À propos de cette offre
We're TomFit, an AI-native physical health provider, building our own training machine and studios, scaling out of Zürich. We combine a new kind of strength training machine, the TomBot, with a software platform and AI to let people create, execute, and monitor a personal training regime that actually adapts to them and their needs. A deeply integrated diagnostics capability allows us to tailor the exercise to the user for highly targeted, effective, and efficient training. As a small, multi-disciplinary team of 25 people across engineering, product, and operations, we are currently operating three hubs with more than a dozen machines deployed. We take a pragmatic, dynamic, and fast approach to building and scaling an AI-native health company. Hardware, software, and intelligence in one product. The hardware exists. The platform exists. Now we want to evolve the intelligence to create an experience people fall in love with. We are looking for a senior engineer to lead the development of our TomFit Coach: the brain that turns sensor data, training history, and a user's goals into real, personalised coaching. Not a chatbot bolted onto a fitness app, but a coach that knows what you did yesterday, watches what you do today, and thinks about what you should do tomorrow.
What you'll do
- Own the intelligence layer of a real-world AI fitness product – from the model layer and orchestration logic to how it shows up in our apps
- Design and build the agentic systems that power the coach
- Integrate them across our platform
- Work closely with the rest of the team to make sure the product feels coherent across the machine, the app, and the coach
- Evolve the intelligence to create an experience people fall in love with
What we need from you
- An experienced fullstack engineer who can show us real products you have worked on – ideally with a hardware component
- Our current stack is Java, React, Flutter, and Kotlin Multiplatform – no need to be an expert, but you should be comfortable diving into them all
- Real hands-on experience both building with AI and building AI-based applications – this is at the heart of the role
- You can work on-site with us in Zürich Stettbach or Kraków – test directly with the TomBot, observe training sessions, and iterate in the studio
- Excellent English; German is a big plus
- You are a creative, pragmatic, solution-driven engineer focused on getting this to market fast

If this sounds interesting, please send us a short video (2 to 3 minutes) where you walk us through 1 to 2 things you have recently built. Tell us what you tried, what you learned, what surprised you, and what you would do differently next time. We care more about how you think than how polished the demo is.
