Data/Backend Engineer - Retail Media

Hungry for a challenge?

That's good, because at Just Eat Takeaway (JET) we have abundant opportunity, or, as we say, everything is on the table. We are a leading global online food delivery marketplace. Our tech ecosystem connects millions of active customers with hundreds of thousands of connected partners in countries across the globe.

Our mission? To empower every food moment around the world, whether it's through customer service, coding or couriers.

About this role

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.
