Senior Process Commissioning Engineer Clean Power Hydrogen Group Ltd is a vibrant alternative energy technology company based in Doncaster. Our technology platforms have caught the attention of many organisations both here in the UK and overseas. As a result, we are looking to expand our engineering design team to development and scale-up our Membrane-Free Electrolysers™ This role is a fantastic opportunity to work in an engineering environment in the hydrogen production sector. We offer a collaborative and friendly work environment that finds cutting edge solutions across a broad range of engineering disciplines. This role also gives you the chance to be part of a business who promotes development and recognises talent and is your opportunity to join a rapidly growing business. About CPH2: Clean Power Hydrogen Group Ltd (CPH2) is a leading developer of Membrane-Free Electrolysers™ designed to produce green hydrogen and pure oxygen in a simple, safe, sustainable manner and at any scale. Dr. Nigel Williamson and Joe Scott established CPH2 (Ireland) in December 2012 with the ambition to help clean up the environment for our children and future generations. Entering the green technology sector, a high growth, and profitable market, they developed a Membrane-Free Electrolyser™ to produce hydrogen faster, more reliably, and more cost-effectively than PEM technology, which has barriers to adoption, including cost, reliability, and scalability. About the job: As a Senior Process Commissioning Engineer, you will report to the Process Engineering Manager and collaborate on projects system build to FAT/SAT sign-off. You will work closely with the Mechanical, Process, Electrical, and Procurement teams as well as potential external vendors and contractors. The successful candidate will play a critical role in the commissioning and start-up of electrolyser systems, ensuring they meet design, safety, and performance requirements. The ideal candidate is expected to eventually lead the commissioning function within the business. Responsibilities will include: Review and interpret process flow diagrams (PFDs), piping and instrumentation diagrams (P&IDs), and equipment datasheets. Develop detailed commissioning and start-up procedures for process systems. Coordinate with project stakeholders to ensure readiness for process commissioning activities. Perform pre-commissioning activities such as line flushing, pressure testing, and equipment integrity checks. Verify process equipment performance, including pumps, heat exchangers, drying systems etc. Conduct process simulations and functional testing to ensure alignment with design specifications. Monitor and optimise chemical process parameters during commissioning to achieve desired operational efficiency. Identify, troubleshoot, and resolve process deviations or inefficiencies. Work closely with control and instrumentation teams to fine-tune control loops and automation systems. Ensure commissioning activities adhere to industry standards, safety protocols, and environmental regulations. Particularly pertaining to Safety PLCs and ATEX/IECEx compliance. Participate in hazard reviews (e.g., HAZOP, LOPA) and implement recommendations during commissioning. Develop and document operational risk assessments and mitigation plans.
