Graduate Data Engineer

Fospha is the measurement system enterprise retail and ecommerce brands run their business on. We give marketing teams one clear, daily view of what's actually working — across every channel and everywhere they sell, from their website to Amazon and Tik Tok Shop — down to the level of a single ad or piece of creative. It replaces guesswork and gut feel with a number marketing, finance and agencies can all trust and act on.

Brands including Dyson, Gymshark, Adanola and Huel use Fospha up to 25 times a day to decide where budget should move next. We've spent over a decade building this, with more than $40 billion in marketing spend now optimised through the platform — and we're scaling fast across London, Mumbai and Austin.

Fospha's measurement products run on data pipelines that process marketing spend and performance data for brands you'll recognise. You'll get exposure across our core data engineering work streams: large-scale SQL/dbt transformation pipelines, data ingestion services, and pipelines that turn aggregated data into insights served through APIs. You'll work alongside data engineers, analysts, and AI agents as part of our AI-first operating model, with senior engineers supporting you as you build real ownership.

This role suits a recent graduate (or someone with a strong personal/academic project record) who's curious about data pipelines and wants to learn by shipping real, production code from day one.

• Write and maintain dbt models and SQL as part of our production data engineering pipelines, learning the transformation patterns we build on
• Help build and maintain Python-based data ingestion services, with guidance from senior engineers
• Contribute to pipelines that move data from ingestion through transformation to the APIs that serve it
• Write clean, tested code and get comfortable with code review from both sides — giving and receiving feedback
• Debug data quality issues systematically, learning to trace problems back through the pipeline
• Get exposure to our cloud infrastructure and understand how it supports the pipelines you work on
• Work with AI agents as part of our AI-first operating model, learning to write clear specifications that shape high-quality, AI-assisted engineering work
• Collaborate with data engineers, analysts, and product stakeholders to understand what the data needs to support
