Job Description

Location: Aldermaston, West Berkshire. We are located between Reading and Basingstoke, with onsite parking.

The role will support flexible working with an expectation that the candidate will spend some time working at AWE main site each week and that the place of work is driven by the needs of the programme.

The Role:

AWE has an exciting Theoretical Scientist role to support our deterrence programmes as we expand our mission space. This role will develop the right candidate with their scientific career, offering exciting opportunities to develop our radiation detection and uncertainty quantification capabilities.

The Radiation Science Group is tasked with supporting the hardness and vulnerability aspects of our deterrence mission space, identifying, assessing, and understanding threats to the deterrent and looking to the future and the next generation of systems.

The group uses a model-based engineering approach to support core missions, with the models being underpinned by science lead activities, i.e., developing and validating new models and codes, verifying them through experiments and assessing the certainty associated with the methods. The role therefore encompass skills from experimental, theoretical and computation branches of physics and is a great opportunity for the right candidate with a passion for physics.

This role would support the whole group by independently assessing the experimental and modelling activities undertaken and seeking to increase our confidence in our overarching assessments.

The expectation is the right candidate would be trained and grow into this role, developing knowledge in statistical analysis and coding/modelling languages (e.g. Python, C, C++, Matlab, MCNP, Geant4).

Broad understanding of various physics concepts including material properties, radiation field analysis, electronic systems, electromagnetic phenomena and a strong mathematics or statistics background preferred but not essential.

Whilst not to be considered a check list, candidates should be able to demonstrate some of the following:

  • Essential - Degree level knowledge in Physics (2:1 or above), Mathematics or statistics

  • Desirable - Post-graduate qualifications connected with working on radiation detection and/or statistical methods.

  • Strong communication skills, verbal and written, excellent team working ability, proactive, and highly organised.

  • Willing to travel and work at other UK and overseas sites as required.

Key Responsibilities

  • Owning the development of the areas and expanding the capabilities in accordance with programme needs.

  • Using appropriate software and data capture tools to record data and suitable analyses.

  • Providing suggestions for improvements for team workflows with a view to being able to expand this to all workflows within the group.

  • Optimising experimental and trial designs and supporting (potentially leading) the delivery teams.

  • Working safely, securely, and cleanly to the appropriate quality standards.

  • Analysing scientific data to assess confidence and uncertainties in the data and the methods used to obtain the data.
