Motor Control Firmware Engineer

ABOUT US

Skip is on a mission to make life joyful through powered movement.

Movement is a powerful way to build physical, mental and social health. Yet it is elusive for 2 billion people due to age, injury, or disability. We are building products that will restore mobility for millions and enable a new frontier of joyful movement experiences. We want to build a future where a grandparent can easily outrun their grandkids and no one is left behind at the trailhead.

Skip is a 22-person early-stage start-up that spun out of Google X in 2023. With deep cross-disciplinary expertise and key partnerships (e.g. with Arc’teryx) we are uniquely positioned to launch the first commercially successful wearable robotic device , the MO/GO , develop a platform to launch future Movewear products and transform millions of lives in the coming years.

THE ROLE

We are seeking a highly motivated and adaptable individual who will explore the peaks and valleys of all problems that may come up while building a new generation of wearable robots for everyday life.

The mechatronics systems engineer would primarily be 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 but they need to be tested, improved and optimised with a whole-system approach.

We are a team of 22 phenomenal senior engineers and product leaders, where everyone contributes directly to product development. As such this will start as an individual contributor role, 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).

Some of the specific responsibilities include, but are not limited to

• Understand every element of our mechatronics system ; 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 productising 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 t o the team, participate in embarrassing team events, tolerate KZ’s terrible music

Basic Qualifications

• 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

Bonus Points

• 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
