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

Spend your evenings tinkering with Raspberry Pis, home automation, or custom Linux builds? Then this is your position. We're an IoT startup building smart kiosks for autonomous retail. We are hiring for an embedded Linux device-engineering role focused on physical kiosk hardware. We are looking for candidates with demonstrable hands-on experience on ARM/Raspberry-Pi-class devices, peripheral integration, and device-level troubleshooting. The role is centered on embedded systems, hardware interaction, and device robustness.

• Develop and maintain Python edge agents on embedded Linux devices (ARM/Raspberry Pi class) with focus on reliability, telemetry, and updates
• Integrate peripherals and 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

• Solid educational background and expertise in embedded systems. Demonstrate your skills, whether through GitHub projects, personal builds, open-source contributions, or a portfolio we can review
• Experience with headless Python services, Linux service management, device logs, and peripheral integration
• Experience with MQTT, Docker, D-Bus/NetworkManager, oscilloscope/logic analyzer, or payment terminals/vending protocols
• Strong ability for abstract and analytical thinking
• Proficient in English and German

• 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.
