Controls Engineer

Role overview Own the design, development, and commissioning of control systems for mission-critical AI data center infrastructure. The role spans PLC and HMI programming, panel design, control schematics, and I/O architecture, ensuring complex systems work reliably and stay running in environments that cannot afford downtime.

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 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, site acceptance testing, and commissioning activities. - 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, with Rockwell Automation Suite preferred. - Experience designing control panels and producing control schematics using AutoCAD. - Solid understanding of control systems principles including loop and PID control, with building automation cooling systems 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 such as Ethernet/IP, Modbus TCP, or Modbus RTU. - Bachelor's degree in Electrical Engineering, Controls Engineering, or a closely related field, or equivalent hands-on experience.

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

Benefits and work setup - In-office culture with locations in San Francisco, Long Beach, and Houston; full-time onsite expectations outside of bi-weekly WFH Fridays, with flexibility for exceptional candidates outside hub cities. - Subsidized health, dental, and vision insurance. - Equity options in a rapidly growing startup. - 401(k) with 4% employer match. - Unlimited PTO and parental leave. - Healthcare and Dependent Care FSA or HSA options, plus commuter benefits where applicable. - Periodic in-person team and company on-sites.
