Electronics Engineer

TomFit AG; Dübendorf; On-site; CHF 110,000 - 150,000; Full time

Job summary

TomFit AG in Dübendorf is building market-shaping training machines. We seek an Electronics Engineer (m/f/d) who loves hardware, tests circuits, and turns bold ideas into real boards and cabinets. You will shape electronics from the ground up and own the path from prototype to series.

You will rebuild electronics of our machines, handle current sensing, cabinet wiring, and the bus. You’ll design boards or lead that work, ensure EMC and testability, and document the journey.

Qualifications

• Degree in electrical engineering or equivalent with hardware practice.
• Experience building real hardware from prototype to series.
• Familiar with 12/24 V circuits and hardware testing.
• Proficient with CAN/CANopen, SPI, analog sensors and embedded platforms.
• Excellent project ownership and collaboration with suppliers.

Responsibilities

• Shape electronics from ground up: set tools, standards, working methods.
• Rebuild electronics of machines: current sensing, cabinet, bus to series.
• Bring sensing and diagnostics into machines and fault reporting.
• Design boards or lead that work and bring into machine.
• Shape path into series: EMC, testability, second source, documentation.
• Make technical decisions with suppliers, hardware and software.

Job description

Electronics Engineer (m/f/d)

We build the machine that makes the gym obsolete.

TomFit develops and builds patented training machines. A small team, with mechanics, electronics and software under one roof. We are moving from small batches into series.

We are not looking for a theorist. We want someone who thinks a system through, lays out and tests the circuit themselves, and puts a wild idea on the board, into the cabinet and into the machine. The pace is high. A working solution counts more than a concept.

What you will do

• Shape the electronics at TomFit from the ground up: you set the tools, the standards and the way of working
• Rebuild the electronics of our machines — current sensing, cabinet, bus — and take new ideas from prototype and release into series
• Bring sensing and diagnostics into the machines: what they measure, how they spot and report a fault, how service sees which assembly is failing. A lot of this is still open. You build it with us
• Design boards yourself, or lead that work, and bring them up in the machine
• Shape the path into series: EMC, testability, second source, documentation
• Take the technical decisions and own them, with suppliers, hardware and software, no silo

What you bring

• A degree in electrical engineering (ETH, EPFL, university of applied sciences) or an equivalent background with real hardware practice
• You have worked on physical things: in your studies, an internship, a workshop, on real hardware
• You build: schematic, layout, prototype, test and series, through to a running device
• 12/24 V circuits are familiar
• Interfaces are everyday work: CAN/CANopen, SPI, analog sensors, embedded (STM32, Raspberry Pi or similar), and enough software to talk to firmware and the host side as a peer
• Fast and pragmatic, with as much test, documentation and structure as series production needs
• You run your own projects, including suppliers and dates, and you escal… early when something is blocked
• English for the daily work

Nice to have

• . Useful with the workshop and the team, not a requirement
• Current sensing, EMC, cabinet wiring, power electronics
• Sensor integration ( , vibration, temperature, force) and diagnostics: self-test, error counters, condition monitoring
• Linux on the device, or C for test and analysis
• AI as a tool in daily work, and an understanding of what runs on the AI PC in our machines (sensing, coach, inference). Not a research profile
• Startup or SME experience where you actually got to decide

We offer

• Room to decide, build and adjust, without a specification going back and forth
• Ownership with a direct effect on the product. You close the electronics and software gap in the team
• Flexible hours and fair pay
• A small, young team, an open culture, short paths
• AI tools in daily work. AI-first is how we work
• Stay fit: free training on our machines during working hours, for the whole team
• A growing company with a real effect on health

Show us something you built yourself: a PCB, an embedded project, prototype photos, GitHub, or five sentences on a problem you solved. No portfolio required.
