Remote Inductive Automation Ignition Jobs (NOW HIRING)

As a Senior PLC Engineer, you'll own the controls software that keeps our infrastructure online. This is a hands-on build role. You'll take an architecture from concept to commissioned, running system, programming the PLCs and SCADA and writing the software, services, and tooling around them.

This is a remote role, with a preference for candidates based in Dallas, TX. Regardless of home base, you must be willing to travel frequently to our project and job sites for installation, startup, and commissioning.

• 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.
• Write robust safety logic, interlocks, and alarm strategies for pressurized and high-power equipment, and uphold a safety-first engineering standard.
• Integrate OEM-controlled equipment such as chillers and DOAS over Modbus TCP, BACnet, OPC UA, EtherNet/IP, and PROFINET, defining and validating register and object maps.
• 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.
• Apply real software engineering practices to controls work: version control, code review, modular and reusable function-block libraries, and clear naming and documentation standards.
• 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.
• Translate the controls engineer's architecture and sequence-of-operations into working, well-structured, maintainable code.
• Operate comfortably in ambiguous, unstructured environments and solve problems where established processes don't yet exist.

• 5+ years programming industrial PLCs and SCADA/HMI systems in production environments.
• 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.
• Proven SCADA/HMI development experience (Siemens WinCC, Rockwell FactoryTalk View, Ignition, or comparable platform), including alarming, historian, and trending.
• Strong command of industrial communication protocols such as EtherNet/IP, PROFINET, Modbus TCP, OPC UA, and BACnet.
• 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.
• Willingness to travel to project sites for installation and commissioning.

• 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.
• Functional safety experience (PROFIsafe, CIP Safety, GuardLogix or other safety PLCs, SIL-rated logic).
• Industrial networking depth, including VLANs, redundancy, edge devices, and secure OT network design.
• Ability to read and interpret P&IDs, electrical schematics, and I/O schedules.
• Strong general-purpose software engineering skills, fluent in at least one modern language (Python, C#, C++, Go, or similar), and comfortable with Git, testing, and clean code structure.
• Experience building edge-to-cloud data pipelines or plant telemetry and observability systems.
• Background bridging IT and OT, bringing modern software practices (CI/CD, infrastructure-as-code, containerization) into a controls environment.
• Experience standing up controls programs from scratch in a fast-moving, greenfield setting.

• 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
