Electrical Engineer

1111 recruitment Ltd; Chester; On-site; GBP 50,000 - 61,000; Full time

Job summary

1111 recruitment Ltd is seeking an Electrical Maintenance Engineer to support lead metal production assets across rolling, extrusion and CNC areas. You will balance reactive breakdown support with preventive reliability upgrades, working hands-on with electrical power, PLCs, drives, and hydraulics in a heavy‑industry environment with LEV interlocking.

The role involves a rotating three‑shift pattern (06:00–14:00, 14:00–22:00, 22:00–06:00) and participation in planned shutdowns.

Qualifications

• Proven electrical basics for heavy industry and power/control circuits.
• Experience with PLCs: Mitsubishi GX Works and Siemens TIA Portal preferred.
• Ability to read and update electrical schematics and wiring diagrams.
• Experience with VFD/servo drives and basic control loops.
• Exposure to hydraulics and lubrication/press systems is a plus.
• Strong manufacturing mindset with problem solving under pressure.

Responsibilities

• Diagnose and resolve electrical/control faults safely to restore production.
• Troubleshoot Mitsubishi and Siemens PLC‑controlled machinery: I/O, sequences, alarms, and comms.
• Support fault‑finding on drives (VFD/servo) including torque and accel/decel analysis.
• Assist electro‑hydraulic systems: pressure, flow, and PLC‑related symptoms.
• Maintain compliance: LOTO, isolation, guarding and interlocks tests.
• Support LEV/extraction compliance, sensor health, and alarm responses.
• Deliver RCA/CI actions and implement preventive measures to reduce repeats.
• Carry out modifications/commissioning with thorough I/O checks and validations.

Job description

Electrical Maintenance Engineer

Shifts: 06:00–14:00 / 14:00–22:00 /22:00-06:00

£55k inc shift rate.

Role purpose

Support safe, compliant and reliable operation of lead (Pb) component and lead sheet production assets across rolling, extrusion and CNC-machining areas. The role balances reactive breakdown support with preventive reliability improvement and small–medium CAPEX/CI upgrades. Expect hands‑on work across electrical power, PLC/controls (Mitsubishi + Siemens), drives, instrumentation, and electro‑hydraulic systems in a heavy‑industry environment with strict lead exposure controls and LEV (fume extraction) interlocking.

Shift pattern

Predominantly rotating three-shift pattern: mornings/afternoons/nights

Participation in planned shutdowns and commissioning windows as required inc Dec 27 - 31

Typical equipment footprint

Lead melting/heating zones (where applicable): heaters, thermocouples, controllers, SSRs/contactors.

Rolling mills: high‑torque drives, tension/position feedback, roll-gap/force control, interlocks.

Extrusion lines: multi‑zone temperature control, drives, hydraulics, safety and LEV permissives.

CNC machining cells: safety circuits, machine‑ready interfaces, peripherals (coolant/lube/chip handling).

Hydraulic presses/guillotines/forming: power packs, proportional valves, cylinders, accumulators, filtration.

LEV/extraction and monitoring: airflow/differential pressure sensing, alarms, shutdown permissives.

Key responsibilities

• Diagnose and resolve electrical/control faults safely (including intermittent faults) to restore production.
• Troubleshoot Mitsubishi and Siemens PLC‑controlled machinery: I/O, sequences, alarms and comms.
• Support and fault‑find drives (VFD/servo): trip analysis, torque/current limits, accel/decel, PID loops etc
• Support electro‑hydraulic systems: pressure/flow loss, drift, overheating, cavitation, contamination, internal leakage, and their PLC symptoms (timeouts/chatter/analog instability).
• Maintain compliance: LOTO/isolation (electrical + hydraulic + thermal), guarding/interlocks, and functional proving tests.
• Support LEV/extraction compliance: ensure correct interlocks, sensor health, and alarm response; use trends to improve reliability.
• Deliver RCA/CI, implement preventive actions to reduce repeat stops and scrap.
• Commission modifications/upgrades; complete I/O checks, interlock proving, controlled trials and verification.
• Maintain documentation/change control: PLC backups/versioning, parameter logs, and up‑to‑date as‑built electrical/hydraulic drawings.
• Work effectively across shifts with strong handover: current status, actions taken, what changed, risks, and next steps.

Required skills

• Industrial electrical fundamentals: 3‑phase motors, protection, earthing, control circuits, panels/MCCBs.
• Proven troubleshooting on PLC‑controlled machines; Mitsubishi GX Works and Siemens TIA Portal experience preferred.
• Ability to read and update electrical schematics.
• Drives competence: understands diagnostics and parameters; can capture evidence and implement controlled changes.
• Hydraulics exposure: pressure/flow reasoning, contamination effects, safe depressurisation/accumulator awareness.
• Manufacturing mindset: structured problem solving under pressure; good communication with production/maintenance.

Qualifications / desirable

• HNC/HND in Electrical/Controls/Mechatronics (or equivalent experience).
• Desirable: PLC & Servo Drive experience (Mitsubishi/Siemens), electrical safety training, hydraulics experience.

Working conditions

Heavy manufacturing environment with heat, noise and lead particulate; strict PPE and hygiene/contamination controls.

Hands‑on shop‑floor support with occasional contractor supervision and commissioning
