- let our Talent team know if you need any reasonable adjustments throughout the recruitment processJob DescriptionAs a Senior AI Engineer, you will be part of the AI Platform team, helping to build and scale the shared foundations that enable AI capabilities across ASOS.

The primary focus of this role will be contributing to the Agentic AI Platform initiative, alongside other core AI platform capabilities as the platform evolves. This role is focused on the platform layer, rather than individual business use cases.

You will design and implement shared capabilities, standards, reusable templates and reference implementations for agentic AI on Azure, enabling engineering teams across ASOS to safely design, deploy and operate AI agents at enterprise scale.

Working closely with Product teams, Cloud Infrastructure, Security and engineering teams, you will help establish the patterns and capabilities that make AI secure, observable, reliable and reusable by default.

You will also contribute to the production foundations needed to operate AI capabilities reliably, including LLMOps, model access patterns, prompt and agent lifecycle practices, evaluation, observability and secure enterprise integration.

This is a hands-on engineering role where the capabilities you build will be used by other teams across ASOS, helping to establish consistent engineering practices for building and operating AI at scale.
