Double Eleven Limited
🇬🇧 Middlesbrough

Senior C# /.NET Developer (UK)

We see ourselves as a new civilisation of people emerging to make the world of gaming better. We’re a different breed of games company - we do things our own way in our own style, not necessarily following what’s been done before.

Our people are at the heart of our evolution and we nurture them to be their best. Without them our vision would fail.

We strive to avoid crunch, overtime is optional and always paid, and we offer flexible working hours to allow you to enjoy a normal family life whilst still working on great gaming titles. Most recently, we helped to bring Minecraft Dungeons and Rust: Console Edition to millions of players around the world.

We’re growing rapidly and as a result we’re looking for a Senior C# / .NET Developer to join our studio in Middlesbrough (UK), home to the beautiful North Yorkshire coastline and countryside.

As a Senior C#/.NET Developer at Double Eleven, you’ll be responsible for working on our applications and systems that utilise C# / .Net, including updating existing code and writing new applications to assist in the development of our games.

You don’t need to come from the games industry to apply!

Initially you’ll work remotely due to the Covid-19 pandemic and when it’s safe for our team to return to the studio, you’ll set up camp at our HQ in Middlesbrough, UK. Currently we’re working effectively remotely and we continue to assess the Covid-19 situation, with the safety of our staff as our top priority. We’re still actively recruiting and onboarding new staff and will provide you with everything you need to join remotely.
