About The Position

Johnson Controls is building the next generation of intelligent building systems for the world's most demanding environments, hyperscale data centers. We're looking for a technically versatile engineer who loves both crafting intuitive user interfaces and engineering the backend systems that power them. This role sits inside our Data Center Controls Innovation Engineering team at our Controls Product Development Center in Glendale, WI. You'll be embedded in a collaborative lab and software environment working alongside experienced engineers on middleware platforms, web applications, and building automation systems deployed in critical infrastructure globally. If you're someone who cares about both how a system works under the hood and how a user experiences it on screen, this is the role for you. This position is 100% on-site at our new Controls Product Development Center and Lab in Glendale, WI, where you'll collaborate closely with cross-disciplinary teams and work hands-on with real products. The role may include up to 20% travel.

• Familiarity with relational or time-series databases and writing queries (SQL, InfluxDB, or similar)
• Basic experience with containerization and deployment tooling (Docker, CI/CD pipelines)
• Comfortable working in a Linux/Unix environment and using Git for version control
• Strong problem-solving instincts; you dig into issues and follow threads across the stack rather than waiting for someone else to solve them
• Organized and clear communicator; you can write a concise technical summary and present it to a room

• Must be authorized to work in the U.S.; no sponsorship available
