Data Scientist – Data Analytics / Visualisation Office for National Statistics

Job description

As a Data Scientist/Analyst at the Campus, you will have a passion for data science and using it for the public good. You will relish the challenge presented by delivering benefits from the broad span of Campus projects.

You will lead or work within multi-disciplinary delivery teams and collaborate with others in government, industry, academia, and charities, both in the UK and internationally. You will research, design, build and improve digital and data products. You will also contribute to building capability in data science through research, mentoring and training.

The presently advertised roles will place candidates in a team using data science and analysis to deliver insights about population mobility and its interactions with economy, environment and society. However, we encourage applications from those interested to work in other areas of the Campus or wider ONS. A reserve list of applicants will be held for up to 12 months and may be used to fill any vacancies that arise in other teams.

Data Scientists / Analyst (appointed at the Civil Service grade of Senior Executive Officer) are proficient in data science and/or data modelling and analysis. They have recognised ability in a number of data science specialisms and provide detailed technical advice on their area of expertise. They draw on other technical and analytical standards from across government and industry. They promote and present data science work both within and outside of the organisation. They engage with stakeholders to demonstrate the value of data science and propagate data science skills in other teams. They line manage and mentor Junior Data Scientists.

As a Data Scientist/ Analyst with the Data Science Campus you will:

• Work as part of a cross-disciplinary team to deliver ground-breaking data science projects in population mobility; you also contribute in one or more of other core Campus themes: the economy, the environment, society.
• Deliver innovative data science for the public sector, exploring and applying new data sources, tools and techniques or approaches to meet our clients’ needs, and using your coding and analytical skills.
• Develop software tools, hardware infrastructure or data products that exploit state of the art research to place technology in the hands of the operational users.
• Use Agile project delivery methodology to deliver effectively and efficiently. Ensure work delivers value by understanding and addressing user needs.
• Write and publish code to quality standards. Contribute to technical reports, working papers, and journal articles.
• Develop and deliver regular statistical or analytical outputs.

There may be some line management associated with these posts. Some travel to other Campus and Government locations will be required at both grades.

Although remote workers will not be attached to an office location, there is an expectation that you will occasionally attend meetings or other activities on-site.
