Firmware Engineering Lead

Job description

**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 productsthat 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're building powered wearable robots for everyday life — devices that sit at the intersection of motor control, real-time embedded systems, and edge compute. We're 22 people, all senior, all contributing directly to product. This role leads a small firmware team while staying hands-on with the systems that matter most. You'll set the technical bar for how we build firmware at Skip, and develop the engineers around you while doing it. **What you'll own:** - Leading and growing a small firmware engineering team, including hiring, mentorship, and technical direction - End-to-end embedded C/C++ across our stack, including FreeRTOS, interrupt handling, JTAG/SWD debugging, and chip bring-up - Data communication between peripherals and microcontrollers (ESP32, STM32 and their successors), including Wi-Fi and BLE - Secure OTA pipelines and bootloader implementation - AWS IoT Core infrastructure: mTLS, MQTT, fleet provisioning, IoT Jobs OTA - Firmware for motor control across a range of actuators including BLDCs, custom PMSM and axial flux motors, cycloid gearboxes, and series elastic actuators (currently on c2000, evolving) - Technical direction for chip selection, actuator firmware requirements, and future system architecture - Adjacent product development including our Parkinson's device and future clinical and research platforms requiring edge compute - Wearing prototypes several hours a week for on-body testing and data collection - Bringing joy to the team, participating in embarrassing team events, and tolerating KZ's terrible music **What we're looking for:** - 8+ years in firmware development, with at least 2 leading or mentoring a team - Deep expertise in embedded C/C++ for high-performance, real-time applications including FreeRTOS - Proven experience with ESP32, STM32, or comparable chipsets - Strong background in AWS IoT Core, fleet management, and OTA systems - Solid Linux, Python, and command-line fluency - Experience with low-level hardware and OS internals at a kernel level - Rigorous debugging instincts across JTAG, SWD, oscilloscopes, and logic analyzers - The kind of technical credibility that makes people want to follow your lead, not just your title - Ability to work from our Bay Area office 3 days a week - Attention to detail, even in the middle of overly-long lists - Sense of humour. Tolerant of Aussie and Canadian spelling. **Bonus points:** - Experience with PMSM control on TI or STM chipsets - Background in robotics, powered consumer electronics, drones, or anything that moves - Familiarity with TFLite Micro or X-Cube-AI - Startup experience and comfort using AI coding tools to punch above your weight - Personal motivation to improve human movement This is a full time hybrid position working at the Skip office in the Dogpatch neighborhood of San Francisco.
