IoT Integration Engineer

IoT Integration Engineer (Smart Home Devices, PropTech product) Remotely from Krakow or near (with rare occasional onsite presence) B2B contract full-time About the role ElevateOS integrates with 20+ smart-device ecosystems — keyless entry, locks, cameras, switches, thermostats, etc. Every integration is validated against physical hardware before release. We're hiring the person who owns that pipeline: the physical device lab, the hardware itself, and the environments and networking that keep everything running. You'll set up and maintain the smart devices, test environments, and networking behind our device integration pipeline, working directly with the development team and CTO with real autonomy — you decide how the lab and tooling evolve. The role centers on hands-on hardware ownership and diagnostic problem-solving, with servers and infrastructure as part of the environment you support. About ElevateOS ElevateOS has been improving the resident experience for over seven years. We built a single, all-in-one platform that lets property managers and resident staff work together, replacing multiple confusing apps with one intuitive solution. The product is stable, growing, US-based. Our stack is JavaScript end to end: React, Node.js, and React Native. Requirements: Hands-on experience with smart home / IoT devices — locks, cameras, sensors, hubs, thermostats, or similar Solid Linux and networking fundamentals — comfortable in a terminal, SSH, logs, DNS/DHCP/port-level debugging Strong at reading documentation and code (JavaScript/TypeScript) to independently identify where a problem is Based in or near Kraków (hardware will be hosted at your home - a standard workspace, no additional room is needed) Solid commercial technical experience (not junior) Good English communication. What you'll own The physical device lab — smart locks, access-control hardware, cameras, switches — in Kraków Setup, configuration, firmware updates, troubleshooting, and inventory Test environments and servers — install, configure, and maintain the local and staging environments our integrations run against; adjust configurations live during debugging sessions with developers. Lab networking — device connectivity (Wi-Fi, BLE, Zigbee/Z-Wave), router and network configuration, and remote access so the dev team can reach devices and environments from anywhere. Integration testing — install iOS/Android builds, run end-to-end tests against physical devices, API testing, reproduce and isolate bugs, verify fixes with the team. Documentation — device matrix, environment runbooks, test protocols, and findings. Occasional in-person device handoffs in Kraków.
