ITM is at the forefront of the green hydrogen industry, designing and manufacturing cutting‑edge PEM electrolysers that are instrumental in global decarbonisation efforts. With over two decades of scientific expertise, we’ve established ourselves as industry leaders in clean energy technology.

As pioneers in green hydrogen technology, ITM is offering the most advanced PEM electrolyser technology in the world. Founded in 2000, ITM Power PLC was one of the first companies of its kind to be listed on the AIM market of the London Stock Exchange. Headquartered in the UK, our state‑of‑the‑art manufacturing facility is the world’s first largest PEM Gigafactory in commercial operation, and home to our R&D and manufacturing.

ITM Power Germany is our hub in the heart of the EU. This facility not only houses regional functions including business development and engineering, but also our aftersales services with the ability to quickly deploy stacks.

Our PEM electrolysers are deployed in some of the world's largest green hydrogen projects. We continue to push the boundaries of technology, enhancing cost‑effectiveness and sustainability.

ITM is in the midst of a transformative phase, focusing on streamlined delivery and operational excellence. We're seeking talented individuals who share our passion for clean energy and our drive to make a tangible impact on the world's transition to net‑zero.

You will be working with an inspiring bunch of people, encouraging each other to be the best we can. We’ve come a long way, join us in the next step of our incredible journey!

Working within our stack design and verification team, reporting to the Head of Stack Development you will support the design, development, prototyping, and validation of next‑generation full‑scale PEM electrolyser stacks and clamping skid frame systems. The successful candidate will play a key role in developing and executing experimental test programs, validating mechanical performance, and supporting the transition from prototype to industrial‑scale deployment.

• Develop and execute verification and validation (V&V) plans for full‑scale PEM electrolyser stacks and clamping skid frame assemblies.
• Design and conduct mechanical, hydraulic and thermal test programs.
• Define test procedures, acceptance criteria, instrumentation requirements, and data acquisition strategies.
• Perform stack pressure, leak, load, compression, vibration, and endurance testing.
• Support FAT/SAT and prototype commissioning activities.

• Collaborate with mechanical, electrical, controls, and electrochemistry teams during stack and skid frame prototyping.
• Assist in the assembly, integration, and troubleshooting of prototype electrolyser systems.
• Evaluate structural integrity, clamping force distribution, sealing performance, and operational reliability.
• Support design iterations based on test outcomes and root‑cause investigations.

• Analyse test data and generate detailed technical reports with clear conclusions and recommendations.
• Develop performance validation metrics and reliability benchmarks.
• Use statistical and engineering analysis methods to identify trends, anomalies, and failure mechanisms.
• Present findings to internal engineering teams and project stakeholders.

• Specify and support procurement of test equipment, sensors, DAQ systems, and instrumentation.
• Develop safe operating procedures for hydrogen and high‑pressure testing environments.
• Support calibration, maintenance, and continuous improvement of R&D test facilities.

• Work closely with design engineers, manufacturing, suppliers, and project teams to ensure robust product verification.
• Contribute to DFMEA, risk assessments, and verification reviews.
• Support scaling activities from prototype through pilot and commercial deployment.

• Contribute to continuous…
