Freefly Systems
Senior Embedded Systems Engineer - Motor Control
Freefly Systems, Woodinville, Washington, United States, 98072
Freefly Systems - Woodinville, WA (Onsite)
About Freefly Systems
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. About the Role
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. We need your help to answer the following questions:
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? Responsibilities
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 Qualifications
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. Compensation
Salary Range: $100,000 - $150,000/yr If you’re interested in joining our team, drop us a line at careers@freeflysystems.com
and tell us about your exciting projects, what you’re learning… and a few war stories.
