Machine Learning Developer at ARC IT Recruitment, Remote, £Contract Rate

Machine Learning Developer
Contract outside IR35
Remote (UK)
Circa £500 per a day outside IR35

A world-renowned brand is looking for a hands-on Machine Learning Developer to join its ML team on a contract basis.

You'll build models for valuation, client lifetime value, recommendations and personalisation, and image understanding. You'll own each model from end to end: exploring the data, building and validating the model, and turning it into a production service that developer teams across the business rely on.

The stack is Databricks and Azure. The team cares a lot about reproducibility, so clean experiment tracking and versioning are part of the job, not an afterthought.

This is a hands-on modelling role, not a team lead position. We're open on seniority. Practical experience in the areas below matters more than years in the industry.

What you'll bring

• Strong Python and the standard modelling and analysis stack
• Hands-on experience with classical regression and other supervised models, built and validated yourself
• Experience in at least one of these: customer lifetime value (CLTV) modelling, recommender systems, or deep learning
• Solid validation habits, including evaluation metrics, avoiding data leakage, and knowing when a result is real
• Experience getting models into production, ideally including monitoring and retraining, with experiment tracking and model versioning
• The ability to explain results clearly to non-technical colleagues, including through good data visualisation
• Good engineering habits, including version control and testing

Nice to have

• Databricks, MLflow or a similar ML platform
• Azure
• Embedding-based approaches and computer vision
• LLMs or agentic approaches, alongside a solid classical ML base
• Uncertainty quantification, quantile regression or Bayesian methods

This role suits someone curious and collaborative. You'll be happy to prototype ideas before anyone asks, share work in progress, and help colleagues build their ML knowledge.

Contract, outside IR35 fully remote within the UK.
