Date Posted: 2026-04-16 Country: United States of America Location: US-AZ-TUCSON-M02 ~ 1151 E Hermans Rd ~ BLDG M02 Position Role Type: Onsite U.S. Citizen, U.S. Person, or Immigration Status Requirements: 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 Security Clearance Type: DoD Clearance: Secret Security Clearance Status: Ability to obtain INTERIM U.S. government issued security clearance is required prior to start date

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. Raytheon's Effector Analog & Power (EAP) Team is looking for junior to mid-level engineers who have power electronics knowledge to help design robust power systems. The EAP 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.

Qualifications – You Must Have

• Bachelor’s in Science, Technology, Engineering, or Mathematics (STEM) and 8 years of prior relevant experience
• Design, analysis, test, and/or simulation experience with linear converters and any of the following non-isolated converter topologies: buck, boost, buck-boost.
• Design, analysis, and simulation experience with at least one of the following isolated converter topologies: flyback, halfbridge, full-bridge, forward, push-pull, resonant.
• Experience using tools such as MATLAB, MathCAD, Mathematica, or other similar tools.
• Experience with EMI Filter design, analysis, test, and/or simulation considerations in power electronics circuits.
• Experience with transformer or inductor design, analysis, test, and/or simulation considerations in power electronics circuits.
• Experience utilizing, and creating, electrical design specifications.

Qualifications – We Prefer

• Advanced degree in Electrical Engineering
• Understanding of switching converter control techniques and modes such as voltage mode, peak and average current modes, their advantages and disadvantages.
• Conceptual familiarity and experience must include stability.
• Experience leading small teams (formally or informally), and experience working with other team leads toward a larger goal.
• Should have exposure to managing customer relationships.
• Experience communicating and documenting technical topics at the small and large team level, and experience presenting to upper levels of management.
• Experience conducting trade studies relating to power electronics architecture at the circuit card stack level.
• Experience guiding drafters through the ECAD process, including the layout and routing concerns specific to non-isolated and isolated power electronics.
• Experience utilizing and creating electrical design specifications.
• Should have exposure to requirements definition early in the design cycle.
• Experience designing at the circuit card stack level to meet concerns of adjacent disciplines, such as thermal, structural, mechanical reliability, and quality.
• Experience with Texas Instruments C-2000 family of microcontrollers, Microchip PIC controllers, VHDL, or real time operating systems.
• Experience with using CAN-bus, UART, and/or RS-422.
