About LUX

LUX is an exciting start-up daring to disrupt existing industry norms and take the lead in revolutionising the approach to Liquid Hydrogen. We are based in Oxfordshire, the centre of Cryogenics R&D in the UK, ideally located for developing our unique Clean ‘Green’ liquid Hydrogen technology. LUX is currently developing the technology to ultimately supply our customers with Clean liquid Hydrogen on-site-on-demand.

We are scaling at pace, raising significant grant funding and private investment. LUX embraces new technologies, processes & methods at the core of our engineering approach. We have a welcome approach to taking risks and believe that learning from failure and iterative testing achieves the best results.

Our ethos is one of informed ideation, focussed risk-taking and passion for change. LUX is seeking candidates who are enthused by the idea of defining new possibilities in engineering Hydrogen liquefaction systems. We are offering candidates an opportunity to work on the cutting edge of liquid Hydrogen innovations, and be fairly rewarded for their time, effort and skills. We are growing fast and we make decisions quickly.

If you feel this could be the journey for you, we would like to hear from you.
