Electrical​/PCB Design Engineer; Clean Sheet​/Motion Control

Position Title

Electrical / PCB Design Engineer (Clean Sheet/Motion Control)

Protingent Staffing has an exciting contract opportunity for an Electrical / PCB Design Engineer with our client located in Seattle, WA. This role is focused on the clean sheet design and implementation of a motion control system for a next‑generation product.

• We are seeking a Mid to Senior level Electrical / PCB Design Engineer to lead the conception, design, and implementation of a new motion control system.
• This role requires expertise in system‑level architecture, board design, embedded systems, and sensor integration, ensuring a seamless transition from design through manufacturing.
• This is a clean sheet design and implementation project.
• The primary function is developing a motion control system for a next‑generation product.
• The system will primarily control Stepper motors, with experience in BLDC control being a strong bonus.
• Power requirements are relatively small (≤ 100 W).
• The location preference is local and on‑site due to the project's hardware nature.

• System Architecture & Design:
  Perform clean sheet design and implementation of the motion control system, focusing on power, control, and signal integrity.
• Motor Control:
  Design the control circuitry for the motion system, primarily targeting Stepper motors. Experience with BLDC control is a plus.
• Embedded Integration:
  Integrate the motion control PCB with the project's embedded systems, which utilize ST family MCUs and a central host running an NXP iMX
  6.
• Sensor Integration:
  Integrate various sensors typical for motion systems, including limit switches, distance sensors, force sensors, and temperature sensors.
• PCB Design:
  Execute all necessary schematic capture and PCB layout for the motion control board.
• Firmware Interface:
  While the base job does NOT require firmware development, multidiscipline candidates capable of interfacing with or modifying firmware are highly valued.

• Experience Level: Proven professional experience (Mid to Senior preferred). Minimum 1 year in motion control systems is required, with 5+ years of overall experience highly preferred for a senior candidate who can lead the effort from conception.
• Motion Control Expertise:
  Deep experience designing and implementing hardware for motor/motion control systems, specifically with Stepper motors.
• Embedded Systems Foundation:
  Strong working knowledge of embedded systems, specifically integrating with standard MCUs (such as ST series or similar ARM Cortex‑M4 derivatives).
• Sensor Integration:
  Demonstrated ability to integrate, interface, and design circuitry for various motion control sensors.
• System Leadership:
  Ability to drive a project from conception through design and into manufacturing (highly preferred for senior applicants).

• Experience in BLDC (Brushless DC) motor control.
• Experience with the ST Microcontroller family and/or NXP iMX6 host systems.
• Ability to read, modify, or write firmware for motion controllers (multidiscipline skill).

• Job Type: Contract (~4‑6 months estimated duration, with potential for extension).
• Location:
  
  Seattle, WA (In‑office 3+ days per week preferred. Remote is NOT possible due to the nature of the project and necessary hardware interaction.)
• Pay Rate Range: $95 – $135 / hour
