MyTutor | Senior Software Engineer (Java) | London, UK | Full-Time | Remote (UK, EU) or On-site | https://www.mytutor.co.uk

MyTutor is the UK’s leading online platform for one-to-one learning, and we're on a mission to improve the educational outcomes of millions of young people. We’re building a future where access to high quality learning is stress-free for those who can afford it, and funded for those who can't.

We’re looking for senior software engineers across our Product Engineering team to help us create a scalable components/apps/microservices based architecture. Being curious about and comfortable with complex code transition is essential to this role, as is being reasonably language agnostic. An interest in Javascript towards the front end or Java towards the back end wouldn’t be out of place though!

Our current tech stack is a Java/SQL backend hosted in AWS, with Spring Boot and Kafka also in play. Our front end is transitioning to React.js. We operate in multi-disciplinary agile squads, each owning their own part of the feature set. We've invested a lot of effort in making sure our squads can operate nimbly and own their own destiny and have a modern CI/CD pipeline.
