PLC & Controls Engineer

Role overview

Hyetron Energy is looking for a practical, hands-on PLC and controls engineer to help build and commission electrolyser test benches. The position centers on PLC development, HMI creation, electrical integration, power supply control, industrial networking, and end-to-end system commissioning. You will collaborate with the technical team to implement automation logic, control sequences, safety protections, and communication interfaces for advanced hydrogen equipment.

What you will do

• Create and commission PLC applications using Siemens S7-1200 and TIA Portal.
• Design HMI pages for live monitoring and operator control.
• Connect and bring up PLCs, HMIs, power supplies, sensors, actuators, and industrial communication links for electrolyser test benches.
• Set up analog and digital input/output configurations.
• Develop control logic, alarm handling, safety interlocks, and automated test sequences.
• Assemble and commission electrical control panels.
• Assist with hands-on integration, testing, troubleshooting, and final commissioning of systems.

What we are looking for

• A B.Tech, B.E., or diploma background in Electrical, Electronics, Instrumentation, Mechatronics, or a related discipline.
• About 1 to 2 years of practical PLC programming experience for one section of the role requirements, and 3 to 5 years of PLC/automation experience for the broader experience preference mentioned in the description.
• Hands-on experience with Siemens S7-1200 PLCs and TIA Portal.
• Working knowledge of PLC programming, I/O setup, alarms, interlocks, and automation sequencing.
• Good familiarity with industrial communication protocols such as Modbus RTU/TCP, Profinet, Profibus, Ethernet/IP, RS485, RS232, and CAN.
• Experience integrating sensors, VFDs, actuators, power supplies, and other industrial hardware.
• Comfort with electrical schematics, panel wiring, and commissioning activities.
• Strong troubleshooting and problem-solving ability.

Preferred experience

• Exposure to WinCC, SCADA, LabVIEW, or Python.
• Experience with data acquisition and logging systems.
• Background in process automation or machine automation.
• Exposure to fuel cells, electrolyser systems, battery systems, or renewable energy technologies.

Growth and learning opportunity

This is not limited to a conventional PLC coding role. You will gain practical exposure to hydrogen and electrolyser technology, industrial automation, power electronics, energy systems, Battery Energy Storage Systems (BESS), Battery Management System (BMS) integration, and renewable or grid-connected systems. As the company expands, the role can open a path into Power Systems Engineering, including battery systems, BMS, power electronics, hydrogen applications, and renewable energy systems.
