Company: Rehabwheel Inc.
Location: San Francisco, CA (On-site, 655 Bryant St)
Commitment: Full-Time
Compensation: $25.00 / hour + Health Insurance
Company Overview
Rehabwheel Inc. develops an AI-powered, motor-assisted rehabilitation device that delivers personalized mobility recovery for wheelchair users and individuals with lower-limb impairments. By combining advanced hardware, embedded intelligence, and clinical insights, we improve outcomes and independence for patients.
Rehabwheel Inc. is an MCTX 19 Alumni cohort member and an EC Project Healthcare Portfolio Company, providing our team with deep healthcare expertise, strategic partnerships, and resources to accelerate product commercialization.
Role Overview
We are seeking a full-time, on-site Electrical/Firmware Engineer to join our team at our San Francisco workshop. In this role, you will bridge the gap between hardware and software, designing, developing, and testing the embedded systems and electrical circuits that drive our motor-assisted rehabilitation devices.
You will own the firmware execution on ARM-based architectures, troubleshoot complex hardware-software integration issues, and ensure institutional-grade reliability as we transition our platform from prototype to production.
Key Responsibilities
Firmware Development: Implement, optimize, and maintain real-time firmware for ARM-based architectures and microcontrollers.
Hardware & Circuit Design: Design and test electrical circuits, managing sensor integration, motor control loops, and power management.
System Integration & Debugging: Diagnose and resolve complex hardware/software integration bottlenecks using oscilloscopes, logic analyzers, and debuggers.
Cross-Functional Collaboration: Interface with the engineering team to ensure seamless mechanical, electrical, and software alignment.
Documentation & Compliance: Maintain rigorous design documentation, participate in design reviews, and support verification, validation, and medical-grade regulatory compliance activities.
Qualifications & Skills
Education: Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or a related technical discipline (or equivalent practical experience).
Embedded Software: Strong proficiency in C/C++ for real-time systems and bare-metal or RTOS embedded development.
Hardware Architecture: Deep understanding of ARM Architecture, low-level hardware interfaces, and communication protocols (UART, SPI, I2C, CAN).
Electrical Engineering: Solid foundation in circuit design, actuator/motor control, and robust power management.
Testing & Tools: Hands-on experience debugging embedded systems using standard laboratory equipment.
Preferred: Prior experience with medical devices, robotics, safety-critical systems, or ISO 13485 environments is highly beneficial.
Logistics: Ability to work effectively, hands-on, in an on-site laboratory environment in San Francisco.
