Are you an experienced Senior Data Scientist passionate about solving real-world challenges and making a tangible impact? We're have a phenomenal new opportunity for someone to help shape the future of connectivity for over 46 million customers.

In this high-impact role, you will design, implement, and optimise predictive models that play a direct role in improving customer satisfaction and driving meaningful business outcomes. You'll be working on end-to-end model development, from the initial concept and data exploration stages through to deployment and ongoing refinement.

This involves using sophisticated machine learning and statistical techniques to address key customer challenges, identifying and resolving issues before they arise, and reducing churn while enhancing the overall experience. Through deep data exploration and feature engineering, you will uncover the drivers behind customer behaviour and help guide strategic decisions.

Collaboration is central to this position. You’ll work closely with teams across engineering, product, and marketing to ensure that business needs are translated into effective, scalable data science solutions. Your contributions will extend beyond modelling, playing a key role in shaping our MLOps strategy to ensure reliability, performance, and long-term value.

As member of our high-performing data science and insight team, you’ll also have the opportunity to mentor others, share your expertise, and foster a culture of continuous learning and innovation.

Success in this role requires a combination of technical expertise, strategic thinking, and a drive to create real business impact. It’s well suited to someone who not only develops advanced models but also understands how to deploy and operationalise them effectively in a real-world setting.
