PLC / Automation Engineer – Siemens TIA Portal

Location: Italy

Contract Length: 3–6 months

Start: ASAP

Working Pattern: 3-shift rotation

Indicative Rate: Approx. 60/hour

Accommodation: Provided / paid for

Travel: Flights / travel costs covered

The Opportunity

We are looking for PLC / Automation Engineers for a hands-on industrial automation troubleshooting project in Italy .

The main technical requirement is strong experience with Siemens PLC systems and TIA Portal , with some additional exposure to Omron PLCs considered beneficial.

The assignment is focused on supporting a live production environment where there are ongoing automation and production issues. Engineers will be expected to investigate faults, analyse PLC logic, identify root causes and provide clear recommendations and corrective actions to improve equipment reliability and production performance.

This is not primarily a greenfield PLC programming role. The emphasis is on fault finding, diagnostics, troubleshooting, root-cause analysis and production support .

The initial assignment is expected to run for 3–6 months , with engineers working fully onsite as part of a rotating three-shift schedule.

Key Responsibilities

The successful engineers will be responsible for:

• Troubleshooting Siemens PLC-controlled production equipment
• Working extensively with Siemens TIA Portal
• Going online with PLCs to diagnose faults and production issues
• Analysing existing PLC logic, sequences and interlocks
• Investigating recurring production stoppages and equipment downtime
• Identifying whether faults originate from PLC software, electrical systems, sensors, drives, instrumentation, communications or mechanical equipment
• Supporting troubleshooting of automated machinery and production lines
• Identifying bottlenecks, intermittent faults and reliability issues
• Carrying out root-cause analysis
• Recommending corrective actions and technical improvements
• Producing clear action lists outlining issues, priorities and recommended solutions
• Supporting implementation and testing of corrective actions where required
• Working closely with production, maintenance and engineering personnel
• Documenting technical findings and any software modifications made

The key requirement is the ability to systematically diagnose why automated equipment is not performing correctly and determine the most effective solution .

Shift Pattern

The assignment will operate across a three-shift rotation :

• Morning: 06:00–15:00
• Afternoon: 14:00–22:00
• Night: 21:00–06:00

Candidates must be comfortable working across the rotating shift pattern for the duration of the assignment.

Technical Background

Strong hands-on experience with the following is highly desirable:

• Siemens TIA Portal
• Siemens S7 PLCs
• S7-1200 / S7-1500
• PLC diagnostics and online troubleshooting
• Ladder Logic, FBD and/or Structured Text / SCL
• Siemens HMI systems
• WinCC / HMI troubleshooting
• Industrial Ethernet / Profinet
• Drives and motor control
• Sensors, actuators and field devices
• Automated machinery and production lines
• Electrical fault finding
• Machine sequencing and interlocks
• Machine commissioning and start-up
• Production troubleshooting
• Root-cause analysis

Experience with Omron PLC systems , such as Sysmac Studio or CX-Programmer , would be useful but is not the primary requirement .

Experience with other platforms such as Rockwell / Allen-Bradley, Beckhoff or Mitsubishi may also be beneficial.

Candidate Profile

We are primarily interested in mid-level / medior Automation Engineers rather than senior-level consultants.

Ideally, you will have:

• 2+ years of hands-on PLC / automation experience
• Strong practical experience with Siemens TIA Portal
• Previous experience troubleshooting automated production equipment
• Ability to go online with Siemens PLCs and diagnose live production faults
• Ability to read and understand existing PLC code
• Strong f
