About Autotrader
You’ve probably heard of Autotrader, but do you know what we’re all about?
We’re the UK’s leading automotive marketplace, a heritage brand, and a tech darling of the stock market. We bring together vehicle buyers and sellers to give them real choices. Cars may be what we're best known for but we’re also the place for pretty much everything else on wheels, from e-bikes to caravans.
In the automotive world, change is a constant, that’s why we take our job of untangling the complex car-buying journey very seriously.
At our core, we’re all about people. We go our own way while embracing diversity and celebrating our differences. We dedicate ourselves to the idea that we work better together.
Autotrader is a beautiful, surprising and vibrant place to work. We might not be for everyone, but we could be perfect for you.
About the role
We're looking for Principal Software Engineers to help us build a technology platform for more than just the needs of Autotrader.co.uk.
Utilising our public-facing web services and additional external data sources means that we'll be able to power businesses across the automotive industry.
Spring Boot, Apache Solr, Cloud SQL and Apache Kafka power our platform and process millions of events per day. As a team, our software developers are responsible for ensuring service availability and responsiveness continue to improve. They work on systems that handle thousands of requests per second, with sub-100 millisecond response times, servicing requests from over 50 client applications.
Our tech community value collaboration and teamwork. Interactions such as pairing, code reviews and regular stand-ups mean our software developers stay connected. Our principal engineers play a visible and vital role, are comfortable talking about system design and architecture, and know how to get the best out of our teams and our technology platforms. We actively encourage AI-assisted workflows. Whether it's using GitHub Copilot to eliminate boilerplate or LLMs to bounce ideas around, we give you the tools to move faster and focus on the hard engineering problems.
You might assume that our name, "Autotrader," means you need to be a car enthusiast to work here. But that's not the case. We're looking for people who are passionate about their work and thrive in a collaborative environment.

Knowledge of server-side frameworks such as Spring

We’re offering a salary of £60,000 – £80,000, plus an additional 10% of your salary awarded to you in shares each year. These awarded shares will become yours in yearly instalments over the next three years, and you can choose to either sell them or keep them as shares. And you'll receive 28 days holiday, plus bank holidays and comprehensive private medical cover.
That’s not all. You'll be enrolled in our pension scheme, where our standard contributions are 7% and employee contributions are 5%. We also have comprehensive private medical cover, enhanced family leave provisions, a car salary sacrifice scheme, share-save options, and much more.
We always want to give you the support you need and help prioritise your wellbeing, that’s why we provide access to 24/7 online GP and dentist, as well as specialist support for assisted fertility, gender dysphoria, menopause, period care plans and lots more.
On top of all that, our hybrid model, Connected Working, combines the best of both worlds – office and home working. You'll spend a minimum of 3 days a week in the office with your team, focused on collaboration and connection.
Additionally, we have our remote-first periods at set times during summer and winter. During these periods, you can work remotely anywhere in the UK and from certain locations abroad.
