THE ROLE Neo4j is the leader in graph analytics, and our cloud platform is at the heart of powering data-driven innovation for thousands of users worldwide. We are on the lookout for versatile Full-Stack Engineers to help us design and build exceptional features that lower the bar for users to perform graph analytics.
