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

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.

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

Benefits

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 on-sites where all offices come in–person to collaborate
