• You have experience of working with and creating JSON based REST APIs
• You're keen to work in a start-up environment
• You have excellent communication and collaboration skills
• You are a passionate technologist, keep up to date with the latest innovations and learn new things
• You have solid knowledge of software engineering principles, Agile practices, CI/CD and ideally have experience within a cloud environment (AWS preferred)
• Experience of interfacing with database products / languages; Neo4J or other graph database would be ideal
• You are degree educated, having achieved a minimum 2.1 from a top tier university

What's in it for you:
