Controls Engineer, Transformers

What you’ll do
We’re hiring a Controls Engineer to design and support the control, monitoring, and protection systems used in Giga’s liquid-filled transformers. You’ll ensure that transformer accessories and control schemes operate reliably, meet customer requirements, and integrate cleanly with manufacturing and testing.
