Salary: £50,000 - £80,000

Step into a role where clean code, smart design, and real ownership come together to shape the future of ad-fraud prevention.

The Opportunity

In this role, you'll help shape a platform that processes large volumes of data and safeguards digital advertising integrity. You'll design simple, effective solutions, write maintainable Python code, and ensure reliability through testing and observability practices. The work spans implementation, documentation, and hands-on operational responsibility. Collaboration is key, but you'll have freedom to drive your own tasks and influence the team's development standards. It's an opportunity to deepen your engineering fundamentals within a supportive, quality-driven culture.

Roles and Responsibilities

This role sits within a small, high-impact platform team responsible for building and scaling the backend systems that power a machine-learning driven ad-fraud prevention platform. You'll work extensively with Python and large-scale data sets, supporting model training on billions of data points, delivering features to data science teams, and helping launch new models, tracking capabilities, and integration's across major ad platforms.

The work spans everything from developing big-data pipelines on cloud infrastructure (AWS, Redshift, or equivalent) to supporting greenfield projects like new affiliate products and upcoming channel integration's. You'll contribute to a fast-paced engineering environment that deploys to production twice a week, where processes exist but can evolve and where autonomy and technical ownership are central.

Interview Process:

  1. 30 Minute Chat - Introductory Conversation
  2. Technical Challenge - Live Coding Technical Session
  3. Cultural Fit

Join a fast-moving engineering team working with Python, big data, and cutting-edge ML to power a high-scale ad-fraud prevention platform, apply today.
