DESCRIPTION & REQUIREMENTS
On behalf of UK Fusion Energy we are looking for a Portfolio Manager Inside IR35 for a 12 months contract based Hybrid 3 days a week in Retford
Fusion energy offers the potential for significant quantities of low-carbon, inherently safe, abundantly fuelled, baseload energy, supporting sustainable climate action and energy independence. While the technical challenge remains high, confidence is increasing, and the rewards of realising fusion are almost incalculable. Anticipated to come online for commercial purposes in the middle of this century, fusion offers a viable means to sustainable net zero in the UK and globally, as well as to increased energy security. The UK is currently a world leader in fusion research and development and in the drive to realise commercially viable energy from fusion, a sector with an estimated value of £tns per year.
STEP (Spherical Tokamak for Energy Production) is the UK’s flagship national programme to deliver a prototype fusion energy plant, targeting 2040, and a path to commercial viability of fusion. STEP is deliberately bold and ambitious and seeks people who want to be part of a world-changing endeavour and who have credible and relevant experiencing in delivery.
ILIOS consortium was selected in early 2026 as Construction Parter on STEP. Ilios is a 50/50 joint venture between Kier and Nuvia, supported by consortium partners AECOM, AL_A, and Turner & Townsend, and support from strategic suppliers.
