Senior Data Scientist

London Hybrid (2 days x week)

This is an opportunity to join a growing Data and AI business building production grade machine learning and LLM driven products for financial services and trading environments. The role offers exposure to both proprietary software and consultancy led problem solving, with real ownership over models that move into live use rather than staying at proof of concept stage.

The Company
They are a well established Data and AI organisation that has been operating successfully for several years, combining proprietary tooling with consultancy expertise. Their products support data driven decision making across financial services, including advanced analytical assistants and conversational AI solutions. The business is technically led, collaborative, and focused on building high quality, scalable machine learning systems.

The Role
You will work as part of a close knit data science team, contributing to the design, development and deployment of machine learning and LLM based solutions.
Responsibilities include:
  • Designing and building machine learning models used by trading and financial services clients.
  • Developing NLP and LLM powered chat engines that surface insights and factual answers from complex data.
  • Fine tuning deep learning and large language models, including extraction and parameter optimisation.
  • Working end to end on models that are taken through to production rather than remaining as prototypes.
  • Contributing to products such as data assistance tools, website chatbots and analytical AI platforms.
Your Skills and Experience
  • Hands on experience building and deploying machine learning models end to end.
  • Experience with LLMs, NLP, conversational AI, RAG pipelines and model fine tuning.
  • Understanding of production grade ML workflows and CI CD principles.
  • Experience building chatbots or NLP driven chat engines used in live environments.
  • Comfortable working independently and taking ownership of complex problems.
What They Offer
  • Hybrid working with two days per week in a London office.
  • Remote flexibility for candidates based in the North, with office visits around twice per month.
  • The chance to work on impactful AI products used in real commercial and trading environments.
  • A supportive team structure with senior mentorship and clear technical progression.
