Your Role: AI Python Developer

This role sits in the Global:IQ team, building our next-generation intelligence platform. Global:IQ brings together 1st party and partner data, tools and capabilities to turn data into audience understanding and optimised, data-led media plans across audio and out-of-home.

As an AI Python Developer at Global, you will be a key technical contributor, building scalable backend systems that enable our AI and machine learning models to run efficiently and reliably in production.

Key Responsibilities

  • Backend Engineering (50%): Design, build and maintain robust APIs and microservices using Python, FastAPI and Postgres to power the Global:IQ platform.

  • Data Engineering (20%): Develop and support data pipelines and integrations that enable Global:IQ’s AI and analytics use cases.

  • Infrastructure & Data Warehousing (30%): Architect and manage integrations with cloud platforms (AWS) and Snowflake, ensuring data accessibility, reliability and query performance.

What You’ll Love About This Role

Think Big: Help build the “brain” of the company, working on end-to-end AI and data developments that directly shape how we plan and deliver media.

Own It: Take features from idea to production, advocating for modern, AI-enabled engineering practices and high-quality software development.

Keep it Simple: Turn complex data and modelling requirements into clean, well-structured services and APIs that are easy to understand and maintain.

Better Together: Work in a startup-style, fast-paced environment backed by the data assets and resources of a major media and entertainment company, collaborating closely with data scientists, engineers and product teams.

What Success Looks Like

In your first few months, you’ll have:

  • Built a strong understanding of the Global:IQ architecture, data flows and key use cases.

  • Delivered your first production services and pipelines at pace, using modern AI-accelerated development practices.

  • Played a key role in bringing new Global:IQ product features into production for real customers.

  • Established yourself as a technical voice in the team, contributing to standards, best practice and ways of working.

What You’ll Need

  • Backend Engineering Experience: Around 3+ years’ experience in backend engineering, ideally in product or platform teams.

  • Python & APIs: Strong proficiency in Python, with hands-on experience using FastAPI (or similar frameworks) and Postgres in production.

  • Cloud & Data Platforms: Practical experience with cloud platforms and modern data warehouses, ideally including Snowflake.

  • Data & AI Focus: Experience leading or contributing to data and AI-driven projects from conception to deployment, and an understanding of systems that support data workflows.

  • Modern Engineering Practices: Comfortable using agentic and AI-accelerated tools (e.g. Claude Code, Copilot-style tools) and working in fast-moving, highly accountable teams.

  • Outcome Orientation: A passion for using data and intelligence to improve ad campaign efficiency and demonstrate the value of media investment.
