As a Controls Engineer, Transformers at Giga Energy, you'll design the control, monitoring and protection systems on our liquid-filled transformers and make sure each one is built and tested to spec. You'll create the schematics, wiring diagrams and I/O lists for temperature monitoring, cooling, tap changers, switches and fusing, support factory testing, and own root-cause fixes when issues show up in the field. If you like hands-on engineering that bridges design, the factory floor and the field, this is your role.
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.

Oil and winding temperature indicators (OTI / WTI)
Cooling control logic (fans, pumps)
Alarm and trip circuits
Monitoring and SCADA interfaces (as applicable)
Design and support transformer control and protection systems, including:
Off-circuit tap changers (position indication, interlocks, control wiring)
Loadbreak switches and associated operating mechanisms
Primary and secondary fusing, including coordination with transformer impedance and system requirements
