We’re partnering with a well‑established eCommerce organisation based in Leicester that is expanding its data capability. They’re looking for a Technical Lead Data Scientist to play a key role in shaping, delivering, and scaling high‑impact data science solutions across the business.

This is a hands‑on leadership role where you’ll combine deep technical expertise with the ability to guide teams and influence senior stakeholders.

What you’ll be doing:

  • Lead end‑to‑end development, deployment, and optimisation of data science projects in a production environment.
  • Design and build advanced machine learning models using customer data, including churn prediction, customer segmentation, and recommendation systems.
  • Provide technical leadership and mentorship to data scientists, setting best practices and raising overall capability.
  • Collaborate closely with stakeholders across the business, from C‑suite executives to junior team members, translating complex technical concepts into clear, actionable insights.
  • Help shape the data science roadmap and contribute to strategic decision‑making within the organisation.

What we’re looking for:

  • 4+ years of commercial experience working as a Data Scientist.
  • Strong programming skills in Python and SQL, with hands‑on experience using PyTorch and TensorFlow.
  • Proven experience working on customer‑focused or personalisation‑driven data science problems (e.g., churn, recommendations, segmentation).
  • Excellent communication skills, with the confidence to engage and influence both technical and non‑technical stakeholders.
  • Experience leading projects or providing technical direction to others (formal leadership not essential).
