The Role

MVF is seeking an exceptionally skilled and driven Senior Data Scientist to deliver significant commercial value. You will leverage your extensive Data Science knowledge and experience in diverse commercial environments to build new products and define the ‘art of the possible,’ shaping the ML roadmap in line with our Data Strategy.

You will be pivotal in building our Data Science and Machine Learning capabilities, with the potential to hire a team in the future. You will be responsible for all Data Science areas. These are currently problems that we are working on:

  • Imbalanced classification - predicting the value of leads
  • Optimisation (e.g., Linear programming) - optimising which leads / products we sell to which client
  • Forecasting - predicting client demand
  • Experimentation
  • Foundational models (LLMs) - Using LLMs to extract information from multimodal data sets

You will be communicative, commercially-minded, with a strong team-spirit. You will enjoy collaborating with stakeholders, as you will be delivering value across the business, from Paid Marketing to Operations and Sales.

Reporting to the Head of Data, you will collaborate and have support from Analytics Engineering teams to build and maintain pipelines and from Software Engineering teams to productionize models. You will have Product Management support from a Data PM and Head of Data; however the ideal candidate will relish the opportunity to understand their stakeholders more deeply and define where they think they (and Data Science) can add the most value.
