Senior Embedded Systems Engineer - Motor Control

Freefly Systems - Woodinville, WA (Onsite)

Freefly Systems, the company that redefined camera movement with the introduction of the Mōvi (a compact, lightweight, 3 axis camera stabilizer) is growing. We are on the lookout for a uniquely talented Senior Embedded Systems Engineer who loves Motor Control to get in on the fun.

As a member of the Freefly Team, you’ll join us on our mission to develop the next generation of innovative unmanned aerial vehicles, robotic systems, and consumer electronic devices in a fast paced, multidisciplinary, startup environment.

The ideal candidate is a jack of all trades with a diverse portfolio of built work spanning multiple industries and demonstrates a thorough understanding of complex electromechanical systems. Experience in multiple software packages, entrepreneurship/consulting, aerospace and/or consumer electronics are a plus. Most importantly, you must have a positive “can do” attitude, play well with others, embrace a challenge, and realize that every failure is a critical step toward creating innovative products.

• Should we consider a 6 phase/dual 3 phase motor from a redundancy / efficiency perspective? Is the ROI there?
• Real time stator temp estimation? Or just add thermistor to motor?
• For mission critical drone drives, how can we be certain a drive / motor / prop has failed?
• What is the right level of testing for a motor drive that is going on a drone?
• How can we automate this more in the future?
• How can we reduce flux angle error?
• How fast can we slew a motor / prop? What is the constraint in the system? Physics or our skill?
• What does the 10 year technology roadmap for drone motor control look like?
• How do we stay leaders?
• How do we make the world's most reliable motor drives?
• Once we make them reliable, how do we make them inexpensively!
• 3 vs 2 current shunts and phase or low side?
• GaN now or in the future? Reliability/Cost of GaN vs good silicon mosfets?
• How much isolation do we need for the gate drive and input?

• Lead product design engineering efforts for motor control, from concept through production
• Manage the product lifecycle and identify continuous improvement opportunities
• Architect PCB models from concept to mass manufacturable part
• Conduct materials, technology, and process research to develop products that achieve lofty performance requirements
• Perform simulation, testing, and analysis to ensure products that live up to Freefly name
• Multi task across a range of products in varying levels of completion while meeting schedules and hitting milestones
• Provide cross-functional support to internal and external teams
• Mentor and teach whenever possible

• Strong understanding of microcontroller architecture and programming
• ARM Cortex M3/M4/M7 experience
• Emphasis on real time high bandwidth control system theory, design, and implementation
• Serial digital communication knowledge (UART, I2C, CAN, SPI)
• Hands on experience with measurement and test equipment (oscilloscopes, DAQ’s, etc)
• Circuit design and PCB layout for mixed power/signal applications
• Application/GUI programming
• Experience with version control systems
• Solidworks or other parametric CAD software
• 5 years of industry experience (preferred)
• Excellent communication skills, verbally and written
• Experience working with multidisciplinary groups driving schedule and tasks
• Passion for learning, iterating, and first principles.
• Must posses great ‘feel’. We need to move fast and good hunches save time.

Salary Range: $100,000 - $150,000/yr
