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 Hardware Electrical Engineering Team is looking forexperienced engineers who have electronics knowledge to supportthe design and test of electronicproducts and systems.Our bread and butterareallthings "circuit cards",and we want you to help us blaze the path!

We’regrowing fast and we want you to grow with us!We’reexpanding our engineering organization dramatically to meet exciting customer demand, andwe’reactively looking for engineers who bring strong foundational skills and a passion for solving hard problems. Industry experience in defense? Not required —we’llinvest in you. If you meet the minimum qualifications, we want to talk.

What You Will Do

Raytheon’s Effector Analog & Power (EAP) Team is looking for mid-career engineers who have electronics knowledge to help design robust motor control 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 operates in lower power and voltage ranges less than 10kW and 1000V.

• Design, analyze, simulate, test, and document power conversion (and related analog) circuitry. This circuitry will dominantly involve 3 phase inverter design, sensor interfacing and controller circuits. Main emphasis is on board-mounted power end use applications.
  Hands on drafting & designing at a circuit card level.
• Help to see circuit card development through its design phases, from requirements definition through initial integration testing.
• Drive to meet schedule concerns. Define schedules for circuit level tasking.
• Guide ECAD drafters through layout and routing activities, with moderate support from senior engineers. Assist in layer stackup definition.
• Lead small teams & participate as a SME (Subject Matter Expert) on Controls Hardware Electronics.

Qualifications You Must Have

• Requires a degree in Science, Technology, Engineering, or Mathematics (STEM) and a minimum of 8 years of relevant experience; or Advanced degree in STEM and a minimum of 5 years of relevant experience.
• Design, analysis, test, and/or simulation experience with one or more of the following motor types is a plus: Brushed, BLDC or PMSM.
• Experience using tools such as MATLAB, MathCAD, Mathematica, or other similar tools.
• Experience with analog electronics design, including at least one of the following: FETs/BJTs, op-amp, high/low/band pass filters, clock/data termination, and comparator circuits.
• Experience working in a lab setting and using lab tools such as oscilloscopes, DMMs, frequency generators, power supplies and Data Acquisition Systems.
• Familiarity with wide bandgap devices (SiC, GaN) in power electronics designs.
• Design considerations for voltages > 400V and/or power > 10kW. Three-phase power systems, power factor control, and inverter/rectifier development.

Qualifications We Prefer

• An advanced degree in Electrical Engineering
• A self-starter, a quick learner, be able to function in a dynamic environment, and have good time management skills. Should have an appreciation for how successful teams are structured.
• Experience communicating and documenting technical topics at the small team level.
• Experience in any one of the following:
• Simulators such as SIMPLIS or SABER, or Mentor Graphics DxDesigner, and/or Hyperlynx.
• Multi-level three phase Inverter Design for HV applications
• Multi-isolated power systems design and component selection
• Hardware in the loop testing setup and design experience
