Job description

Company Description By 2050, the planet could be using twice as much electricity compared to today. Are you interested in contributing and helping to shape the future of the world’s energy? If so, read on. Fusion, the process that powers the Sun and Stars, is one of the most promising options for generating the cleaner, carbon-free energy that our world badly needs. UKAEA leads the way in realizing fusion energy, partnering with industry and research for ground breaking advancements. Our goal is to bring fusion electricity to the grid, supported by tomorrow's power stations. In pursuit of our mission, UKAEA embraces core values: Innovative, Committed, Trusted, and Collaborative. As an employee of UKAEA you will benefit from: Outstanding defined benefit pension scheme, details of which can be found at the end of this advert. Corporate bonus scheme up to 7 % and a Relocation allowance (if eligible). Flexible working options including family friendly policies and the right to request flexible working from the start of your employment. Employee Assistance Programme and trained Mental Health First Aiders, Generous annual leave allowance starting with 25 days, plus 3 days Christmas closure and 2.5 privilege days, in addition to UK bank holidays Wide range of career development opportunities A vibrant culture committed to equality and being fully inclusive What to expect in our recruitment process: For a step-by-step overview of how we hire from application to offer please see our Recruitment Process page: careers.ukaea.uk/join-us/recruitment-process 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. Qualifications A demonstrably strong scientific and technical aptitude, and a growth mind-set for acquiring any new specific knowledge or experience needed to deliver the role. PhD level research experience in plasma physics or in a related discipline and post-doctoral experience in plasma modelling Proven ability to conduct independent research. Demonstrable high-quality outputs in areas very relevant to the role, i.e. track record of publications in one or more of: Core turbulent transport models based on gyrokinetics and/or reduced quasilinear models Heat, particle and momentum sources Transport analysis and integrated modelling of tokamak plasma scenarios Ability to interact with physicists and understand their requirements. Good oral and written communication skills. The post-holder must be a good team-player with an outward facing work-ethos as they will work closely with scientists from around the world.
