Let us introduce the role AWE is currently recruiting for a Theoretical Scientist to join the Environments and Transport (EAT) Team which sits within our Radiation Science Group (RSG). This role is ideally suited to a Physicist with interest in developing physics codes and modelling the interaction of radiation (photons, electrons, and neutrons) with matter. Working within the Radiation Science Group the successful candidate will be part of a team applying and developing radiation effects tools to solve the interaction of nuclear radiation environments with complex geometries. This role provides excellent development opportunities and the chance to collaborate with partners in the UK, and overseas. You will gain an understanding of Monte Carlo and deterministic radiation transport techniques, work with developers to ensure these are robustly implemented, and develop our future physics codes using modern software practices. You will apply these using AWE's High-Performance Computing (HPC) platforms to our core product and to our experimental programmes, utilizing meshing tools to support Finite Element Analysis (FEA). Who are we looking for? We do need you to have the following: A strong degree in Physics or a related discipline, with a focus on modelling or code development.Although not essential, a Ph D or relevant post-graduate experience would be beneficial for this role.A willingness to travel overseas is essential to participate in modelling workshops and peer reviews. Whilst not to be considered a tick list, we'd like you to have experience in some of the following:An understanding of how radiation interacts with matter.Familiarity with radiation transport codes, such as MCNP, Open MC, or Geant4.Developing physics codes and models.Programming languages such as Python or C++.Linux and High-Performance Computing (HPC). You'll need to have the ability to work calmly and constructively in a priority changing environment and be able to manage your own workload. You will also have initiative, enthusiasm, a flexible approach, and ability to work to tight deadlines. Some reasons we think you'll love it here: AWE has wide range of benefits to suit you.
