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).
Who are we:
We’re a forward-looking, progressive energy systems business building a flagship hydrogen production, compression, storage and fuelling facility. You’ll collaborate with Operations, SHEQ, Capital Delivery, Strategy & Business Development and OEM partners to deliver a plant that is safe, compliant, reliable and optimised—setting standards others will follow.
