About the role

  • 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.

Responsibilities

  • As a Senior PLC Engineer, you'll own the controls software that keeps our infrastructure online.
  • This is a hands-on build role.
  • Design, develop, test, and commission PLC programs on Siemens (TIA Portal, S7-1500/1200) and/or Rockwell/Allen-Bradley (Studio 5000, ControlLogix/CompactLogix) platforms, using IEC 61131-3 languages (Structured Text and ladder), for cooling and mechanical plant equipment: CDUs, chillers, hydraulic skids, fan walls, DOAS, and pumps.
  • Develop the supervisory logic for the Master Plant Controller, including equipment staging, lead/lag, setpoint reset, failover, and plant-level coordination across multiple skids.
  • Build and maintain the SCADA/HMI layer (Siemens WinCC, Rockwell FactoryTalk View, or Ignition): operator screens, alarming, trending, historian, and access control.
  • Build process simulations and digital twins (Siemens PLCSIM Advanced / SIMIT, Rockwell Studio 5000 Emulate / Emulate3D, or scripted models) to validate logic and tune control loops before site deployment.
  • Lead field commissioning, startup, and loop checks. Troubleshoot live systems and drive issues to resolution.
  • Build the general-purpose software around the controls stack: data pipelines, monitoring and telemetry services, edge and cloud integrations, internal tooling, and automation that connects plant data to the rest of Giga's systems.

Requirements

  • 5+ years programming industrial PLCs and SCADA/HMI systems in production environments.
  • Proven SCADA/HMI development experience (Siemens WinCC, Rockwell FactoryTalk View, Ignition, or comparable platform), including alarming, historian, and trending.
  • Experience programming controls for mechanical, process, or HVAC plants (pumps, valves, chillers, heat exchangers, air handling).
  • Track record of commissioning systems on live equipment, with a rigorous, safety-first mindset.
  • Excellent written and verbal communication, with the ability to work directly with controls engineers, mechanical engineers, and field technicians.
  • Experience with liquid cooling, data center cooling, or high-density compute thermal management.
  • Familiarity with process simulation and digital twins (SIMIT, PLCSIM Advanced co-simulation, MATLAB/Simulink).
  • Hands-on Ignition (Inductive Automation) experience, including Python/Jython scripting.
  • Ability to read and interpret P&IDs, electrical schematics, and I/O schedules.
  • Experience standing up controls programs from scratch in a fast-moving, greenfield setting.

Nice to have

  • Deep hands-on experience with Siemens (TIA Portal, S7-1500/1200) and/or Rockwell/Allen-Bradley (Studio 5000, ControlLogix/CompactLogix), fluent in Structured Text and not just ladder.
  • Experience across both platforms is a strong plus.

Skills

  • Operate comfortably in ambiguous, unstructured environments and solve problems where established processes don't yet exist.

Benefits

  • Subsidized health, dental, and vision insurance
  • Equity (options) in a rapidly growing startup
  • Parental leave
  • Healthcare and Dependent Care Flexible Spending Accounts (FSA) or Health Savings Account (HSA)
  • Commuter benefits
