Controls Engineer

What you'll do

• You'll support controls for data center cooling products: CDUs, FWUs, chillers, and chiller plant managers. Job entails product development and improvement, field support, factory testing, and troubleshooting. You'll also update as-built drawings and make design changes when needed.

Where you'll work

We are an in-office culture — velocity matters when you're building physical infrastructure, and the best decisions happen in the room. This role is ideally based in our San Francisco, Long Beach, or Houston offices, with full-time onsite expectations outside of bi-weekly WFH Fridays.

That said, we will make exceptions for truly exceptional talent if you live outside one of our hubs. If you're the right person for this role, we'll have a conversation about what works.
