Job Description The salary for this role is £56,596 (inclusive of a Specialist Allowance). This is a permaenent role with UKAEA and the Onsite working is expected for 3 days a week, however, we actively support requests for flexible working. This role can be based in 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 Plasma Code Developer, you will be responsible for developing and maintaining plasma core and edge modelling codes, and for ensuring that UKAEA’s plasma modelling capability incorporates state-of-the-art physics models and features needed to reliably model fusion experiments and concept devices such as MAST-U, JET, STEP, and ITER. Code development will be predominantly focused on the integrated transport modelling suite JINTRAC, including the core transport code JETTO, a multi-fluid code to describe the edge plasma (e.g. EDGE2D or SOLPS), and a kinetic Monte Carlo code (e.g. EIRENE) to describe the neutral particle source. Additional Responsibilities: Responsible for the development of core and/or edge codes within the integrated modelling suite JINTRAC. Local expert in plasma core, multi-fluid edge plasma code, and/or kinetic Monte Carlo neutrals codes. Maintain and document local installations of core (JETTO) and/or edge (EDGE2D-EIRENE) modelling codes. Implement new code features and coupled physics models via a close collaboration with other developers at UKAEA and external laboratories. Support JINTRAC users at UKAEA and external laboratories. Optimise code algorithms for modern computers (HPC). Ensure high quality standards throughout the software development process, maintaining and improving tests and release procedures. Maintain and develop the JAMS GUI and its interface to UKAEA, EURO fusion, and ITER data systems. Demonstrate and disseminate new core and edge JINTRAC algorithms and features to UKAEA plasma modellers and external JINTRAC users. Exploit tools for coupled core-edge simulations to study plasmas on existing or concept fusion devices, such as MAST-U, JET, STEP, and ITER. • Post-holder will be encouraged to disseminate work in publications and at conferences.
