OverviewTonal is looking for a Senior Power Electronics Firmware Engineer to develop the firmware for our motor drive and power systems. That drive generates up to 250 pounds of digital weight, so its firmware defines how Tonal feels to every member. You’ll contribute at every stage, from concept, prototyping, and bring-up through validation and high-volume production.

You’ll join the Firmware team in our Hardware department, working closely with electrical, mechanical, and software engineers. Together, you’ll tackle challenges that span motor control, power conversion, thermal limits, and member safety. Develop and improve motor control and power management firmware that makes Tonal’s digital weight feel smooth and responsive Bring up and debug current boards in the lab with the electrical team Test and tune motor performance, and help build the tools and automated tests that validate each release Support manufacturing test and calibration, and help investigate issues from the field Work with software, mechanical, and product teams to turn member feedback into firmware improvements Take part in design and code reviews, and help improve how the team builds and ships firmware 5+ years of embedded firmware development, including 3+ years focused on motor control or power electronics experience in C++ and Python is also valuable Solid power electronics fundamentals: inverters,



DC-DC converters, PWM techniques such as SVPWM, gate drivers, current and voltage sensing, and thermal behavior Experience designing discrete‑time control loops, filters, and observers, and modeling them in MATLAB/Simulink or Python Experience with motor‑control MCUs or DSPs (e.Creative problem solver who isn’t afraid to push boundaries and think differently, with high attention to detail Experience with functional or appliance safety standards, such as IEC 60730 (Class B software), IEC 60335, IEC 61508, or ISO 26262 Experience managing regenerative energy in motor drives, such as braking resistor control and DC bus regulation Experience with digitally controlled power conversion, such as PFC or DC-DC stages Experience with unit testing, software- and hardware-in-the-loop (SIL/HIL) testing, Git, and CI tools such as Jenkins Experience with EMC/EMI and safety compliance testing for motor drives Experience shipping high-volume consumer hardware Tonal is committed to meeting the diverse needs of people with disabilities in a timely manner that is consistent with the principles of independence, dignity, integration, and equality of opportunity.

All requests will be addressed and responded to in accordance with Tonal’s Accessibility Policy and local legislation. #
