Overview
We have a fantastic opportunity for a detail driven– Senior Process Engineer (Hydrogen – Asset Integrity & Compliance) to join our close‑knit, dynamic team and act as technical authority for a new hydrogen facility. You’ll champion DSEAR, ATEX/UKEX, IEC/BS EN 60079, PSSR and COMAH compliance, lead HAZID/HAZOP/LOPA, and drive performance through robust mass & energy balances, relief sizing and operating envelope optimisation. If shaping safe, reliable, future ready hydrogen operations excites you, we’d love to hear from you today.
Key responsibilities
* Lead process design for hydrogen production, purification, storage, compression and dispensing systems.
* Develop asset strategies, criticality assessments and long‑term lifecycle plans.
* Improve plant performance through operating envelope optimisation and reliability tracking.
* Produce operating manuals, SOPs, alarm/trip philosophies and commissioning documentation.
* Manage technical changes under MOC, ensuring risk evaluation and regulatory compliance.
* Build process models and simulations for design, troubleshooting and optimisation.
* Review supplier packages, datasheets and engineering deliverables for design assurance.
* Support construction and ensure alignment with hazardous‑area and pressure‑equipment requirements.
* Participate in commissioning, validate systems and capture lessons learned.
* Provide operational troubleshooting, root‑cause investigations and optimisation support.
* Define maintenance inputs such as SIL proof tests, inspection intervals and spares.
* Prepare capex/opex budgets, investment plans and maintain compliance with hydrogen‑specific standards
Knowledge & technical know‑how
* Hydrogen properties and hazards (per ISO/TR 15916); strong fundamentals in heat/mass transfer, thermodynamics, separations, reaction engineering and fluid dynamics.
* Working knowledge of COMAH, DSEAR, and hydrogen standards (ISO 22734 for electrolysers; ISO 19880‑1 for fuelling).
* Understanding of advanced process control and digitalisation (APC, real‑time optimisation, digital twins).
Skills and Experience
* Expert delivery and review of PFDs, P&IDs, datasheets and simulations; strong process‑safety capability including HAZOP leadership and hazard analysis.
* Clear communicator with excellent cross‑functional coordination (design, operations, maintenance, SHEQ) and strong technical decision‑making with MOC governance.
* Proficiency with Aspen HYSYS, UniSim or gPROMS; experience in digital commissioning, data analytics and performance monitoring; mentoring of junior engineers.
* Minimum of 5 years in hydrogen, chemical, refining, energy, gas processing or similar high‑hazard industries.
* Proven delivery from FEED through detailed design, construction and commissioning.
* Demonstrable strong track record in operations support and reliability improvement.
* Exposure to COMAH safety reports, SIL determination or hydrogen‑specific systems (electrolyser/storage/compression/dispensing).
Qualifications
* BEng/MEng in Chemical/Process Engineering (or related).
* Chartered Engineer (CEng) or working towards (IChemE preferred).
You must have a legal right to work in the UK, be available to work in Leeds, have hands‑on process engineering experience in hydrogen, gas, chemical, energy or other process‑industry environment and have delivered process design or process safety activities such as HAZOP/HAZID, DSEAR zoning, relief system design or process modelling.
