Why be a Data Engineer at THG? 

THG is building the engineering capability that will sit beneath every analytics, data science and AI initiative across the business. As a Data Engineer within our Engineering & Governance pillar, you will work within one of three domain-aligned engineering teams — Customer, Commercial or Operations — helping to build and evolve the structured domain datasets that the business depends on.

This is an early-career role with real responsibility. You will be working alongside a Senior Data Engineer and Engineering Lead on some of THG's most important data challenges: consolidating fragmented data sources, building reliable pipelines, and moving the business towards a consistent, trustworthy foundation for how we manage our data.

We are not looking for someone who has done this all before — we are looking for someone technically capable, curious, and genuinely motivated by the craft of data engineering. If you want to build things that matter and develop quickly in a fast-moving environment, this is the right role.

What you'll do:

Pipeline Development

• Build and maintain data pipelines within your domain — extracting, transforming and loading data from source systems into structured domain datasets in BigQuery
• Work to the architectural patterns and standards set by the Engineering Lead — applying consistent approaches to how data is ingested, transformed and stored
• Support the migration of existing pipelines from legacy on-prem SQL Server infrastructure to BigQuery and Dataform
• Apply version control (Git) as standard practice — all code is reviewed, documented and maintained properly

Domain Dataset Development

• Contribute to the build-out of your aligned domain dataset — helping to consolidate disparate data sources into a structured, reliable and well-documented data asset
• As an example in the Customer domain: working towards the foundations of a unified customer dataset, bringing together data from multiple source systems into a consistent, queryable structure
• In Commercial: building and maintaining the datasets that power category, brand and trading analytics — ensuring consistency in how commercial data is structured and stored
• In Operations: developing the data pipelines and structures that support supply chain, logistics and fulfilment analytics
• Identify and flag data quality issues within your domain — working with the Data Governance Lead on standards and resolution

Collaboration

• Work closely with your Senior Data Engineer and the Engineering Lead — asking questions, learning fast and contributing to the team's technical decisions
• Engage with analytics and data science teams who consume your domain's data — understanding their requirements and ensuring what you build is useful
• Participate in code reviews — both having your work reviewed and, as you develop, reviewing others
• Use AI tools effectively to accelerate your development work — we expect AI-assisted coding and pipeline development to be part of how the team works

What skills and experience do I need for this role?

Essential

• Solid SQL skills — able to write intermediate to advanced queries and comfortable working with relational databases
• Python — working knowledge sufficient for data manipulation, scripting and pipeline development
• A genuine passion for data engineering — you find the challenge of getting data right genuinely interesting
• Attention to detail and a methodical approach — data engineering is unforgiving of sloppiness
• Eagerness to learn — this role will develop quickly and we want someone who grabs that opportunity

Desirable

• Exposure to BigQuery, Dataform or equivalent cloud data tools
• Familiarity with version control (Git)
• Experience with or understanding of data pipeline design patterns
• Degree in Computer Science, Mathematics, Engineering or a related discipline
• Any experience applying AI tools in a technical context
