Technology Research Engineer

Neo4j is the graph intelligence platform that transforms data into knowledge to power the next generation of intelligent applications and AI systems. It includes enterprise-ready knowledge graphs for accurate, explainable, and governed AI; the most comprehensive, trusted, and easy-to-deploy graph capabilities across any environment and data source; and an unmatched ecosystem trusted by 84 of the Fortune 100 and supported by the world’s largest graph community. Intelligence that works. Built to work everywhere and integrate with everything across every cloud for dynamic, personalized, and autonomous AI systems. 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.
Our mission in Neo4j Research is to create technology options through research so that our product engineering teams can continue to lead the market. We are computer scientists who enjoy building the technologies that will underpin our future graph intelligence platform. The Aurendil project embodies all of these: a new kind of database runtime that allows us to try new ways of executing queries on cloud hardware, that forges its own path parallel to, but separate from, the 40 years of relational database orthodoxy, and a team with an easy camaraderie.

We are expanding our UK-based team with talented post-doctoral researchers to take on the responsibility of realizing the Aurendil vision to build the next-generation of graph databases. The goal of the Aurendil project is to construct a radical new query language runtime for graph databases inspired by advances in programming language technologies. As such, we are building a cross-disciplinary team of post-doctoral researchers to design and implement the Aurendil prototype from the ground up.
Post-doctoral researchers joining the team will participate in the end-to-end development of a completely new database system architecture – from theoretical underpinnings, through to implementation and evaluation – and the dissemination of results to Neo4j product teams and the academic research community.
We are especially interested to hear from candidates with backgrounds in systems research – such as query languages, databases, compilers, parallel computing, distributed systems, or and hardware acceleration.
The ideal candidates will have experience in one of these fields:
Query Language(s) and their implementation
Programming Language(s) and their implementation
Managed Runtimes and Virtual Machines – JVM or GraalVM
Database internals
As this is a Research role, the ideal candidate will have experience working in an academic or industrial research environment and bring a robust understanding of research practice. A strong background in designing and developing complex systems using languages like C++, Java, or Rust would be beneficial.
The role is based in London, UK and requires significant in-office presence. Neo4j can provide visa support for exceptional international applications.
Neo4j is, without question, the most popular graph intelligence platform in the world. Joining our team is an opportunity to shape the future of data and analytics. Neo4j is one of the fastest-scaling technology companies in this industry. It recently surpassed $200M in annual recurring revenue (ARR), doubling its ARR over the past three years.

• Raised the biggest funding round in database history ($325M Series F). Backed by world-class investors like Eurazeo, GV (formerly Google Ventures), and Inovia Capital, Neo4j has raised over $600M in funding and is currently valued at over $2Bn. This puts Neo4j among the most well-funded database companies in history.
• Examples include Boston Scientific , BT Group , Caterpillar , Cisco , Comcast , Department for Education UK , eBay , NBC News , Novo Nordisk , Worldline , and others .
• Co-founder and CEO Emil Eifrem has built an amazing culture that prides itself on relationships, inclusiveness, innovation, and customer success.
• Massive enterprises and individual developers/data scientists love Neo4j. A strong sense of community and ecosystem is built around the platform.
• Research shows that members of underrepresented communities are less likely to apply for jobs when they don’t meet all the qualifications. At Neo4j, we are committed to building awareness and helping to improve these issues.

Neo4j is a Silicon Valley company with a Swedish soul. We foster collaboration and each of us is empowered to contribute and put our innovative stamp on projects.
