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
