- power supply
This position is for a professional in the Hardware Electrical Power Engineering sub-family, who works independently and with a team. In this role as an electrical power engineer, you have the opportunity to design, analyze, simulate, and test system and module power architectures.
The electrical power engineer focuses on module development, system integration and test, new product introduction, and operations support. You are a part of a dedicated hardware electrical engineering team that collaborates within hardware and across the organization. The hardware electrical engineer bridges between program/product management, system/architecture engineering, mechanical/CAD, software, manufacturing, and customers. The electrical power engineer will be responsible for reporting and presenting to management and externally to customers. The electrical power engineer also interacts with third party partners that deliver power products to Mercury.
The hardware electrical engineer develops power distribution systems for high-end processing subsystems with up to 20 or more complex circuit assemblies. The input high power system architecture includes AC and DC, 24V to 270V. The power supply outputs include DC 28V, 12V, 5V, and 3.3V. The power sub-system may be comprised of a single supply or scaled in a parallel for higher power and redundancy. System power architecture typically includes cabling, Line-Voltage-Filter, backplane, and power modules. Other support circuitry in the system and on the power supplies includes interfaces such as PMBus, I2C, Clocking, JTAG, UART/RS232, and other IOs.
To succeed in this role, you should have the following skills and experience
• B.S. in Electrical or Computer Engineering, or equivalent professional experience; 10+ years
• Skilled at design, analysis, simulation, debug, and test
• Experience with AC (60Hz/400Hz) and DC Voltages (24V to 270V)
• Experience with power factor correction
• Experience with Line-Voltage-Filters (LVF)
• Experience with AC/DC and DC/DC high powered converters
• Experience with power load testing and scope measurements
• Skilled with Simulation tools such as LTSPICE, HSPICE and Ansoft.
• Experience in Military Power Standards (MIL STD 461F, 1275D, 704F, DO160G/1399 and others)
• Experience with VITA-62 (Module Power Supply), VITA-48 (Mechanical)
• Experience with EMI/EMC Radiated and Conducted Emissions Qualification (CE101, CE102, RE101, RE102, and others)
• Experience with EMI/EMC Susceptibility and Safety
• Skilled with component and system level troubleshooting for power, digital, and analog circuits
• Skilled with standard electronics test and measurement tools (scopes, multi-meters)
• Familiar with schematic capture (Mentor DxDesigner, Cadence Concept, or equiv.)
• Skilled at PCB layout analysis and review (Cadence Allegro or equivalent)
• Good communication skills, both written and oral
• Good organizational, analytical, and creative problem-solving capabilities
• Must be self-motivated in order to achieve assigned objectives with minimal supervision
