IoT Platform Engineer

IN SHORT

Are you ready to build the backbone of our smart workplace technology? As our new IoT Platform Engineer (100%) in Zurich, you will own the transition of our hardware fleet into a highly reliable, streamlined system. FELFEL puts smart fridges and coffee machines in offices across Switzerland and the US, and every line of code you write will run in a real workplace, serving real people every day.

YOUR RESPONSIBILITIES

• Own the device runtime on our fridges and coffee machine controllers (Gavettis) end to end, managing everything from zero-touch provisioning, device bootstrap, call-home and on-device applications.
• Drive the consolidation of our fleet management onto a single platform, making the architectural choices and defending them.
• Reduce the number of programming languages running on the edge, bringing our cloud and device environments closer together.
• Partner with the Head of Engineering to spec the next generation of fridge and Gavetti hardware, pick vendors, and define the software contracts.
• Manage and evolve vendor relationships and integrations for our vendors and badge reader suppliers.
• Act as the ultimate reality check on the engineering team for what is actually running and succeeding in the field.

YOUR PROFILE

• 5+ years of experience building production systems, with a proven track record of shipping and operating a real fleet of devices in production (handling real users, outages, and OTA updates).
• Strong working knowledge of edge platform concerns, including networking (VPNs, NAT, flaky links), Linux and Android on small hardware, OS-level debugging, and observability for offline-tolerant systems.
• Comfort and proficiency across at least two of the following languages: C#, Go, or Kotlin, with a willingness to standardize.
• Deep understanding of hardware as an interface, with the ability to navigate Modbus, USB, serial connections, sensor datasheets, and vendor SDKs.
• Experience with Balena, Azure IoT Hub, KubeEdge, Kubernetes, Docker, or containerized workloads is a strong plus.
• Familiarity with commercial appliance ecosystems (like coffee machines or vending) and enough electronics literacy to read a datasheet and ask the right questions.
• Pragmatic problem-solving mindset—you would rather standardize than invent, and you choose the boring, reliable tool over the purely interesting one.
• Fluency in English (our working language); German, Spanish, or other languages are a welcome bonus.
• Non-smoker - we don't want you to smell like cigarettes, neither at work nor at customer meetings. After all, FELFEL is about good food.
• Valid work permit or Swiss passport.
