About carwow

We’re on a mission to change the way people buy, sell or use a car by creating the world’s best online car marketplace. Since starting our journey in 2011, we’ve grown to become one of the most trusted comparison sites with over 12 million active users and an ‘excellent’ Trustpilot rating of 4.7.

carwow is backed by some of Europe’s most respected technology, marketplace and automotive investors, with $55 million Series D funding secured in December 2021. 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 Senior Data Scientist to join our Commercial Analytics & Data Science team to help us create innovative predictive solutions and see them through to deployment.

As a Senior Data Scientist supporting our Commercial function, your work will directly 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 company.

You’ll be part of our Analytics & Data Science team, a centre of excellence supporting all areas of the business, working together 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. To be successful requires an enterprising spirit, self-discipline and the ability to be straight-talking yet constructive.

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 play a key part in building the tools and processes needed for us to deliver machine learning solutions at scale
  • You'll work collaboratively with our stakeholders to build trusting relationships, influence thinking, identify opportunities, and deliver commercial value in ways we've never done before.
  • You'll continually develop your own skills while also coaching less experienced members, providing technical support and contributing to the wider data community at carwow.


We are committed to creating an inclusive workplace that promotes and values diversity. We welcome applications from candidates of all genders, races and neurological backgrounds. 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:

  • Expert at SQL and Python
  • Experience creating accurate predictive solutions using packages such as Scikit-learn, Statsmodels, Tensorflow and PyTorch
  • Experience with time-series modelling techniques
  • Experience deploying and maintaining models via a Machine Learning Operations Platform such as Sagemaker, Vertex AI, MLFlow, or Databricks
  • Natural communicator with the ability to influence and build trust by articulating complex data science concepts to a non-technical audience
  • Experience building accurate pricing/valuation models
  • Strong track record of delivering impactful and commercially relevant solutions
  • Deep interest and aptitude in prediction, maintaining an awareness of emerging tools and techniques
  • Able to deliver solutions iteratively and effectively in a fast-paced environment

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. Our assessment is based on the six key elements of flexibility: location, hours, autonomy, benefits, role modelling and work-life balance.

We ask the hard questions so you don’t have to.
