We’re looking for a Controls & Firmware Engineer to make our exoskeleton walk.
You’ll own everything that runs on the device: the low-level firmware, the controls algorithm that decides how much torque to give and when, and the full pipeline that trains it, from data collection to model deployment. You’ll take over firmware and controls, with a hands-on handover from the current team in the first weeks. From then on, you’re the lead on firmware and controls, sitting next to the units and the soldiers who use them.
You’ll report to our Engineering Lead and work daily with the software engineer and the field team. This is a lead role: you decide, ship and take responsibility for what is on the device. You’ll thrive in a fast-paced environment and make decisions on your own.
What you’ll do
Make the exoskeleton feel right in every situation a soldier is in, on the move and under load
Improve our machine-learning controls, retrain them with new data, and ship a release every week with notes on what changed and how to test it
Write and maintain the embedded firmware: motor control over CAN, IMU and sensor reading, fault handling, battery and thermal limits, logging, Bluetooth to the app, over-the-air and USB updates
Put reliability first: a unit in the field must never do something unexpected to the person wearing it
Run data collection in Kyiv (treadmill, stairs and ramps, cameras for ground-truth labeling, wearable IMUs, new subjects every week) and make the collect, label, train, release loop fast
Own the full data-to-model-to-firmware pipeline: the training server and its historical dataset, training infrastructure, dataset management and model deployment
Take over our motor driver firmware, test it, make it reliable and own it going forward
Work with the software engineer on what the device records and how the data gets off it, so the app and fleet dashboard can show every test and every unit
Support the field: flash and update units, read logs from tests, explain what the firmware is doing to the field team, and turn what soldiers say into the next release
Join the firmware sync with engineering twice a week
Take ownership and make fast, practical decisions without waiting for detailed direction
What you’ll take over
The full firmware repo and build environment (ESP32, C), the control models and training pipeline, the training server with its complete historical dataset, the data collection setup, the flashing procedure, the bench logging tool and the test playground. You take ownership of the complete data-to-model-to-firmware pipeline, including server administration, training infrastructure, dataset management and model deployment.
What you bring
Has shipped firmware on a robot, drone, exoskeleton, prosthetic or similar: a real device with motors, sensors and a battery, used by people
Strong in embedded C on a microcontroller (ESP32 or similar), motor control, CAN, IMUs and real-time loops, and comfortable with a scope and a soldering iron
Strong in controls, and comfortable with machine learning in a control loop
Can run data collection, training and the training server on your own, end to end, in Python
Senior: decides, ships and takes responsibility for what is on the device
Willing to grind: weekly releases, fixes in hours when a test is blocked, and going to the field when needed
Working English for daily work with international engineers
Based in or willing to relocate to Kyiv, full-time on-site. Any nationality
Nice to have
Gait, biomechanics or legged robotics experience (a big plus)
Good to know
Hardware reaches real operators within days, and we release every week. We’re a small team with one owner per category. Occasional extended hours, weekends and field visits may be needed. Start as soon as possible, with a one-month paid trial. Relocation to Kyiv is covered.
