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

<p>Spend your evenings tinkering with Raspberry Pis, home automation, or custom Linux builds? Imagine doing that every day - and getting paid for it.</p> <p>We&#39;re an IoT startup building smart kiosks for autonomous retail, and we need someone who lives and breathes embedded Linux. You&#39;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.</p> <p>Come turn your passion project into your career.</p> <h2 id="tasks">Tasks</h2> <ul> <li>Develop and maintain Python edge agents on embedded Linux devices (ARM/Raspberry Pi class) with focus on reliability, telemetry, and updates</li> <li>Integrate payment terminals (e.g. MDB/ZVT) and ensure robust transaction flows, including error recovery</li> <li>Perform signal-level debugging using oscilloscopes and logic analyzers</li> <li>Harden Linux images (systemd services, logging, boot behavior) with reproducible setups (e.g. Ansible)</li> <li>Contribute to testability and documentation through hardware-in-the-loop tests, protocol traces, and troubleshooting guides</li> </ul> <h2 id="requirements">Requirements</h2> <ul> <li>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</li> <li>Strong ability for abstract and analytical thinking</li> <li>Fluent in English, German is a plus</li> <li><strong>Nice to have:</strong> Experience with MQTT, Docker, D-Bus/NetworkManager, oscilloscope/logic analyzer, or payment terminals/vending protocols</li> </ul> <h2 id="benefits">Benefits</h2> <ul> <li>A key role in a fast-growing, highly innovative start-up</li> <li>An agile, international team with colleagues from around the globe</li> <li>Open work culture with flat hierarchies and quick decision-making</li> <li>Dog-friendly office in a central location with great food, shopping, and excellent public transport connections</li> <li>Modern tech stack featuring the latest IoT hardware and software</li> <li>Plenty of creative freedom for your ideas, projects, and personal growth</li> <li>Free EGYM Wellpass membership</li> </ul> <p>We are a B2B IoT tech startup focused on a smart kiosk (intelligent fridge) that independently recognizes, tracks, manages, and sells products.</p> <p>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.</p> <p>Our vision: We are developing the future of &quot;Automated Autonomous Retail&quot; and plan to install Livello stations in every large company and in all places where people work, travel, and spend their time.</p> <p>Our customers include companies such as grocery retailers/producers, hotels, restaurants, clinics, universities, delivery services, and catering providers in communal food services.</p>
