Lead development of embedded software for advanced powered exoskeleton systems including real-time motor control, gait detection, and sensor fusion.

Hardware on real operators in real field conditions within weeks of concept, not years
Firmware updates ship over the air every one to two weeks
Small team, one owner per category, nobody owning a slice of someone else's problem

Own the full control stack: FOC and current loop, torque control, joint control, the gait and assist algorithm, and user intent detection above it
Set the architecture, interfaces, and standards the rest of the engineering team writes against
Decide how the device behaves when something goes wrong: sensor faults, low battery, unexpected loads
Own the update path: over-the-air firmware, rollback, and the telemetry link to the app
Build the data collection that turns field use into design decisions
Hire and lead the firmware engineers who build under you
Run field tests and turn what you see there into changes to the system
To apply for this role, provide us with the best evidence of your ability to execute. We would like to see what you have designed, built, and tested, so please include links, video, and photographs. A resume is welcome but not required. None of this has to be a perfect match. We care more about raw ability than a checklist, so if that's you, reach out.

Bachelor's degree in electrical engineering, computer engineering, computer science, or another engineering discipline
8+ years of embedded firmware experience, including ownership of a complete stack on hardware that shipped and was used by real people
Proficiency in embedded C or C++ and real-time systems
BLDC motor control at the loop level: FOC, current and torque control, and position, velocity, or impedance control
Full time and in person in Palo Alto
Travel to field tests, including overseas
Must be willing to work extended hours and/or weekends as needed

You can name the MCU, the RTOS or bare metal design, the loop rates, and why you chose each
Encoder processing, IMU and sensor fusion, high frequency control loops, and CAN
Running learned models on a microcontroller: quantization, inference budgets, and keeping a network fed inside a hard real-time loop
State machine or actor-based embedded architectures, built-in self test, and fault handling on hardware people depend on
You understand how the physical product gets built, not only how it is programmed. You have specified parts, worked with suppliers, and know what manufacturing does to an electronics design
You have set architecture other engineers wrote against, and you still write code yourself
You have taken over someone else's system, including undocumented or inherited code, and made it yours
Safety-critical or medical device firmware
Debugging hardware you cannot physically touch, from logs alone
Things you build outside work: motor controllers, robots, your own RTOS

's mission is to remove civilization-level physical constraints limiting the human body. We believe a future where humans keep pushing into the unknown is far better than one where we send machines in our place. That starts on the battlefield, doubling what a soldier can carry and how far they can carry it. Read more about our mission here .
As a Principal Engineer of Embedded Systems, you will be responsible for advancing technical boundaries of firmware and control for the world's most advanced powered exoskeleton systems, worn by soldiers in active combat. You will work with a talented team of accomplished engineers to develop the embedded software stack, including real-time motor control, gait detection, human intent inference, and sensor fusion. You should thrive in a fast-paced, dynamic environment where you adapt quickly, love to solve hard problems, and are confident enough to make the call and secure enough to take real pushback on it.
This is a foundational role. Your architecture and decisions will define what this company builds for years to come.
