Controls Engineer

What you'll do

As a Controls Engineer at Giga, you will own the design, development, and commissioning of control systems for mission-critical AI infrastructure. From PLC/HMI programming and panel design to control schematics and I/O architecture, you’ll be the person who makes the systems actually work — and keeps them running. If you love getting into the details of how complex systems talk to each other and take pride in building things that can’t afford to go down, this is your role.

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.

Responsibilities

• Design and develop PLC and HMI programs for building automation and facility control systems
• Design control panels and produce detailed control schematics from concept through construction-ready documentation
• Develop and maintain network designs across a range of communication protocols including Ethernet/IP, Modbus TCP, and Modbus RTU
• Configure and commission VFD drive controls for motors, pumps, and HVAC systems
• Read and interpret P&ID diagrams to translate process requirements into control logic — including valve sequencing, motor control, and pump staging
• Collaborate with mechanical, electrical, and systems engineers to integrate controls into broader facility infrastructure
• Support factory acceptance testing (FAT), site acceptance testing (SAT), and commissioning activities 
• Continuous improvement on existing Controls and BMS design and scale as needed.
• Troubleshoot control system issues in the field and drive resolution with minimal supervision
• Maintain accurate as-built documentation, program backups, and engineering records

Requirements

• 3+ years of hands-on PLC and HMI programming and commissioning experience. Rockwell Automation Suite Preferred 
• Experience designing control panels and producing control schematics using AUTOCAD
• Solid understanding of general control systems principles including loop and PID control, Cooling systems control with building automation experience strongly preferred
• Working knowledge of VFD drive configuration and control. Allen Bradley and ABB drives a plus.
• Ability to read and work from P&ID diagrams, including valve functions, motor control, and pump control logic
• Familiarity with I/O design and at least one industrial communication protocol (Ethernet/IP, Modbus TCP, or Modbus RTU)
• Strong learning agility — you pick up new platforms, tools, and systems quickly and without hand-holding
• Bachelor’s degree in Electrical Engineering, Controls Engineering, or a closely related field (or equivalent hands-on experience)

Bonus points

• Experience with data center cooling control systems or other mission-critical facility environments (hospitals, colocation, power generation)
• Knowledge of network architecture and industrial cybersecurity practices for OT/ICS environments
• Experience with additional communication protocols (BACnet, Profibus, PROFINET, OPC-UA)
• Familiarity with SCADA systems and historian platforms. Ignition experience preferred.
• Experience working in fast-paced build environments where schedules are tight and priorities shift
