Mechatronics / Power Train Lead

Skip • San Francisco, CA

5d • Hybrid

About The Position

Skip is seeking a highly motivated and adaptable individual to explore the peaks and valleys of all problems that may come up while building a new generation of wearable robots for everyday life. This engineer will be primarily responsible for the design, development, testing, and validation of our powertrain, including motor control for novel actuators and complex battery management. The team has just finished an “EVT” build, so we have functional prototypes that need to be tested, improved, and optimized with a whole-system approach. This role starts as an individual contributor with leadership for critical systems and directing work for people contributing to the system (e.g., working closely with our test engineer and gearbox designer).

Requirements

• 5+ years’ experience working in robotics or mechatronics
• Extensive experience controlling PMSM, including Ti and STM chipsets
• Experience with design for systems at scale, with a focus on testing and validation
• Demonstrable expertise in C/C++ for high performance applications
• Expertise with Linux, command-line tools, Python scripting
• Strong experience developing real-time firmware for multi-sensor systems
• Knowledge of low level hardware and OS internals at a kernel level
• Attention to detail, even in the middle of overly-long lists
• Experience with troubleshooting tools (JTAG, SWD, oscilloscopes, logic analyzers)
• Ability to work at the Skip Bay Area office >3 days/week
• Sense of humour, tolerant of Aussie & Canadian spelling

Nice To Haves

• Experience with powered consumer electronics (e.g. drones, robot vacuums)
• Experience in start-up environments and using AI coding tools to leverage your skills for broader impact
• Personal motivation to improve human movement
• Good taste in background music :)

Responsibilities

• Understand every element of our power train; being the go-to person for troubleshooting
• Guide design and development decisions for future iterations of the product, and future systems; including battery and motor specifications, motor control chip selection and firmware requirements
• Own the testing protocol to validate performance of the mechatronics at volumes and standards relevant to consumer products (and work with our Test Engineer to execute)
• Help us precisely control a range of actuators including off-the-shelf BLDCs, custom PMSM and axial flux motors, cycloid gearboxes, and series elastic actuators, including writing firmware for our motor control chip (currently c2000; but likely to change over time)
• Characterize and model our actuators for open-loop and closed-loop torque control.
• Create thermal models and evaluate the thermal limits of the actuator.
• Own the process of productizing our novel actuation systems as standalone products and components of a broader platform
• Wear prototypes several hours a week to participate in data collection, on-body testing and provide feedback
• Bring joy to the team, participate in embarrassing team events, tolerate KZ’s terrible music
