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.

The Skills Gap in Data Science Jobs: What Universities Aren’t Teaching

Data science has become one of the most visible and sought-after careers in the UK technology market. From financial services and retail to healthcare, media, government and sport, organisations increasingly rely on data scientists to extract insight, guide decisions and build predictive models. Universities have responded quickly. Degrees in data science, analytics and artificial intelligence have expanded rapidly, and many computer science courses now include data-focused pathways. And yet, despite the volume of graduates entering the market, employers across the UK consistently report the same problem: Many data science candidates are not job-ready. Vacancies remain open. Hiring processes drag on. Candidates with impressive academic backgrounds fail interviews or struggle once hired. The issue is not intelligence or effort. It is a persistent skills gap between university education and real-world data science roles. This article explores that gap in depth: what universities teach well, what they often miss, why the gap exists, what employers actually want, and how jobseekers can bridge the divide to build successful careers in data science.

Data Science Jobs for Career Switchers in Their 30s, 40s & 50s (UK Reality Check)

Thinking about switching into data science in your 30s, 40s or 50s? You’re far from alone. Across the UK, businesses are investing in data science talent to turn data into insight, support better decisions and unlock competitive advantage. But with all the hype about machine learning, Python, AI and data unicorns, it can be hard to separate real opportunities from noise. This article gives you a practical, UK-focused reality check on data science careers for mid-life career switchers — what roles really exist, what skills employers really hire for, how long retraining typically takes, what UK recruiters actually look for and how to craft a compelling career pivot story. Whether you come from finance, marketing, operations, research, project management or another field entirely, there are meaningful pathways into data science — and age itself is not the barrier many people fear.

How to Write a Data Science Job Ad That Attracts the Right People

Data science plays a critical role in how organisations across the UK make decisions, build products and gain competitive advantage. From forecasting and personalisation to risk modelling and experimentation, data scientists help translate data into insight and action. Yet many employers struggle to attract the right data science candidates. Job adverts often generate high volumes of applications, but few applicants have the mix of analytical skill, business understanding and communication ability the role actually requires. At the same time, experienced data scientists skip over adverts that feel vague, inflated or misaligned with real data science work. In most cases, the issue is not a lack of talent — it is the quality and clarity of the job advert. Data scientists are analytical, sceptical of hype and highly selective. A poorly written job ad signals unclear expectations and immature data practices. A well-written one signals credibility, focus and serious intent. This guide explains how to write a data science job ad that attracts the right people, improves applicant quality and positions your organisation as a strong data employer.
