About carwow

Buying or selling a car shouldn’t be difficult! That’s why here at carwow we are on a mission to change the way people buy, sell or use a car by creating the world’s best online car marketplace.

We're not all petrolheads - just a highly driven (excuse the pun) scale-up with over 350 carwowers in the UK, Germany, Spain and Portugal.

Since starting our journey in 2011, we’ve grown to become one of the most trusted comparison sites with over 12 million users and a Trustpilot rating of 4.7. We are also very proud to be backed by some of Europe’s most respected technology, marketplace and automotive investors.

Working here

At carwow, we aim to create a culture where our team can thrive no matter where or how they work. With hybrid working (1-2 days in the office although more if you like), and a healthy home office budget of £500, we are also open to looking at alternative working patterns to ensure carwowers can work in a way that works best for them.

We’re also a curious bunch and benefit from a number of different training opportunities. We are big on celebrating successes, working collaboratively and have found lots of ways to stay connected as a team both virtually and in person.

With a team of over 25 different nationalities, we know a diverse and inclusive workforce creates a more innovative company. We have work to do to get us where we’d like to be, but are working hard to get there and have a number of key DE&I initiatives underway.

So, if you always aim to WOW through everything you do (check out more info about our values here), we’d love you to join us on our journey.
