Job Description

About Carwow

We’re Carwow. The car-changing experts for life-changing moments. Whether buying, selling, or (car) window shopping, we aim to give people total confidence in their choice.

We kicked off our journey as the ultimate matchmaker for car reviews, helping everyone pick their perfect ride. But we soon realised this wasn’t the destination - it was just the first leg. Why stop there when we could also help them get a great price?

So we decided we wanted to revolutionise selling cars, just like we did with buying them. That's when we introduced our game-changing 'sell my car' product.

Today, our dedicated team of over 350 experts across the UK, Germany, Spain and Portugal look after over 12 million active users (and an ‘excellent’ Trustpilot rating).

And we’ve got plenty left in the tank.

Working here

So, what does Carwow look like under the hood?

We’re always driving forward, and our people love what they do and love working together. Our goal is to empower our employees to discover their passions, create common ground, and take control of their careers with confidence.

We regularly fine-tune our hiring process to ensure fairness and all Carwowers receive comprehensive DE&I training. Our Diversity Committees, led by our fantastic employees, fuel internal education, help out our local communities, and champion initiatives for our customers.

We’re also Flexa100 nominated and aim to be the go-to place for changing cars. We’re proud to say we’ve got an impressive employee average engagement score of 8.5/10!

Bonding as a team is important to us - whether we're rocking the Carwow Olympics worldwide, playing drag bingo for Pride Month, taking part in beach clean-ups or rallying on the Padel court, there’s always something to bring us together.

Fancy a life-changing career from the car-changing pros? We’d love you to join us on our journey.

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.
