About Us:

At Raytheon Missiles & Defense, you have the opportunity to try new things and make a bigger difference across a broader end-to-end solution, a richer technology and product set, an expanded range of disciplines, a growing global footprint and a more diverse team of colleagues and customers.

Job Summary:

The Low Voltage Power Products (LVPP) Department supports key Raytheon Missiles and Defense (RMD) products, by providing mission-critical designs relating to power conversion, motor controls, flight termination systems, telemetry, and other analog domains.

Do you have conceptual familiarity and/or experience with any one of the following isolated converter topologies: flyback, half-bridge, full-bridge, forward, push-pull, resonant?

We are looking for mid-level engineers who have power electronics knowledge to help design robust power systems for important national defense products. The successful candidate must be a self-starter, a quick learner, be able to function in a dynamic environment, and have good time management skills.

Responsibilities to Anticipate:
  • 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 circuit card level.
  • Architect at the circuit card level.
  • See circuit card development through its design phases, from requirements definition through initial integration testing.
  • Drive to meet schedule concerns. Define schedules for circuit and circuit card level tasking.
  • Guide ECAD drafters through layout and routing activities, with minimal support from senior engineers. Define layer stackup definitions. Be aware of creepage and clearance concerns.
  • Lead small teams to success with schedule, budget, and technical execution.
  • Engage in personal technical growth, and encourage technical growth in peers and junior engineers.
  • Clearly present work product of your team to functional and program leadership. Participate in risk management discussions. Begin to guide junior engineers on technical presentation skills.
Qualifications You Must Have:
  • Bachelors in Science, Technology, Engineering, or Mathematics (STEM)
  • 5+ years of related experience
  • Design, analysis, test, and simulation experience with linear converters, and one or more of the following non-isolated converter topologies: buck, boost, buck-boost.
  • Experience using tools such as MATLAB, MathCAD, Mathematica, or other similar tools. Must have experience developing templates with these tools.
  • Analog electronics design, including at least four of the following: FET/BJT logic level, op-amp, high/low/band pass filters, clock/data termination, and comparator circuits.
  • The ability to obtain and maintain a U.S. security clearance. U.S. citizenship is required as only U.S. citizens are eligible for a security clearance.
Qualifications We Value:
  • Advanced degree in Electrical Engineering
  • Conceptual familiarity and/or experience with any one of the following isolated converter topologies: flyback, half-bridge, full-bridge, forward, push-pull, resonant. Conceptual familiarity and experience should include stability.
  • Understanding of switching converter control techniques and modes such as voltage mode, peak and average current modes, their advantages and disadvantages.
  • Experience conducting trade studies relating to power electronics architecture at the circuit card level.
  • Experience guiding drafters through the ECAD process, including the layout and routing concerns specific to non-isolated converters. Should have a conceptual understanding of the layout and routing concerns specific to isolated converters.
  • Experience communicating and documenting technical topics at the small and large team level, and experience presenting to lower levels of management.
  • Conceptual familiarity with EMI Filter design and analysis considerations in power electronics circuits.
  • Experience leading small teams (formally or informally).
  • Experience designing at the circuit card level to meet concerns of adjacent disciplines, such as thermal, structural, mechanical, reliability, and quality.
  • Utilizing and creating electrical design specifications.
  • Exposure to professional transformer and inductor design, analysis, test, and simulation considerations in power electronics circuits. Should have a conceptual understanding of core material properties and their selection.
  • Introductory professional experience with:
  • Digital power electronics design, analysis, simulation, and test. Includes familiarity with embedded systems architecture and firmware development for digitally controlled power supplies.
  • Wide bandgap devices (SiC, GaN) in power electronics designs
  • Circuit simulator SIMPLIS, and/or system simulator SABER.
  • Mentor Graphics DxDesigner, and/or Hyperlynx.
  • Acting as a liaison between program and functional management in a cross-matrixed organization.
  • Military specifications.
  • Design considerations for voltages > 400V and/or power > 10kW.
  • Three-phase power systems, power factor control, and inverter/rectifier development.
  • Motor control development.
  • Program management tools such as Earned Value.
  • Proposal development.
What We Offer:

Whether youre just starting out on your career journey or are an experienced professional, we offer a robust total rewards package that goes above and beyond with compensation; healthcare, wellness, retirement and work/life benefits; career development and recognition programs. Some of the superior benefits we offer include parental (including paternal) leave, flexible work schedules, achievement awards, educational assistance and child/adult backup care.

Additional Details:
