Job Summary:

The Control Systems section within the Sensor Power Department (SPD) has an exciting employment opportunity for a Senior Engineer with motion control experience.   This role requires an understanding and working knowledge of classic control theory and vector control of electric motors; familiarity with IGBT- or MOSFET-based power electronics inverters used as motor drives (including rectifier front end); and familiarity with induction and permanent magnet electric machines.

The Control Systems section is a team of engineers responsible for supporting the design, development and validation of power and actuation (servo) subsystems for various radar systems and other defense applications.

As a Senior Engineer – Motion Control you will be responsible for supporting and driving the execution of product development projects. You will be working as or with a Team/Technical Lead and under the guidance of an Integrated Product Team (IPT) Lead.

SPD is responsible for design engineering including the following areas:

  • Power System Design - Power System Noise, System Simulation and Modeling, Solid State Transmitters, Tube Transmitters, High Voltage Design, Power Sources, Generators
  • Power Conversion - AC/DC, DC/DC and DC/AC, Linear and Switching Supplies, Power Factor Correction (PFC), Zero Voltage Switching (ZVS), Resonant Circuits, Synchronization, Noise Controls
  • Power Distribution - Ground, Air, Shipboard, and Space, Power Generation, Line Voltage, High Current, Low Voltage, Micro-Power, DC, AC, Multi-Phase Power Control, Fault Reporting, Isolation, Protection Circuits, Redundant Systems
  • Power Sub-System Design - Filters, Harmonic Control, EMI, Circuit Simulation, Magnetics, Protective Relay Systems, Short Circuit and Stress Analyses
  • Control Systems – Servo Control Systems, Motor/Power/Process Control, Digital Feedback Systems, Command Generation, Inertial Stabilization, Navigation Algorithms

This position is an onsite role

Responsibilities to Anticipate:

  • Designing and evaluating servo control hardware and/or software solutions to meet system operational and performance requirements
  • Developing models and controllers for actuation systems (including mechanical subsystems)
  • Establishing performance, stability and control metrics along with the algorithms necessary to achieve them
  • Supporting system integration efforts
  • Ownership and execution of scope, cost and schedule within programs and projects with minimum supervision
  • Defining tasks and providing direction to junior-level engineering and support staff
  • Work in a multidisciplinary team environment focused on execution and engineering excellence, using established business, and engineering tools and processes
  • Travel to Marlborough, MA; Andover, MA; Woburn, MA; and/or Pelham, NH may be required depending on the assignment.

Basic Qualifications:

  • Bachelor’s or Master’s degree in Electrical Engineering or related Science, Technology, Engineering, or Mathematics (STEM) major.
  • 5+ years of experience in power system design, power conversion, power distribution, power sub-system design and/or control systems
  • Experience in modeling and simulation using PSPICE, MATLAB/Simulink, or similar computer-based tools.
  • Experience with hardware and software implementation of closed-loop position/speed control actuation systems
  • Experience with 1-100 kW systems (bus voltages in the range of 270-1000 VDC)
  • Experience in control system design using Matlab/Simulink or equivalent
  • The ability to obtain and maintain a https://U.S. government issued security clearance is required. https://U.S. citizenship is required, as only https://U.S. citizens are eligible for a security clearance.

Preferred Qualifications:

  • Understanding and working knowledge of classic control theory and vector control of electric motors
