Data Mapping & Integration Analyst (Contract)

6-12 months | Outside IR35 | £510 per day | Hybrid - Midlands

The Company

Our client is embarking on a major application rebuild programme to modernise the technology behind its customer options and configuration process. The existing platform has served the business well but suffers from a fragmented data structure that limits scalability and insight.

This project is focused on re-engineering the data layer to create a clean, efficient foundation for operational performance and downstream analytics.

The Role

The Data Mapping & Integration Analyst will play a key role in defining how data flows through this new platform, from source systems through to the central data environment.

Working closely with the Data, Architecture, and Application Development teams, this individual will ensure the new system is designed with robust, future-proofed data structures that support both operational use and analytical value. This is a hands-on data role, not a reporting or visualisation position, focused on understanding how data is captured, structured, and transferred between systems.

Key Responsibilities

Analyse and document as-is data structures, including JSON-based and SQL sources.
Design and define the to-be data model, including entity relationships, data dictionaries, and lineage.
Develop and maintain detailed source-to-target mappings to support data migration and system integration.
Collaborate with solution architects, developers, and business SMEs to ensure the data model supports both operational processes and analytical requirements.
Identify and resolve data quality and consistency issues early in the project lifecycle.
Provide input to design documentation, data governance standards, and technical specifications.
Act as the data SME across the application rebuild, ensuring data considerations are embedded from design through delivery.

Skills & Experience

Strong experience in data analysis, data modelling, and data mapping within application rebuilds or migration projects.
Excellent understanding of relational databases (SQL) and working knowledge of JSON or similar semi-structured formats.
Demonstrable experience in producing source-to-target mappings, data dictionaries, and integration specifications.
Proven track record of collaborating with technical and business teams to align data design with functional outcomes.
Awareness of data quality, lineage, and governance principles.
Previous experience working in complex operational environments such as retail, manufacturing, property, or ERP/CPQ systems is advantageous

Why Data Science Careers in the UK Are Becoming More Multidisciplinary

Data science once meant advanced statistics, machine learning models and coding in Python or R. In the UK today, it has become one of the most in-demand professions across sectors — from healthcare to finance, retail to government. But as the field matures, employers now expect more than technical modelling skills. Modern data science is multidisciplinary. It requires not just coding and algorithms, but also legal knowledge, ethical reasoning, psychological insight, linguistic clarity and human-centred design. Data scientists are expected to interpret, communicate and apply data responsibly, with awareness of law, human behaviour and accessibility. In this article, we’ll explore why data science careers in the UK are becoming more multidisciplinary, how these five disciplines intersect with data science, and what job-seekers & employers need to know to succeed in this transformed field.

Data Science Team Structures Explained: Who Does What in a Modern Data Science Department

Data science is one of the most in-demand, dynamic, and multidisciplinary areas in the UK tech and business landscape. Organisations from finance, retail, health, government, and beyond are using data to drive decisions, automate processes, personalise services, predict trends, detect fraud, and more. To do that well, companies don’t just need good data scientists; they need teams with clearly defined roles, responsibilities, workflows, collaboration, and governance. If you're aiming for a role in data science or recruiting for one, understanding the structure of a data science department—and who does what—can make all the difference. This article breaks down the key roles, how they interact across the lifecycle of a data science project, what skills and qualifications are typical in the UK, expected salary ranges, challenges, trends, and how to build or grow an effective team.
