We’re working at significant scale – our service-oriented API Platform is handling billions of requests per month and growing quickly. You’ll be joining an enthusiastic team who enjoy what they do.

We know typing is not the bottleneck, so there are plenty of other things going on:

However, we’re not perfect and not afraid to say so. We recognise we have problems which need solving and a long way to go on our journey of continuous improvement.


About You

You care about software; you have a passion for what you do which you can clearly convey by your actions. You like to pick the right tool for the task at hand. You believe software development involves a lot more than just writing code. You aim to understand how your code runs in production. You see it as your remit to really understand our domain so we can all deliver as much value to the business as possible. To you, quality (both internal and external) really matters. These are things we really care about.

The Development Team

We’re strong advocates of Test Driven Development, and we want you to be too. We think that it represents such a different mindset that we would only consider you for a senior position if you have significant working experience with TDD. If you do, great! We want to know more. How do you do TDD? How have you used TDD on a recent project? What problems have you faced? The more the better!

We value outcomes over output. We follow Lean principles, building services based on measured impact rather than long lists of features. We use techniques such as Impact Mapping and User Story Mapping to ensure we deliver value at each step of the development process.

Technology you'll get to use

Our production systems run in a multi-cloud environment using various languages, primarily C#, Python and Node.js. We have a distributed data architecture with Apache Kafka at the heart. We are moving towards Linux and a cloud-native style architecture using technologies such as AWS Fargate and cloud functions. We’d be interested in you if you’re from any background as long as you have a keen understanding of good development practices. We have a strong DevOps culture and like to use externally managed services to allow us to focus on what makes our products great. We expect you to be proficient in more than one technology stack. Here are some technologies we currently use:
