Experimental Physicist | Harwell, Oxfordshire | Competitive Salary + Equity
This is a role for a rare kind of physicist: one who is energised, not unsettled, by exploring unanswered questions.
IONECH is a seed-stage energy hardware start-up based at Harwell, Oxfordshire. We're developing the Air Voltaic (AV) Cell — an energy-harvesting device that uses controlled interactions between electrons and oxygen in air to capture subtle natural differences in the environment, converting available exergy into electrical power. At scale, it sits at the base of the energy stack: a platform power source that reduces grid dependence across virtually every electrical use case.
The science is novel, the engineering is hard, and the technology pushes at the boundaries of current understanding. Not every question has an answer yet and that's the point. We're looking for an Experimental Physicist who can make confident progress in that environment: someone who knows when to move, when to ask, and how to extract signal from incomplete information as the full picture gradually emerges.
The work
You'll design, build, and iterate on physical prototypes in our Harwell lab, working directly alongside chemists and engineers on a problem that sits at the intersection of plasma physics, field emission, and energy conversion. This is a ground-floor experimental role. Your hands-on work will directly shape the direction of the technology.
You'll need to be comfortable designing and running experiments without a complete theoretical picture in hand, drawing on your own judgement while actively tapping into the range of specialisms around you; physicists, chemists, and engineers who each hold a piece of the puzzle. The team is collaborative by design; knowing when to seek input is a strength here, not a gap.
