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. Every revolutionary invention begins with a simple electronic principle, proving small sparks can create massive change. Raytheon's Hardware Electrical Engineering Team is looking for experienced engineers who have electronics knowledge to support the design and test of electronic products and systems. Our bread and butter are all things “circuit cards”, and we want you to help us blaze the path! We're growing fast and we want you to grow with us! We're expanding our engineering organization dramatically to meet exciting customer demand, and we're actively looking for engineers who bring strong foundational skills and a passion for solving hard problems. Industry experience in defense? Not required — we'll invest in you. If you meet the minimum qualifications, we want to talk. Apply today and take the next step in your engineering career. 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 Effector 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.

Requirements

Requires a Bachelor’s in Science, Technology, Engineering, or Mathematics (STEM) and a minimum of 8 years of prior relevant experience OR an Advanced STEM degree and a minimum of 5 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/or 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/or creating electrical design specifications.
The ability to obtain and maintain a U.S. government issued security clearance is required.
U.S. citizenship is required, as only U.S. citizens are eligible for a security clearance.

Experience with using CAN-bus, UART, and/or RS-422.

Responsibilities

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.
