£73,176 per year – estimated
Full time
NEW
We're looking for an experienced Data & Backend Engineer to join the Insights and Enablement team. This newly established team sits within Retail Media, part of Jet Ventures, and plays a pivotal role in shaping how we use data from our Customer Data Platform (CDP), enabling advanced audience segmentation, data visualisation, dashboards, and surfacing insights across Retail Media and the broader JET organisation.
This is not a typical Data/Backend Engineer – you'll work at the intersection of software engineering, data engineering and applied AI/ML, designing, deploying, and scaling production systems that bring advanced data science research to production. You'll partner closely with data scientists, product managers, analysts and engineers to transform prototypes into reliable, high‑performing services that deliver impact for advertisers and customers at scale.
We're seeking self‑starters, who are passionate about data, experimentation and emerging technologies in machine learning and AI, and as a senior member of the team, you'll do more than code – you'll help shape best practices, mentor others, and raise the technical bar.
Location: Hybrid – 3 days a week from our London office & 2 days working from home
Reporting to: Technology Manager

* Experience as a Data Engineer and/or Backend Engineer with a track record of building and shipping large‑scale, real‑world data systems
* Strong Python coding skills and a deep understanding of distributed systems and backend services

* Experience with large‑scale data platforms (e.g., Spark, Kafka, Flink, BigQuery) and cloud environments, with a preference for AWS or GCP
