Siemens PLC Programmer Needed – Helium Plant Support
We are looking for an experienced Siemens PLC programmer to provide programming and technical support for an operating helium processing plant.
The control system is based on Siemens PLC hardware and is programmed using TIA Portal. The successful freelancer should be comfortable reviewing existing programs, troubleshooting operating issues, making controlled logic changes, and supporting plant personnel remotely.
Scope of Work
Review and understand the existing Siemens PLC program
Troubleshoot PLC logic, communications, instrumentation, and process-control issues
Modify ladder logic, function blocks, data blocks, alarms, interlocks, and sequences as required
Assist with Siemens HMI programming and troubleshooting when needed
Support analog instrumentation, valves, motors, VFDs, compressors, and process equipment
Provide remote support during commissioning, shutdowns, startups, or plant operating issues
Document all program changes and maintain reliable backups
Explain the Siemens program structure and changes to our existing automation personnel
Required Experience
Strong experience with Siemens S7 PLCs
Proficient with Siemens TIA Portal and STEP 7
Experience with S7-1200 or S7-1500 PLCs
Strong understanding of OBs, FBs, FCs, data blocks, instance data blocks, and symbolic addressing
Experience troubleshooting PROFINET and industrial communications
Experience with process plants, oil and gas, gas processing, refrigeration, compressors, or similar industrial facilities
Ability to safely support a live operating facility
Strong English communication and documentation skills
Experience with helium processing, cryogenic systems, gas separation, compressor controls, or Siemens HMI systems would be a major asset.
Working Arrangement
This will initially be remote, project-based support, with the possibility of ongoing work for the right person. Availability during North American Mountain Time business hours is preferred.
When applying, please include:
Your Siemens PLC and TIA Portal experience
The Siemens PLC models and TIA Portal versions you have worked with
Examples of similar process-plant projects
Your hourly rate
Your availability
Whether you can provide urgent or after-hours support when required
Please only apply if you have substantial hands-on Siemens PLC experience in operating industrial facilities.
