Salary: £70,000 - £85,000 (DoE)
Location: Hybrid - 2/3 days per week in a Central London office
Job Reference: J13015

Full UK working rights required - no sponsorship available
Immediate requirement - strong leadership and senior stakeholder skills

We are seeking an experienced, passionate, and highly motivated Senior Data Scientist to play a pivotal role in unlocking the value of customer data and shaping how it is used across the business. This is a senior, highly autonomous position, acting as the number two to the Director of Customer Data, where you will operate at a strategic level while remaining hands-on.

This is an excellent opportunity for a senior-level data scientist who wants real ownership, influence, and visibility, and to be part of a business at a transformative point in its data maturity.

The company has recently implemented a new Customer Data Platform (CDP) and is at a genuinely exciting stage of its data journey. You will be instrumental in helping define best practice, drive advanced analytics use cases, and influence how customer data is activated across products, CRM, and marketing.

While experience with personalisation and recommender systems would be highly desirable, it is not essential. The role is broader in scope and suited to someone who enjoys owning complex customer data problems end-to-end and shaping the direction of advanced data science initiatives.
________________________________________

The Role
• Act as a senior technical and strategic lead within the Customer Data team, working closely with (and deputising for) the Director.
• Take full ownership of your role, with the autonomy to shape priorities, define approaches, and mould the position to maximise impact.
• Lead the development of advanced machine learning solutions across customer data use cases, including (but not limited to) personalisation, segmentation, propensity modelling, and customer insight.
• Contribute to the evolution and activation of the newly implemented CDP, helping the organisation realise its full value.
• Own the full machine learning lifecycle - from problem definition and model design through to deployment, monitoring, and optimisation.
• Collaborate closely with CRM, marketing, product, engineering, and regional teams to ensure solutions are aligned to business goals.
• Partner with data engineering and platform teams to ensure scalable, robust, and production-ready solutions.
• Act as a senior stakeholder, able to clearly communicate complex concepts and influence decision-making at all levels.
_______________________________________

Skills & Experience
• Strong, hands-on experience in machine learning and applied data science within customer or commercial domains.
• Experience with recommender systems, personalisation, or deep learning is desirable but not essential.
• Solid Python skills and experience with ML libraries such as pandas, numpy, scipy, scikit-learn, TensorFlow or PyTorch.
• Experience working across cloud environments (GCP, AWS, or Azure) and analytics platforms such as Dataiku.
• Good understanding of MLOps practices, including deployment, monitoring, and retraining pipelines.
• Proven ability to work cross-functionally with marketing, CRM, product, and engineering teams.
• Excellent communication, leadership, and stakeholder management skills.
• Experience operating in a global or multi-regional environment is a plus.

How Many Machine Learning Tools Do You Need to Know to Get a Machine Learning Job?

Machine learning is one of the most exciting and rapidly growing areas of tech. But for job seekers it can also feel like a maze of tools, frameworks and platforms. One job advert wants TensorFlow and Keras. Another mentions PyTorch, scikit-learn and Spark. A third lists Mlflow, Docker, Kubernetes and more. With so many names out there, it’s easy to fall into the trap of thinking you must learn everything just to be competitive. Here’s the honest truth most machine learning hiring managers won’t say out loud: 👉 They don’t hire you because you know every tool. They hire you because you can solve real problems with the tools you know. Tools are important — no doubt — but context, judgement and outcomes matter far more. So how many machine learning tools do you actually need to know to get a job? For most job seekers, the real number is far smaller than you think — and more logically grouped. This guide breaks down exactly what employers expect, which tools are core, which are role-specific, and how to structure your learning for real career results.

You must send clear signals of relevance, delivery, impact, reasoning and readiness for production — and do it within the first few lines of your CV or portfolio.
