Requirements

Bachelor of Science or advanced degree from an accredited university in Electrical/Electronic Engineering (or related field/curriculum having an Electrical concentration, such as Computer Engineering or Robotics Engineering). Significant commensurate experience may be considered.
Minimum 8+ years practical technical experience with focus and demonstrated expertise in custom-made (high-power) motor controls and other power conversion subsystems development, analysis, simulation, design, control, programming, layout, construction, troubleshooting, and testing.
Ability to obtain and maintain a United States Government Department of Defense Security Clearance (active clearances preferred, but not prerequisite).
Must be a US citizen.
Preferred qualifications:
(expected to possess practical expertise and perform many of these)
Expert understanding and application of three-phase brushless motors and controls models, electrical, magnetic, and mechanical, including dynamic flux estimation and transformations between stationary and rotating reference frames.
High-frequency space-vector pulse-width modulation (SVPWM) and other advanced techniques for efficient sinusoidal commutation, minimizing torque-ripple and excess harmonics.
Precise sensorless and sensored commutation/rotor angle sensing techniques.
Detailed analysis, modeling, and simulation of motors and motor controls in time domain, frequency domain, continuous and discrete.
Precise torque, speed, and position feedback control under varying loads.
Efficient implementation of motor controllers with embedded software/firmware in microcontrollers/DSP, using low-level assembly language and C language, including implementation of digital filters and phase-locked-loops (PLL).
Inverter topologies, state-of-the-art power device selection.
Power electronics design and component selection, including high-power IGBTs and MOSFETs, SiC, and associated drive, level-shifting, filtering, isolation, switching, sensing, common-mode effects, etc.
Application of similar principles to high-power active front end rectifiers for efficient, near-unity-power-factor, low-harmonics, AC-DC power converters, and complex interactions between front end and inverter(s).
Compact, optimal layout of motor control and drive circuitry (low- and high-power sections) on printed circuit boards for minimal noise, EMI/EMC, as well as heatsinking.
Good electrical drawing/drafting skills - accurately create and read detailed schematics, wiring diagrams, cable drawings, system cabling and block diagrams, etc.
Proficiency in proper use and application of various standard motor and electronic test equipment, e.g., dynamometers, VOM/multimeters, oscilloscopes, power analyzers, spectrum analyzers, "hipot" insulation testers, communications analyzers, etc.
Proficiency with advanced Computer Aided Design (CAD), Simulation, and Analysis software packages such as Altium Designer, SPICE, AutoCAD, SolidWorks, Mathcad, MATLAB, etc.
Proficiency with common office productivity software such as Microsoft Word, Excel, and PowerPoint, etc.
Good written and oral communications skills, including ability to effectively document, convey, and present engineering concepts and products to team members and customers.
Additional Desired Qualifications: (Stronger Candidates May Possess Some Of These):
Experience in the marine (surface or, preferably, underwater) industry and associated technologies, including ROVs, AUVs, and related robotic and electromechanical systems.
Experience with ground-fault (and other fault) monitoring and interruption for safety, especially in the marine, shipboard and underwater environment.
Applications with electronics (entire motor controller) immersed in oil, potentially under high-pressure.
Motor design and construction (housing, bearings, seals, stator, rotor, windings).
Experience with low-medium voltage, single- and 3-phase power systems (120, 240, 480, 3000+ VAC).
Experience applying machine safety systems and standards.
Good practical technician skills (assembly, wiring, soldering, cabling, etc.)
Ability and flexibility to travel on occasion, typically pre-planned for up to one to two weeks at a time; may be within the US, outside the US, or offshore, onboard a boat.

Responsibilities

Apply specific expertise to development of low to high power motor controls, drives, active front end rectifiers, other power conversion and supporting components.
As a system or subsystem lead, responsible for producing significant portions of individual project electrical and control system designs; may also be expected to lead, supervise, and mentor small teams of senior and junior electrical engineers in pursuit of associated project objectives.
Given incomplete, high-level requirements for a system or subsystem of moderate complexity, generate proper designs and work to complete tasking with latitude to make decisions under minimal supervision - individually and in a teamwork environment.
Exercise excellent technical judgement, creativity, and initiative with attention to detail consistently throughout your work product, with attention to the "system" perspective.
Prepare and participate in regular design reviews.
Work closely in concert with mechanical, software, and systems engineers, as well as other cooperative disciplines, to solve problems and constructively architect a working system.
Supervise/mentor junior engineers or technicians, when necessary.
Responsible and accountable for your results, working with considerable autonomy, but also knowing when to ask for assistance.
Desire to stretch and expand your talents, expertise, competency, and responsibilities.
