The Ministry of Justice

The Ministry of Justice is a major government department, at the heart of the justice system. We work to protect and advance the principles of justice. Our vision is to deliver a world-class justice system that works for everyone in society. We are passionate about improving justice outcomes through innovative research, data and analysis.

The Data Science Hub

We are a multi-disciplinary team of around 70 staff that sits at the heart of the Ministry of Justice providing data science support across a diverse and exciting agenda. We work in a dynamic and fast-paced context and our skills are in heavy demand across the Ministry of Justice. Our collaborations beyond government are seen as ground-breaking.

We create a culture in which people are empowered with the data and information to make excellent decisions using cutting edge tools, techniques and collaboration and putting evidence at the heart of the justice system.

We have a track record of delivering digital services to front line staff using wide ranging data science techniques, including the award-winning safety diagnostic tool, which helps our staff tackle violence in prisons. We regularly deliver insights that directly influences corporate, operational and policy decisions. Our projects span the data science spectrum including machine learning, natural language processing, automation, advanced visualisation and optimisation.

What you’ll do

You will work as part of multi-disciplinary teams to deliver data science products and analysis.

The majority of projects will be conducted using Python, R and SQL on our AWS cloud infrastructure (known as the Analytical Platform) to work with data from across the justice system. You will work closely with other data scientists, the Data Engineering Hub (which builds the tools, services and pipelines that make data available on the Analytical Platform) as well as other data, digital, policy and operational colleagues.

Key responsibilities

  • Work with Senior and Lead Data Scientists on shared codebases to deliver data science products and analysis across the criminal justice system (e.g. within prisons, for the Probation Service)
  • Learn and use best practice approaches in project delivery, such as version control and code review
  • Effectively communicate with a variety of stakeholders
  • Keep up to data with the wider data science landscape and emerging technologies
  • Contribute to making the Data Science Hub an inclusive and vibrant place to work

Who you are

We’re interested in people who have:

  • Experience working with data and completing analysis and a keen interest in applying data science techniques
  • Experience in writing code in one or more programming languages, ideally Python, R or SQL
  • An understanding of the importance of version control, quality assurance and producing robust and reproducible analysis
  • The ability to effectively communicate with diverse stakeholders

How to apply

You’ll need to submit an anonymised CV and Statement of Suitability as part of your application. You will not be considered if you do not provide both.

Your CV should be no more than 2 pages long and should show us your work history and previous experience. It should be well structured, succinct and written in clear language. Try to avoid just listing technology keywords; we are interested in how you have used different tools to solve problems.

Your Statement of Suitability should be no more than 750 words and should give us examples of how your skills and experience match those needed for this role. Consider giving an example for each bullet point in the skills requirements ‘Who you are’ section and use work you have completed to demonstrate how you meet each one.

All these requirements are important for the job, however we do not expect candidates to be expert in all of them. Just give as much evidence as you can for each and make sure you cover ‘how’ you demonstrated the requirements and the impact of your work, as well as ‘what’ you did. Again, if you are interested in applying but are not sure you have all the skills listed, please do apply and give us the opportunity to consider you as a candidate.

Selection process

There will be an initial sift of applicants through comparing submitted evidence against the ‘Who you are’ bullets. This usually takes two weeks, depending on the number of applications.

Applicants invited for interview

Those who make it through the initial sift will be invited to a Civil Service Success Profile interview. In the Civil Service we use Success Profiles to help us find the right person for the job. We will be using a mixture of methods to assess your abilities, strengths, experience, technical skills and behaviours. We highly recommend learning about Success Profiles and using the Situation, Task, Action, Result and Reflection (STARR) framework when structuring your answers.

The highest scoring candidates that pass the interview will be offered the roles. The whole process can take a month. Other candidates that pass the interview will be kept on a merit list for 12 months.


At the interview we will be asked to give a five-minute presentation on an analytical or data science project you have delivered. Details of this will be sent to candidates before the interview.


The following behaviours will be tested:

  • Communicating and Influencing – tell us how you work with colleagues to understand their needs and facilitate collaboration
  • Managing a quality service – tell us when and how you have worked with colleagues to set priorities, objectives and timescales under challenging circumstances

In your examples you should include evidence on ‘how’ you demonstrated the requirements and the impact of your work, as well as ‘what’ you did.

Technical – Data science skills

We’ll assess you against these technical skills during the selection process:

  • data science expertise
  • working practices
  • programming and coding skills

Technical – Analytical Competency

For external (non-Civil Service) candidates (and unbadged candidates within the Civil Service), as well as the three civil service behaviours and Data Science skills stated above, you will be assessed on your analytical knowledge, experience and abilities, and the impact of your analytical work. 

For existing Civil Service analysts from all professions, as well as the civil service behaviours and Data Science skills stated above, you will be assessed on two sets of the relevant professional competencies at interview. Please refer to the analytical profession frameworks in the appendix section for more information.

Further Information and Appendix

We welcome applications from candidates based across the UK. Candidates will have the option of being based in the Leeds or London HQ offices (with flexible working arrangements available) or your nearest Justice Collaboration Centre or Justice Satellite Office. These are in Liverpool, Leeds, South Tyneside, Manchester, Bristol, Nottingham, Cardiff, and Brighton, Stafford, Ipswich, Wolverhampton, Sheffield. Alternative locations may be available and will be discussed and agreed on the completion of background checks.

Interviews are likely to take place in January 2023 and will be held via MS Teams. We will keep a merit list for a year for those who successfully pass the interview board but who are not offered a post.  If you require any additional information about the role, please contact: Data & Analysis Recruitment Team: .
