About The Position

At Raytheon, the foundation of everything we do is rooted in our values and a higher calling – to help our nation and allies defend freedoms and deter aggression. We bring the strength of more than 100 years of experience and renowned engineering expertise to meet the needs of today’s mission and stay ahead of tomorrow’s threat. Our team solves tough, meaningful problems that create a safer, more secure world. The Effector Analog and Power Department is responsible for the development, from concept to integration, of Telemetry and Flight Termination products; power systems from all up round to the lowest level power regulation; servo electronics supporting all mechanical motion in our products and low noise mixed signal electronics that provides the analog to digital interface to our front-end sensors. Each of these products generally operate in lower power and voltage ranges less than 10kW and 1000V. What You Will Do Design, analyze, simulate, test, and document power conversion (and related analog) circuitry. This circuitry will dominantly involve non-isolated and isolated switch mode power converters and linear converters. Main emphasis is on board-mounted power end use applications. Architect at the power system level. See circuit card and stack development through its design phases, from requirements definition through initial integration testing. Includes leading large teams and defining schedules and system level tasking for designs. Guide ECAD drafters and junior engineers through layout and routing activities. Define layer stackup definitions. Act as an expert regarding creepage and clearance. Lead large teams to success with schedule, budget, and technical execution. Engage in personal technical growth and facilitate technical growth in peers and junior engineers. Drive the capture of opportunities needed to mature the organization on the technical front.

Requirements

Bachelor’s in Science, Technology, Engineering, or Mathematics (STEM) and 10 years of prior relevant experience
Design, analysis, test, and/or simulation experience with linear converters, and familiarity with all the following non-isolated converter topologies: buck, boost, buck-boost.
Professional design, analysis, and simulation experience with at least one of the following isolated converter topologies: flyback, half-bridge, full-bridge, forward, push-pull, resonant.
Experience with EMI Filter design, transformer or inductor design, analysis, test, and/or simulation considerations in power electronics circuits.
Analog electronics design, including the following: FETs/BJTs, op-amp, high/low/band pass filters, clock/data termination, and comparator circuits.
Active and transferable U.S. government issued security clearance is required prior to start date.
U.S. citizenship is required, as only U.S. citizens are eligible for a security clearance
Active and existing security clearance required on day 1

Nice To Haves

Advanced degree in Electrical Engineering
