Principal/Sr. Principal Power Supply Engineer

The Power Design Engineering role involves full life-cycle product development on architectures ranging from radio frequency electronic warfare (RFEW), infrared countermeasures (IRCM) and imaging systems, and real-time embedded control systems. The Power Design Engineer provides concept-to-production development, test, and integration of these technology areas:
• High efficiency, switch-mode power supply architectures for image processing, embedded processing, and Receiver/Exciter designs
• Subsystem/module circuit designs for custom and commercial-off-the-shelf (COTS) systems, involving COTS & MIL-STD interfaces.
• Regulatory compliance to DoD customer requirements, such as MIL-STD-704, 461, 464 & DO-160 and TEMPEST

The Principal/Sr. Principal Power Design Engineer will design and develop power conversion architectures using the latest technologies from Linear Technology, Texas Instruments, and other integrated circuit device manufacturers to support the following applications: gigabit serial interfaces, Radio Frequency (RF) and Electro-Optical (EO) DSP, controls, data links, and embedded processing platforms. Typical power outputs range from less than 1mW to greater than 10kW. Power Design Engineers work with system, sub-system, and hardware engineers to develop requirements, architect new circuit design topologies, and printed wiring board layouts. Designs are verified through spice simulation, laboratory verification, and formal qualification to electrical and mechanical environmental requirements, electromagnetic environmental effects (E3) requirements and EMI/EMC compliance requirements. Design support is continuous from requirements definition through integration and test; and maintenance of design documentation and configuration management is required throughout the product life cycle.
