Controls Engineer

Why Join Giga

• The Pace: We're building at a speed most companies talk about but never actually operate at. If you've been bored somewhere else, you won't be here.
• The Impact
  :
  Every person at Giga touches the work that matters. No layers, no waiting for approval chains. You'll see your fingerprints on what we ship.
• The Team: A team of operators defining the future of AI infrastructure. We recruit A-players from the most innovative companies in the world, and they choose Giga because the work here means more.
• The Moment
  : AI doesn't run without power, and that's us. Giga is the picks and shovels behind the AI revolution. This industry is about to explode, and you'll be in the room where it's already happening.

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.

This role is based out of one of our offices (San Francisco, CA / Long Beach, CA / Houston, TX). We work in person because the best engineering happens when smart people are in the same room.

• 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& 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

• 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&, 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)

• 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

• Subsidized health, dental, and vision insurance
• Equity (options) in a rapidly growing startup
• 401(k) with 4% employer match
• Unlimited PTO
• Parental leave
• Healthcare and Dependent Care Flexible Spending Accounts (FSA) or Health Savings Account (HSA)
• Commuter benefits
• Team…
