We have a fantastic opportunity for a highly organised and detail-driven ICA Engineering professional to join our close-knit, dynamic team at N-Gen. You’ll act as the ICA technical authority on a new hydrogen production, compression, storage and fuelling facility, shaping automation philosophies and safe systems of work across instrumentation, PLC/SCADA, ESD and F&G, and LV control circuits to deliver safe, reliable and efficient operations. If powering future ready hydrogen operations excites you, we’d love to hear from you today.
Key responsibilities:
* Specify and govern instrumentation for hydrogen service, including pressure, flow, gas detection and metering.
* Lead control system design reviews for PLC, RTU, SCADA, HMI and industrial network architectures.
* Integrate functional safety, supporting SIS and F&G design, trip logic and proof‑testing regimes.
* Deliver hazardous area compliance for ICA equipment to IEC/BS EN 60079 and manage Ex inspection regimes.
* Ensure LV control systems, panels and ICA circuits meet BS 7671 and EAWR requirements.
* Apply DSEAR principles to minimise ignition risks and ensure control system integrity during gas releases.
* Develop RCM‑based maintenance strategies for instruments, control panels, Ex apparatus and automation systems.
* Build and manage ICA asset hierarchies, criticalities, PM routines, condition monitoring and spares.
* Drive reliability through RCA, trend analysis, nuisance trip reduction and automation system improvements.
* Manage ICA authorisations and audit competency under agreed Authorising Engineer frameworks.
* Enforce cybersecurity standards for PLC/SCADA — access control, patching, configuration and segmentation.
* Oversee commissioning: loop checks, FAT/SAT, I/O testing, logic validation and Ex inspections.
* Produce and review ICA designs, including drawings, loop diagrams, narratives, cause‑and‑effect and system architecture.
* Control configuration changes to PLC logic, SCADA graphics, setpoints and firmware under formal MOC.
* Support ICA planning, capex/opex forecasting and long‑term investment decisions.
Knowledge & technical know-how:
* EAWR 1989 and HSG85 safe working practices; BS 7671 (18th Edition) LV control circuits and verification/testing.
* DSEAR and IEC/BS EN 60079 for Ex equipment/cabling, installation and inspection; ISO/TR 15916 hydrogen hazards.
* PLC/SCADA/RTU architectures, industrial networks and cybersecurity principles; COMAH safety instrumentation and alarm management.
* Interfaces with ISO 22734 (electrolysers) and ISO 19880-1 (fuelling) systems; functional safety IEC 61511/IEC 61508.
Skills and experience required:
* Ex installation/inspection to IEC/BS EN 60079; develop maintenance strategies and reliability methodologies (e.g., RCM).
* Lead commissioning (FAT/SAT, loop checks, logic validation) and communicate effectively across Operations, Maintenance, Capital Delivery and SHEQ.
* SIL awareness and functional safety lifecycle; ICS cybersecurity capability.
* Minimum of 3 years in ICA within process, energy, utilities, hydrogen, petrochemical or heavy industry.
* Involvement with COMAH safety reports and safety-critical instrumentation.
Qualifications:
* Degree (BEng/BSc) in Instrumentation, Electrical/Electronic, or Control & Automation Engineering; BS 7671 (18th Edition).
* Desirable: Functional safety (IEC 61511), PLC vendor certifications, CompEx Ex01–Ex04 (or equivalent), ISA/IEC 62443 cybersecurity, Authorised Person (LV/Control).
You must have a legal right to work in the UK, be available to work in Leeds, have hands‑on experience delivering instrumentation, control and automation (ICA) or electrical engineering on hazardous‑area or process‑industry sites (e.g., hydrogen, gas, chemicals, energy, oil & gas) and have previously worked with PLC/SCADA systems, instrumentation, or control system reliability and can you demonstrate how you’ve improved plant performance or resolved complex automation faults.
