Junior IOT & Embedded Linux Developer (m/w/d) - IoT Startup

Spend your evenings tinkering with Raspberry Pis, home automation, or custom Linux builds? Imagine doing that every day - and getting paid for it. We're an IoT startup building smart kiosks for autonomous retail, and we need someone who lives and breathes embedded Linux. You'll work hands-on with real hardware — ARM boards, payment terminals, sensors. Formal education doesn’t matter here — proof you can build and fix does. If you can reliably flash an SD card, debug ugly serial bus issues, and write clean Python that runs headless 24/7, we want to talk to you. Come turn your passion project into your career. Tasks Develop and maintain Python edge agents on embedded Linux devices (ARM/Raspberry Pi class) with focus on reliability, telemetry, and updates Integrate payment terminals (e.g. MDB/ZVT) and ensure robust transaction flows, including error recovery Perform signal-level debugging using oscilloscopes and logic analyzers Harden Linux images (systemd services, logging, boot behavior) with reproducible setups (e.g. Ansible) Contribute to testability and documentation through hardware-in-the-loop tests, protocol traces, and troubleshooting guides Requirements Sound knowledge of computing and embedded systems — formal education is welcome but not required. What matters most is that you can demonstrate your skills, whether through GitHub projects, personal builds, open-source contributions, or a portfolio we can review Strong ability for abstract and analytical thinking Fluent in English, German is a plus Nice to have: Experience with MQTT, Docker, D-Bus/NetworkManager, oscilloscope/logic analyzer, or payment terminals/vending protocols Benefits A key role in a fast-growing, highly innovative start-up An agile, international team with colleagues from around the globe Open work culture with flat hierarchies and quick decision-making Dog-friendly office in a central location with great food, shopping, and excellent public transport connections Modern tech stack featuring the latest IoT hardware and software Plenty of creative freedom for your ideas, projects, and personal growth Free EGYM Wellpass membership We are a B2B IoT tech startup focused on a smart kiosk (intelligent fridge) that independently recognizes, tracks, manages, and sells products. Our mission is to use our technology to provide people with simple and fast access to healthy food and other everyday essentials — anytime and anywhere. Our vision: We are developing the future of "Automated Autonomous Retail" and plan to install Livello stations in every large company and in all places where people work, travel, and spend their time. Our customers include companies such as grocery retailers/producers, hotels, restaurants, clinics, universities, delivery services, and catering providers in communal food services.
