Infrastructure Engineer

About the role

ElevateOS integrates with 20+ smart-device ecosystems — keyless entry, locks, cameras, switches, thermostats. Every integration is validated against physical hardware before release. We're hiring the person who owns that pipeline: the servers and environments behind it, the lab networking, and the infrastructure that keeps everything running.

You'll set up and maintain the servers, environments, and networking behind our device integration pipeline, working directly with the development team and CTO with real autonomy — you decide how the infrastructure and tooling evolve. The role centers on server/infra ownership and diagnostic problem-solving, with IoT and hardware 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, and US-based. Our stack is JavaScript end to end: React, Node.js, and React Native.
