What does a controls engineer specializing in PLC programming do?

A Controls Engineer with expertise in PLC (Programmable Logic Controller) programming is responsible for designing, developing, and maintaining automated control systems used in manufacturing and industrial environments. They program PLCs to monitor and control machinery, ensuring equipment operates safely and efficiently. This role often involves troubleshooting system issues, integrating new automation technologies, and collaborating with other engineers to optimize production processes.

What are the typical challenges faced when working as a controls engineer specializing in PLC programming?

Controls Engineers specializing in PLC programming often encounter challenges such as troubleshooting complex automation systems under tight deadlines, adapting to rapidly evolving technologies, and ensuring seamless integration between hardware and software components. They may also need to coordinate with multidisciplinary teams, including electricians, mechanical engineers, and production staff, to implement solutions efficiently. Staying updated on industry standards and maintaining strong documentation practices are essential for long-term project success and career growth.

What are the key skills and qualifications needed to thrive as a controls engineer specializing in PLC programming, and why are they important?

To thrive as a Controls Engineer in PLC programming, you need a solid background in electrical engineering, automation, and industrial control systems, often supported by a relevant degree. Proficiency with PLC platforms (such as Allen-Bradley or Siemens), HMI/SCADA systems, and programming languages like ladder logic is essential, and certifications like Siemens Certified Programmer or Rockwell Automation credentials are highly valued. Strong problem-solving, attention to detail, and effective communication skills help you design, troubleshoot, and collaborate on complex automation projects. These skills ensure reliable, safe, and efficient system operation, which is critical for manufacturing productivity and minimizing downtime.

What is the difference between Controls Engineer Plc Programming vs Controls Engineer Electrical Design?

Job description

About Fluidstack
We exist to make humanity more free. For most of human history, you farmed or you starved. Technology gave people more time for the things they wanted to do, instead of things they had to do. Powerful AI will be the biggest lever for human choice we've ever built - but only if models are aligned with what humanity actually wants. There are groups building AI who don't share these goals. Whoever deploys frontier compute infrastructure fastest will decide whether AI expands human freedom or shrinks it.
We're singularly focused on delivering 10 to 100s of GWs of compute faster than anyone else, rethinking every layer of the stack. We acquire power, design and build data centers, and operate them - with teams spanning hardware and software. Speed and scale are our key differentiators. Come be a part of building civilization-scale infrastructure for AI.
We hire people who care deeply about this problem space. If that is you, please apply!
How We Operate
  • Extreme ownership. Full autonomy. Own things end to end often taking on scope outside your core role without being asked to get things done.
  • Velocity. We drive everything forward as fast as possible.
  • First principles. Challenge every assumption. Zero analogy thinking, no egos, the best idea wins.
  • Love of the game. The frontier of AI is the most interesting problem of our time. We put in long hours at high intensity to push the frontier forward.

The Controls Team
Examples of key problems the team is working on
  • Deliver the controls behind 10s to 100s of GWs of data centers this decade.
  • Own real-time load control and MEP and behind-the-meter integration.
  • Automate Level 4 and Level 5 commissioning.
  • Drive autonomous, robotic deployment.

Role Scope
  • Develop and test template PLC programs for the standard mechanical equipment across every data center, chiller skids, fan wall units, CRAHs, and the rest, so one validated program deploys fleetwide instead of being rebuilt site by site.
  • Write portable code across mixed PLC hardware, Siemens, Codesys, and virtualized PLCs, so a program built once runs regardless of the controller underneath it.
  • Develop and tune sequences of operations with the controls and mechanical teams, then implement those SOOs directly in PLC code.
  • Install and wire PLCs and sensors in a lab environment, standing up real hardware to validate programs before they ever run on live equipment.
  • Debug programs against real IO and failure conditions on the bench so field commissioning becomes a verification step, not a debugging session.
What We're Looking For
The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly, tell us where you would.
  • You've written and tested PLC programs for mechanical equipment, chillers, air handlers, pumps, or similar, and watched them run on real hardware, not only in simulation.
  • You've programmed across more than one PLC platform, Siemens, Codesys, or virtualized environments, and you don't treat one vendor's toolchain as the boundary of what's possible.
  • You've turned a sequence of operations into working PLC code, and you've caught the gaps and contradictions in an SOO before they reached the controller.
  • You've wired PLCs, IO, and sensors yourself, and you've traced a fault down to the physical layer when a program that looked right on screen misbehaved on the bench.
  • You write structured, reusable code that the next engineer can read, so the templates you build get reused rather than rewritten.
  • You test against failure and edge cases, not just the expected path, and you find the problems in the lab instead of in a running data center.
  • Bonus: Data center mechanical systems (chiller plants, CRAH/CRAC, fan wall units). Structured Text and the IEC 61131-3 languages. BMS or SCADA integration over BACnet and Modbus. Hardware-in-the-loop or virtualized PLC testing.

We are committed to pay equity and transparency.
