Machine Learning Researcher

Principal Machine Learning Scientist | London | Hybrid

I’m working with a leading global technology company looking to hire a Principal Machine Learning Scientist into a growing ML organisation in London.

This is a senior, hands-on role focused on designing and scaling machine learning systems that power personalised user experiences and intelligent decision-making across a large-scale platform.

What you’ll be working on

• Ranking, retrieval and recommendation systems
• Representation learning and embeddings
• Large-scale ML architecture and system design
• Production ML pipelines and real-time inference
• Experimentation, optimisation and model performance
• Big data technologies including Spark
• Technical leadership across ML and engineering teams

We’re looking for people with

• Experience in Machine Learning or Applied Science
• Strong experience building ML systems from research through production
• Deep expertise in recommendation systems, ranking or retrieval
• Representation learning and embedding techniques
• ML system design at scale
• Experience working with large, complex datasets
• MSc or PhD in Machine Learning, Computer Science or a related field
• A track record of leading complex technical initiatives

We’re hiring across multiple senior ML positions, so there’s also interest in exceptional candidates at Senior Machine Learning Scientist level.

If you’re working on large-scale recommendation, search or ranking problems and are open to hearing about a new opportunity, I’d be happy to share more.
