Sheffield, United Kingdom | Posted on 03/01/2026
Lithe Transformation is looking to hire a Senior Data Scientist to support our growing AI and LLM practice in the north of England. Based within daily striking distance of our client's Sheffield offices, this hybrid role requires an onsite presence the majority of the time.
This is not a strategy‑heavy or stakeholder management position. It is a hands‑on, engineering‑led data science role focused on deep modelling, heavy data processing, scenario modelling and building executive‑level dashboards that drive real business decisions.
The Role
You will work as part of a mature and established data insights team, contributing directly to high‑impact analytical initiatives. The core focus includes:
- Advanced data modelling and statistical analysis
- Heavy data crunching and scenario modelling
- Building robust executive dashboards and decision frameworks
- Working hands‑on with transformer architectures and LLM layers
- Engineering‑grade data science delivery within a financial services setting
This is “hardcore” data science engineering — suited to someone who enjoys building, modelling and solving complex quantitative problems rather than operating primarily in stakeholder or governance layers.
Experience Required
- 5+ years of hands‑on data science experience (5–10+ ideal)
- Strong background in data modelling and large‑scale data processing
- Practical experience working with LLMs, transformer models or adjacent architectures
- Proven ability to deliver scenario‑based modelling outputs
- Experience building dashboards and executive‑ready analytical outputs
- Financial services experience is advantageous but not mandatory
Soft skills are important but this is not a heavily stakeholder‑facing role. The team environment is already established and collaborative.
We are offering a basic salary of £76k.
PLEASE NOTE THAT WE ARE NOT ABLE TO OFFER VISA SPONSORSHIP OF ANY KIND FOR THIS ROLE, EITHER NOW OR IN THE FUTURE. All applicants must have current authorisation to work permanently in the UK, unrestricted.
