Lead Data Scientist – Grade 7Data & Analysis, Ministry of Justice


We have an exciting permanent opportunity in our data linking team, working with our award winning team behind the Splink software. This is based within the Data Science Hub within the MoJ Data & Analytical Services Directorate at Grade 7 and working on the cross government ‘Better Outcomes through Linked Data’ Programme (BOLD). 

The salary will be negotiable within the Grade 7 pay range depending on your skills and expertise as assessed in the selection process.

Roles are open to: 

  1. Existing analysts from all professions (GORS/GSS/GSR/GES) either on level transfer or on promotion.
  2. Other candidates that are not members of GSS, GORS, GSR, GES professions but possess and can demonstrate similar experience at the appropriate level. Badging opportunities will be available once in post for those who wish to apply.

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. A key priority is to become strongly data and evidence driven by ensuring it is used to improve our business performance and the justice system for our citizens.

The Data Science Hub

The Data Science Hub sits at the heart of MoJ’s push to use data to bear on some of the Ministry’s thorniest problems. We are a multi-disciplinary team of 90+ people from a range of professional and backgrounds. We most commonly use Python, R and Spark in our AWS Analytical Platform through our Macbooks, with data from the business that’s extracted, transformed and loaded by our data engineering teams.

We have delivered high impact data products that have been productionised and widely used across the business and adhoc insight that directly influences corporate, operational and policy decisions. These span the data science spectrum including automation, advanced visualisation, machine learning, data linking, natural language processing and optimisation. We are now collaborating with MoJ 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.

You can find more examples of our work and ways of working in the appendix section at the end of this document.


BOLD is a large and complex programme that consists of sharing data across government, building a linked dataset, and delivering 4 ‘demonstrator pilot projects’ that will use the linked dataset to tackle specific policy challenges across substance misuse, homelessness, victims of crime and reoffending. BOLD is an exciting cross-departmental programme funded by the Treasury’s Shared Outcomes Fund. This gives us the opportunity to truly work collaboratively across departmental boundaries, working as a single team with a single vision: deliver better outcomes for vulnerable populations through the use of linked data. If you like challenging problems with real-world impact and have always hoped government could learn to use data better, apply for this role and help us transform the use of data to drive outcomes and decision-making across government.

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 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 up to a month. Other candidates that pass the interview will be kept on a merit list for 12 months.


You will be assessed against the Civil service success profiles framework at interview stage:

  • Managing a Quality Service
  • Seeing the Big Picture

Please also refer to the CS Behaviours framework for more details at this grade 

Technical – Data science skills

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

  • data science expertise and technical leadership

For existing analysts from all professions, as well as the three civil service behaviours stated above, you will be assessed on two sets of professional competencies at interview

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