Job Description The salary for this role is £57,117 (inclusive of a Specialist Allowance) [. Onsite working is expected for 3 days each week, however, we actively support requests for flexible working. This role can be based at any of the following sites: Culham, Oxfordshire. This role requires employees to complete an online Baseline Personnel Security Standard (BPSS), including The Disclosure & Barring Service (DBS) checks for criminal convictions and possibly a search of open source data. The Role Are you looking for an exciting opportunity to make a difference? Join our team and contribute to the future of fusion energy. As Senior Core Transport and Turbulence Modeller, you will play a pivotal role in leading, proposing, and conducting turbulence and transport analysis using advanced transport codes and integrated modelling frameworks like JINTRAC and TRANSP, while exploiting state-of-the-art core turbulence and gyrokinetic codes. The postholder will carry out such analyses for a range of existing and future tokamaks, including MAST-U and the conceptual high-β spherical tokamak power plant, STEP. Additionally, you will direct, propose, and execute experiments on MAST-U, aiming to validate and guide the development of reduced transport models, ultimately enhancing confidence in predictive simulations of core transport. Key Responsibilities: Provide scientific leadership and guidance in developing and validating turbulence models to produce predictive simulations of the core plasma transport in support of the UK’s STEP programme. Maintain and guide the development of Prokinetics, the Python library used for gyrokinetic code analysis. Direct, propose and execute experiments on MAST-U, especially in the area of the role. Act as the scientific point of contact for core plasma modelling on MAST-U. Nurture and grow existing collaborations, and seek new opportunities for national and international collaborations. Provide guidance and expertise, directing the future of development of transport and turbulence analysis at UKAEA. Report results at science and other regular progress meetings. Disseminate results through presentations, conferences, and peer reviewed journal papers. Guide. and mentor Early Career researchers in areas relating to turbulence and transport modelling.
