Software Engineer - Cypher

Neo4j is the leader in Graph Database & Analytics, helping organizations uncover hidden patterns and relationships across billions of data connections deeply, easily, and quickly. Customers use Neo4j to gain a deeper understanding of their business and reveal new ways of solving their most pressing problems. Over 84% of Fortune 100 companies use Neo4j, along with a vibrant community of 250,000+ developers, data scientists, and architects across the globe.

At Neo4j, we’re proud to build the technology that powers breakthrough solutions for our customers. These solutions have helped NASA get to Mars two years earlier, broke the Panama Papers for the ICIJ, and are helping Transport for London to cut congestion by 10% and save $750M a year. Some of our other notable customers include Intuit, Lockheed Martin, Novartis, UBS, and Walmart.

Neo4j experienced rapid growth this year as organizations looking to deploy generative AI (GenAI) recognized graph databases as essential for improving its accuracy, transparency, and explainability. Growth was further fueled by enterprise demand for Neo4j’s cloud offering and partnerships with leading cloud hyperscalers and ecosystem leaders.

Our Vision: At Neo4j, we have always strived to help the world make sense of data. As business, society and knowledge become increasingly connected, our technology promotes innovation by helping organizations to find and understand data relationships. We created, drive and lead the graph database category, and we’re disrupting how organizations leverage their data to innovate and stay competitive.

The Team: Join our Cypher teams as a software engineer to develop and extend the Neo4j query language. Cypher is similar to SQL, but designed by us specifically for graph databases and for finding patterns in a graph. Working in the Cypher teams is technically very rewarding, working on solving complex problems on many different levels.

Responsibilities: We are recruiting for all levels of the Cypher stack, from parsing and semantic analysis to query planning, optimization and execution; as well as identity & access management and handling of procedure framework and database schema & administration. The development is done in Scala and Java, and there will be possibilities to work in areas ranging from language design to advanced algorithms, concurrent programming, and mastering the JVM internals. You will be working in an international environment with colleagues mainly in Sweden and the UK, but also elsewhere in Europe. The teams (5-7 engineers) are self-organised and set up their own ways of working, within the guidelines of the overall ways of working in Engineering. As an engineer, you have a lot of freedom in how you carry out the tasks ahead of you.

What you will bring:

• A Master of Science in Computer Science or similar experience
• Knowledge in Java or Scala (or a similar language)
• Experience of Databases
• Experience of secure development practices, and writing security sensitive code
• Familiarity with Agile development processes
• Strong analytical skills and a drive to solve complex, non-trivial problems requiring deep algorithmic thinking and first-principles reasoning

Nice to have:

• Neo4j experience
• Experience with algorithm design and analysis
• Understanding of hardware architecture
• Experience in compiler engineering
• Understanding of JVM internals
• Scala, or another functional language
• Experience with authentication/authorization systems including role based access control and OpenID Connect
• Experience with performance-driven development, e.g. profiling, benchmarking and optimizing code
• Interest in exploratory learning and transferring academic research into production grade products

Why Join Neo4j? Neo4j is, without question, the most popular graph database in the world. We have customers in every industry globally, and our products are a proven product/market fit. Joining our team is an opportunity to shape the future of data and analytics.
