These roles will be based in the Data Science Hub. The Data Science Hub is a multi-disciplinary team of 40+ people from a range of professions and backgrounds. We have delivered high impact data products that have been productionised and widely used across the business and provided insights that directly influences corporate, operational and policy decisions. These span the data science spectrum including automation, advanced visualisation, machine learning, natural language processing and optimisation. We are now collaborating withMoJ Digital with the aim of getting live data pipelines as new services are being built, with the plan to deliver data science products through these services.

The majority of projects will use either Python, R, and/or Spark in our AWSAnalytical Platform, using Github for version control and effective collaboration.

You will work as part of a multi-disciplinary product team delivering trusted data science through the new MOJ Digital & Technology Probation products and services. Your work will aim to improve critical decisions made in and service user outcomes achieved by the UK Probation system.

Data Scientists in our small, agile teams deliver robust insights and innovative solutions that are directly deployed to end-users (operational, policy, corporate). Our agile teams are empowered to decide on how to validate MVPs, build proof-of-concept solutions and set their own milestones and timelines given key stakeholder needs.

You will be responsible for developing and applying a wide-ranging toolkit (data visualisation, predictive and explanatory modelling, machine learning, NLP) to solve business problems, including delivering working apps/products to our policy and operational customers. In addition to applying familiar tools, you will have the opportunity and support to learn a range of cutting-edge tools and deployment frameworks.

As our seniorData Scientist in the Data Science Products team, you will work closely with analysts across the Data & Analytical Services Directorate. You will provide expertise and support on the development of Data Science Projects across the Data & Analytical Services Directorate. You will work closely with Analysts, Policy, operational and wider professionals to identify, deliver and frequently productionise high quality Data Science Products.

You will be a technical expert on a range of techniques by ensuring you are up to date with latest developments in data science across government and beyond including developing strong relationships with key external stakeholders. You will look for opportunities to bring latest research to bear on MoJ problems whether through strategic partnerships or developing those skills in-house. You will ensure that the business feels fully supported to utilise cutting edge techniques and continue to establish best practice and ethical ways of working around these cutting-edge techniques.

We’re interested in people who have:

  • experience in writing clear and concise code, and working with scripting/programming and database programming languages, specifically Python, R and SQL, to automate and present data frameworks;
  • a track record of using quality assurance and automated testing in analytical work, including producing robust and reproducible analysis using modern version control software;
  • strategic thinking and problem solving aligned with organisational goals, with ability to identify preventative measures and opportunities for data innovation and promoting adoption and learning of new tools and techniques;
  • experience of working with diverse stakeholder groups to deliver data science products and explaining data concepts and practices to technical and non-technical stakeholders;
  • Building best practices such as version control, unit testing, code review, and well documented applications.

The candidates are not expected to have experience with the full range of technologies of the Analytical Platform, but we are looking for candidates who are excited about the opportunity to quickly learn new things with the support of our technical experts.

Specific responsibilities will be tailored to reflect your strengths and development needs.

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.

Those who make it through the initial sift will be invited to a Civil Service Success Profile interview. In the Civil Service we useSuccess 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.

Interviews are likely to take place in October 2021.


At the interview we will be asked to give a five-minute presentation on a 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
  • Managing a Quality Service
  • Changing and Improving

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 – skills

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

  • performance analyst expertise and technical leadership
  • working practices
  • programming and coding skills

Technical – Analytical Competency

We’ll assess you against the analytical competencies depending on these two options:

  1. Existing analysts from all professions (GORS/GSG/GSR/GES) will be asked for evidence of how you meet the requirements of the relevant professional competency framework, with particular focus on communicating analysis and achieving impact.
  2. Non-analysts who would like to join GORS or GSG will be assessed on achieving impact with analysis (GORS Achieving impact with analysis / GSG Presenting and disseminating data effectively). GSG candidates will additionally need to go through a badging board at a later stage.

Please refer to the analytical profession frameworks in the appendix section for more information.
