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.
Benefits
- 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
