Electrical Maintenance Engineer

⚡ Electrical Maintenance Engineer
 Permanent | Full-Time | 40 hours per week | Rotating Shifts

 
Location: Chester 

Salary: £24.71 per hour (including 25% shift uplift for all hours worked)

Shift Pattern:

• Monday – Friday: 06:00–14:00 / 14:00–22:00 (rotating weekly)

• Participation in planned shutdowns and commissioning periods required, including 27th–31st December 2026

🏭 About the Role 

We are seeking a skilled Electrical Maintenance Engineer to support the safe, compliant, and reliable operation of heavy industrial production assets within a lead (Pb) manufacturing environment.

 
You will play a key role in maintaining and improving equipment across rolling mills, extrusion lines, CNC machining cells, and associated hydraulic and extraction systems.

 
This is a hands-on, shift-based engineering role combining reactive fault finding, preventative maintenance, and continuous improvement activity within a safety-critical environment.

 
 🔧 Key Responsibilities 

• Diagnose and resolve electrical and control system faults, including complex and intermittent issues, to minimise production downtime

• Fault-find and maintain Mitsubishi and Siemens PLC-controlled systems (I/O, sequencing, alarms, communications)

• Support and troubleshoot VFD and servo drive systems, including parameter adjustments and trip analysis

• Maintain and fault-find electro-hydraulic systems, identifying issues such as pressure loss, overheating, contamination, drift, and valve failures

• Ensure strict compliance with LOTO, isolation procedures, guarding, and functional safety testing

• Support and maintain LEV/extraction systems, ensuring interlocks, sensors, and alarms function correctly and reliably

• Carry out root cause analysis (RCA) and implement continuous improvement (CI) initiatives to reduce repeat failures and scrap

• Support commissioning activities, including I/O checks, interlock validation, and controlled system testing

• Maintain accurate technical documentation, including PLC backups, parameter records, and electrical/hydraulic drawings

• Provide clear and structured shift handovers, ensuring continuity across teams

 

 
 ⚙️ Equipment You’ll Work On 

• Rolling mills (high-torque drives, tension control, safety interlocks)

• Extrusion lines (multi-zone temperature control, hydraulics, LEV permissives)

• CNC machining cells (safety circuits, machine interfaces, coolant/lubrication systems)

• Hydraulic presses, guillotines, and power packs

• LEV and extraction systems with airflow and differential pressure monitoring

• Industrial heating systems including thermocouples, controllers, SSRs and contactors

 

 
 🧠 What We’re Looking For 

• Strong industrial electrical maintenance experience in a manufacturing environment

• Proven ability to troubleshoot PLC-controlled systems

• Experience with Siemens (TIA Portal) and/or Mitsubishi (GX Works) desirable

• Ability to read and interpret electrical schematics confidently

• Good understanding of VFD/servo drive systems and diagnostics

• Working knowledge of hydraulic systems and fault-finding principles

• 
  Strong problem-solving skills under pressure with a structured approach

• Excellent communication and shift handover discipline

 

 
 🎓 Qualifications (Desirable) 

• HNC/HND in Electrical Engineering, Controls, Mechatronics (or equivalent experience)

• PLC, servo or automation training (Siemens / Mitsubishi preferred)

• Electrical safety training and/or hydraulic system experience

 🌍 Working Environment 
This is a heavy industrial environment involving exposure to heat, noise, and lead particulate materials. Strict PPE, hygiene controls, and safety procedures are in place at all times.

 
The role is fully hands-on and shop-floor based, with occasional support for contractors and commissioning activities.

 
 🎁 What’s in it for You 

• Competitive hourly rate with shift allowance included

• Overtime opportunities available

• Company pension scheme

• Training and development (PLC, electrical, mechanical upskilling)

• Full PPE provided, including respiratory protection for lead environments

• Opportunity to work on complex, heavy-industry systems with genuine technical depth
