Machine Learning Engineer (Hiring Immediately)

Company Description

We’re ASOS, the online retailer for fashion lovers all around the world.

We exist to give our customers the confidence to be whoever they want to be, and that goes for our people too. At ASOS, you’re free to be your true self without judgement, and channel your creativity into a platform used by millions.

Everyone needs some help showing up as their best self. We're Disability Confident Committed - Let our Talent team know if you need any adjustments throughout the process in whatever way works best for you.

Job Description

We’re looking for a Machine Learning Engineer to join our Search & Recommendations team , where we build the systems that power how customers discover products across ASOS.

This is a highly impactful space - our recommendation and ranking models sit directly in the customer journey, powering experiences like “similar items”, “people also viewed”, and real‑time personalised journeys that adapt as customers browse.

These systems run at global consumer scale, continuously learning from customer behaviour - including clicks, views, and interactions - to dynamically rank and surface the most relevant products in real time.

Working in a cross‑functional team of machine learning engineers, data scientists, and product partners, you’ll help take models from experimentation into robust, production systems that directly influence customer experience and commercial outcomes.

You’ll also contribute to the next generation of discovery at ASOS - from sequence‑based recommendation models to emerging areas like outfit generation and AI‑driven styling experiences.

What you'll be doing

• Designing and building production-grade machine learning systems that power personalisation and discovery
• Developing and improving recommender systems and ranking models used across the customer journey
• Deploying models into batch and real-time environments, ensuring scalability, reliability, and performance
• Collaborating with data scientists to translate experimental models into production-ready systems
• Monitoring, evaluating, and iterating on models using real-world behavioural signals
• Contributing to engineering best practices, tooling, and shared ML platform capabilities
