Over 400 carwowers from 25 nationalities work with us in the UK, Germany, Spain and Portugal. One of our goals for 2023 is to become a Top 10 European Start-Up to work for.

About the role

Do you want to use data to make a material and meaningful impact in a fast-moving company? Do you want to use your technical expertise to shape the future of our business for consumers and commercial partners? We're looking for a Lead Data Scientist to join our Analytics & Data Science team to drive the development of an innovative and market-leading pricing capability from concept through to deployment.

As a Lead Data Scientist, you will play a key role in building our Data Science capability at carwow working closely with stakeholders in Engineering, Analytics and the business. You will support our Analytics & Data Science function working directly to improve our proposition for users on both sides of our marketplace. We collect huge amounts of data and you will be using your expertise to unlock its power and accelerate the growth of the business.

You’ll be a key part of our Analytics & Data Science team, a centre of excellence guiding all areas of the business, working as a team to pool our vast knowledge and experience to deliver the biggest impact to carwow, its customers and its partners. carwow is a high-growth business and this role is a high-growth opportunity. This is a great opportunity to mentor other team members and share your experience and technical skills to maximise the value they generate.


Here’s how you’ll make a difference:

  • You'll build, test, deploy and continuously improve predictive solutions with a particular focus on developing our vehicle pricing and valuation models
  • You'll create explanatory models to help us understand the relationship between pricing and other commercial levers.
  • You’ll drive our approach for building the tools and processes needed that enable us to deliver machine learning solutions at scale
  • You'll work collaboratively with our stakeholders to build relationships, influence thinking, identify opportunities and deliver commercial value in ways we've never done before.
  • You'll continually learn and develop while playing a key role in coaching less experienced members, providing technical guidance and contributing to the wider data community at carwow.

We understand that no candidate will tick all of the boxes below so we’d encourage you to apply if you feel you're close to the brief but not an exact match.

Key skills:

  • Experience deploying and maintaining models via a Machine Learning Operations Platform such as Vertex AI, Sagemaker, MLFlow
  • Expert at SQL and Python including common data science packages (scikit-learn, Tensorflow, PyTorch etc)
  • Experience with time-series modeling techniques, forecasting and prediction

The FlexScore® is the result of a rigorous 2-step verification of a company’s flexibility

First we assess the flexibility options carwow provides and then we anonymously survey a statistically significant proportion of their employees to make sure carwow is as flexible as they say they are.
