Electronics Engineer / Elektronikentwickler (m/w/d)

We build the machine that makes your gym redundant.

TomFit develops and builds patented training devices — with a small team that has mechanics, electronics, and software under one roof. Now it's moving from small series to mass production.

We are not looking for a theorist, but for someone who thinks systems through, lays and tests circuits themselves, and does not discard wild ideas, but brings them onto the circuit board, into the control cabinet, and into the machine as a whole. Our pace is high, solutions count more than concepts.

What you can achieve with us

• Shape the electronics at TomFit from the ground up: you define the tools, standards, and processes yourself
• Rethink and implement the electronics of our devices — Current Sensing, control cabinet, bus, including the ideas that no one has approved yet
• Bring sensor technology and diagnostics into the devices: what they measure, how they recognize and report errors themselves, how service sees which assembly is acting up. There is still a lot to come in — you will help build it
• Design circuit boards yourself or lead them as a project and commission them in the device
• Help shape the path to mass production: EMC, testability, Second Source, documentation
• Make and take responsibility for technical decisions — directly with suppliers, hardware, and software, without silos

What you bring with you

• Degree in Electrical Engineering and Information Technology (ETH, EPFL, FH or equivalent)
• You have worked physically on things — in your studies, in internships, in the workshop, on real hardware
• You are a doer: schematic, layout, prototype, test, and series — you pull it through to the running device
• 12/24-V circuits are familiar to you
• Interfaces are everyday life: CAN/CANopen, SPI, analog sensor technology, Embedded (STM32, Raspberry Pi or comparable) and enough software so that you speak on an equal footing with the firmware and host side
• Fast and solution-oriented: You prefer to decide rather than maintain processes
• Confident German, everyday English

Nice to have

• Current measurement, EMC, control cabinet wiring, power electronics
• Sensor integration (Hall, vibration, temperature, force) and diagnostic concepts: self-test, error counters, condition monitoring
• Linux on the device, Python/C for testing and evaluation
• AI as a tool in everyday life — and an understanding of what runs on the AI-PC of our devices (sensor technology, coach, inference); no research profile
• Startup or SME experience where you were truly allowed to make decisions

We offer

• Freedom instead of requirement specification ping-pong — decide quickly, build, adjust
• Individual responsibility with direct impact on our product — you close the electronics/informatics gap in the team
• Flexible working hours and fair compensation
• Small young team, open culture, short paths
• AI tools in daily business — AI-First is practice for us, not a buzzword
• Stay fit — free training on our devices during working hours, for everyone in the team
• Co-shaping a growing company with real health impact
