Senior Software Engineer

Our Mission

Carwow Group is driven by a passion for getting people into cars. But not just any car, the right car. That’s why we are building the go-to destination for car-changing. Designed to reach drivers everywhere with our trail‑blazing portfolio of personality rich automotive brands;
Carwow, Auto Express, evo, Driving Electric and Car Buyer.

What started as a simple reviews site, is now one of the largest online car-changing destinations in Europe - over 10m customers have used Carwow to help them buy and sell cars since its inception. Last year we grew over 50% with nearly £3bn worth of cars bought on site, while £1.8bn of cars were listed for sale through our Sell My Car service.

In 2024 we went big and acquired Autovia, doubling our audience overnight. Together we now have one of the biggest You Tube channels in the world with over 1.1 billion annual views, sell 1.2 million print copies of our magazines and have an annual web content reach over 350million.

As a team our mission is to create a technology driven company where we are empowered to use our skills to solve difficult problems and scale the product.

To achieve this, we are looking to hire software developers that are passionate about developing simple solutions for complex problems. Successful candidates will work with our team in a full-stack position.

Our tech stack is primarily Ruby on Rails using Postgre

SQL, all hosted on Heroku. We use Terraform to manage our infrastructure and encourage teams to be involved in how we deploy and run our code in Production.

You’ll be supported by one of our Engineering Managers who are there to help you with your career progression and ensure that the team you are on are working as well as they can - continuously improving!

We have a career progression framework that means you know what is expected of you and how you can progress through our career ladder and your EM will work with you to make sure you are happy, fulfilled, and doing the best work you can be doing.

Senior engineers at Carwow work on cross‑functional product teams of product managers, engineers, designers and data analysts. You will work closely with a Product Manager and a Tech Lead on deciding what features to build for customers, break down and build features with the team, review code, mentor engineers, ensure operational excellence, and share knowledge broadly across the engineering organisation.

• We love solving real‑world problems!
• We work quickly, releasing code into production multiple times daily. You’ll see your code go live continuously.
• You’d be part of a growing team building a platform that will help define the future of car buying.
