About the job

Summary

Do you want to help analysts answer the questions of the day by providing them with the data they require? Do you want to play your part in the transformation of how statistics are produced to help Britain make better decisions?

The Office for National Statistics (ONS) is the UK’s largest producer of official statistics, covering a range of key economic, social and demographic topics. These include measuring changes in the value of the UK economy, estimating the size, geographic distribution and characteristics of the population, and providing indicator of price inflation, employment, earnings, crime and migration.

Job description

This is an exciting time to join ONS, we are currently recruiting for a number of Data Engineers across the Higher Executive Officer (HEO) and Senior Executive Officer (SEO) grades to join our growing community within the following business areas:

Post 1 - Census Data Transformation (HEO Post) (Fixed term 1 post, contract available until 31 March 2023)
This team is responsible for the processing of data from the 2021 Census so that outputs can be produced to inform decisions by Government, Local Authorities, and the wider user base. The team are responsible for the end to end data journey through data preparation and statistical processing up to the creation of a complete unit record dataset upon which all outputs are based.

Post 2 – Covid Infection Survey Data Processing - Social Survey Transformation (HEO post) (Fixed term 1 post, contract available until 31 July 2022)
The COVID19 Infection Survey (CIS) within ONS, provides statistical analysis on the COVID19 pandemic for Government and Research purposes. The Data Processing Pipeline (DPP) receives data from multiple sources, processes this data in variety of ways, then provides the cleaned / linked data to several Analysis teams for their investigation. The DPP within CIS is an extremely busy function, working to demanding objectives, with rapid development and very short cycle times.

The role is responsible for the technical development and implementation of the processing pipelines specified and designed in conjunction with the COVID analysis teams. You will be working with a small coding team and a wider analysis team to identify the best ways of ingesting and processing the data received.

Post 3 - Data Operations and Engineering (HEO post) (Fixed term 4 posts and 1 permanent post available, contracts available are: Posts 1 and 2 until 31 March 2022, Posts 3 and 4 until 31 December 2023 and Post 5 is offered on a permanent contract)
This team develops and delivers the programmes to import, validate and structure key administrative data that flow into ONS under the Digital Economy Act (DEA). The role is based in an expanding and busy team that supports key business areas from Social Surveys to the Economic Accounts.

Post 4 - Development, Delivery and Support Division (SEO post) (Fixed term 1 post, contract available until 31 March 2022)
This multi-disciplinary role broadly supports the aim to modernise the way in which economic statistics are developed; providing data science supported evidence and data engineering support to projects. At the outset of each project, staff in this role will work from an initial design or concept phase, to successful implementation of both regularly published statistics and ‘one-off’ experimental sets of statistics.

This involves data interrogation, the coding of functions that conduct statistical or data manipulation tasks, as well as the coding of data processing pipelines. The team are developing better economic statistics using new tools and techniques. That primarily includes a new cloud computing platform (DAP), making use of the Spark libraries to process and analyse large datasets (Python and Spark are the main tools that are used in the team) and secondarily supporting smaller projects with local systems built upon Python or R libraries. With this, we can apply data science and data engineering techniques to produce timelier, more granular and more insightful statistics.

A key aim for staff in this role is to think about how new technology and methods can be applied to the development of economic statistics in the future. Individuals will be able to have the time and space to develop their skills and conduct research, with the aim of getting experimental statistics or analysis out to stakeholders and the wider public sooner.

Responsibilities

As one of our HEO Data Engineers, you will carry out a wide range of activities with responsibilities that may include:
• Working with subject matter experts to design, build, test and implement processing solutions that will provide high quality data for analysis;
• Working collaboratively with the relevant experts in ONS to ensure corporate standards are understood and implemented in all development activity;
• Work with Data Architecture to ensure data are fully documented using corporate tools and standards;
• Coordination of activities within the team, internal delivery partners within ONS and end users of the data;
• Possibly carry out the line management of staff, this may involve matrix management;
• Ensure that business continuity is considered within the day to day work;
• Liaise with Data Architecture to ensure corporate data management principles are followed;
• Address blockers actively seeking solutions to remove them and proposing alternative routes to delivery;
• Promote a frequent incremental delivery approach;
• Digest, troubleshoot and understand a range of large administrative and wider non-survey data series working with the Senior lead in the area;
• Providing a core coding resource for the rising demand in delivering the underlying processes and code to validate and build key administrative data series. This will involve specifying history, validating data and building coherent and accessible data structures on a series-by-series basis for distribution to users inside and outside of the ONS;
• Support the administrative data engineering strategy, working closely with managers and other teams in ONS Data Acquisition and Operations Division in implementing and developing standard data validation, structuring and standardisation protocols to non-survey data. This is to enable business-wide roll-out of the data and ensure it is used consistently across ONS;
• To develop, test and document the end-to-end process for developing ETL data pipelines to ingest and transform large administrative and commercial data flows as they come into the ONS;
• Supporting (if experienced users of Cloudera tools), other areas of ONS, working collaboratively with teams in validating and linking key non-survey data sources. The key goal is to contribute to the data’s broader development and alignment by enabling business areas to integrate the data to produce better and more timely statistical outputs.

As a Senior Executive Officer Data Engineer, you will carry out a wide range of activities with responsibilities that include:
• Work with Economic Statistics experts to understand what statistics need to be produced;
• Conduct data analysis and visualization of the key datasets used to produce the required statistics;
• Produce initial design documents and diagrams for data processing systems, considering the statistical or data processing methods that are needed for the task, as well as the design of the overall data model;
• Contribute to Python libraries of statistical or data processing functions, ensuring that any functions are well unit tested;
• Write Python code that will systemize the processing of data, based on initial design documents. This includes writing unit / integration tests and managing versions of code with Git;
• Report on the progress of prototype systems to customers, clearly articulating the impact of various data processing steps on the outputs;
• Maintain and review documentation for statistical and data processing functions, as well as data processing pipelines;
• Manage working relationships with stakeholders across Economic Statistics, keeping people up to date on progress and highlighting any risks with projects;
• Apply agile project management principles to managing projects and tasks on a day-to-day basis.
