  • Drive to meet schedule concerns. Define schedules for circuit, circuit card, stack, and control system level tasking.
  • Guide ECAD drafters and junior engineers through layout and routing activities. Define layer stackup definitions. Act as an expert regarding creepage and clearance concerns.
  • 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 are needed to mature the organization on the technical front.
  • Clearly present work product of your team to functional, program, and corporate leadership. Manage related risk discussions. Guide junior engineers on technical presentation skills.

Qualifications You Must Have:
  • A Bachelors (or higher) in Electrical Engineering is preferred. Related Science, Technology, Engineering, or Mathematics (STEM) Bachelors (or higher) may also be considered.
  • Ten years of related experience in 6 or more of the following:
    • Design, analysis, test, and simulation experience with analog or digital controls, and driving one or more of the following motor types: Brushed, BLDC or PMSM.
    • Design, analysis, and simulation experience with servo control systems, drive electronics, feedback signals and sensing. Conceptual familiarity and experience must include control loops and stability of linear control systems.
    • Experience with professional sensor (magnetic encoder, resolver, Hall Effect) use design, analysis, test, and simulation considerations in control electronics circuits.
    • Experience with sensors and their selection. The ability to roadmap sensor technologies as they pertain to the direction of future business.
    • Experience with professional EMI Filter design, analysis, test, and simulation considerations in control electronics circuits. The ability to roadmap EMI Filter design in control electronics circuits as it pertains to the direction of future business.
    • Experience with analog electronics design, including all of the following: FET/BJT logic level, op-amp, high/low/band pass filters, clock/data termination, and comparator circuits, along with an understanding of how these circuits are utilized in control electronics. The ability to roadmap analog electronics design in control electronics circuits as it pertains to the direction of future business.
    • Experience conducting trade studies relating to control electronics architecture at the control system level.
    • Experience guiding drafters through the ECAD process, including the layout and routing concerns specific to control electronics. The ability to roadmap PCB design relating to control electronics circuits as it pertains to the direction of future business.
    • Experience with designing at the control system level to meet concerns of adjacent disciplines, such as thermal, structural, mechanical, reliability, and quality.
    • Experience utilizing and creating electrical design specifications.
    • Experience with requirements definition early in the design cycle.
    • Experience leading larger teams, and experience working with other team leads toward a larger goal. Direct experience managing customer relationships.
    • Experience communicating and documenting technical topics at the small and large team level, and experience presenting to upper levels of management and customers.
  • The ability to obtain and maintain a US security clearance. U.S. citizenship is required as only U.S. citizens are eligible for a security clearance

Qualifications We Value:
  • Be a self-starter, a quick learner, be able to function in a dynamic environment, and have good time management skills.
  • We value experience and/or conceptual familiarity with any of the items listed below:
  • Digital control electronics design, analysis, simulation, and test. Includes familiarity with embedded systems architecture and firmware development for digital control systems.
  • Wide bandgap devices (SiC, GaN) in control electronics designs.
  • Circuit/system simulator SaberRD, and MATLAB Simulink. Knowledge of dSPACE is not required but desirable.
  • 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 > 100V.
  • 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:

This position requires the eligibility to obtain a security clearance. Non-US citizens may not be eligible to obtain a security clearance. The Defense Industrial Security Clearance Office (DISCO), an agency of the Department of Defense, handles and adjudicates the security clearance process. More information about Security Clearances can be found on the US Department of State government website here:
