IoT / Smart Home Engineer

Job Description

The company is looking for an experienced IoT / Smart Home Engineer to support a high-impact cross-protocol IoT project starting immediately. The goal is to extract and normalize data across multiple building bus systems and smart home protocols, including standard telemetry and device-level metadata such as firmware versions, topology information, capabilities, and discovery data.

Responsibilities

• Analyze and, where necessary, reverse-engineer relevant protocol layers
• Design a protocol-agnostic data structure combining telemetry and device metadata
• Develop and maintain connectors/adapters for data extraction
• Focus on discovery, device fingerprinting, mapping, and normalization
• Document realistically extractable data per protocol

Profile

• Solid understanding of building automation (bus systems, gateways, commissioning, topologies)
• Experience with several protocols such as KNX, Modbus, BACnet, Zigbee/Z-Wave, Matter/Thread, MQTT
• Strong programming skills (ideally Python, Node.js, or Go)
• Experience with Docker, REST APIs, and tools like Wireshark
• Ability to understand and clearly document encoding/decoding, addressing, and protocol internals
• English or German language skills

What to Expect

The organization is a startup building this platform from the ground up. You’ll work closely with the core team and contribute to the continuous development of the platform’s technical structure. If you enjoy working on technically ambitious projects in a focused startup environment, this role may be a great fit for you.
