We are So Energy, a fast-growing 100% renewable energy supplier in the UK. We’ve recently joined forces with ESB Energy to become the UK’s next big green energy supplier.

Our growing company of So Energists are a diverse group with a few important things in common, we're honest, ambitious, inquisitive and we're all passionate about building a more sustainable future.

The role

We have a heterogeneous tech stack including Kotlin, Ruby on Rails & Vue. We are converting our existing platform to a microservices architecture using Kotlin, Kubernetes and Google Cloud with the objective being a robust, performant, scalable and maintainable system that goes far beyond just our website.

We need someone who has a clear understanding of software engineering practices and agile development. Someone who has experience with different technologies and is able to quickly learn and adapt to new ones. Someone who can help in technical decisions but that genuinely enjoys constructive technical debates.

The successful candidate must be comfortable working alone, or as part of a team, and will help the team in converting legacy scripts, mechanisms and services into more maintainable microservices following development best practices & developing proofs of concept for projects of an RnD nature.
