root-cause investigations on hardware anomalies during bench testing, HWIL runs, or field operations.
• Support remote test range campaigns for pre-flight checkouts and post-flight telemetry/data analysis.

Required Qualifications & Technical Stack

• Education: B.S. in Electrical Engineering or Computer Engineering with 5+ years of experience, or M.S. with 3+ years of experience in aerospace, defense, or high-reliability electronics design.

IMU & Inertial Sensor Experience

• Direct hands-on experience integrating tactical or strategic-grade IMUs (RLG, FOG, or high-performance MEMS IMUs such as Honeywell, Northrop Grumman, or Analog Devices units).
• In-depth understanding of IMU electrical interfaces, clocking/synchronization protocols, dynamic range constraints, and noise-sensitivity characteristics.
• Circuit Design & Tools:
• Proven track record in schematic capture and PCB layout using industry-standard EDA tools (Altium Designer, Cadence Allegro, or Mentor Graphics/Siemens EDA).
• Hands-on experience with mixed-signal, analog, high-speed digital, and power conversion (DC-DC) design.
• Bus Protocols & Interfaces:
• Experience implementing standard defense and industrial communication buses (MIL-STD-1553, ARINC 429, Ethernet/UDP, CAN bus, RS-422/485, SPI, I2C).
• Military Standards & Test:
• Working knowledge of key military standards (MIL-STD-461 for EMI/EMC, MIL-STD-810 for environmental testing, and MIL-STD-704 for aircraft/missile power).
• Security Clearance: Must hold an active US DoD Secret security clearance with eligibility for Top Secret / SCI.

Desired Qualifications

• Experience designing drive electronics for brushless DC (BLDC) motors or actuators.
• Background in ordnance safety design or electronic fuzing (ESAD/ESAF) circuits per MIL-STD-1901A.
• Familiarity with RF interfaces, antennas, or telemetry transmitters.
• Basic FPGA development (VHDL/Verilog) or micro-controller firmware integration experience.
