Description
About Neo4j
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 it’s 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. Learn more at neo4j.com and follow us on LinkedIn.
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 Teams
You will be joining the ReleaseOps team - a multi-functional team that covers wide areas related to building, testing, and delivering code. However, initially, you will also be onboarded by the Build Systems team - a newly formed virtual group with a mission to improve the build infrastructure used by over 100 engineers across Neo4j. As this team consists of experienced developers who usually work in other teams, the interaction will only be temporary, and the ReleaseOps team is the long-term home of you and your work.
The Code
Our build system is currently based on Maven and supports a large repository using both Java and Scala. We face unique technical challenges around incremental builds, IDE integrations (especially with IntelliJ), and reliable packaging.
The Role
We’re looking for a Build Systems Engineer to take ownership of Neo4j’s build system and drive its evolution. This role offers the opportunity to go beyond maintenance, bringing fresh ideas and long-term solutions to how we build software at scale. You will be active in a highly collaborative environment with a big impact on day-to-day engineering productivity. You will work closely with the broader engineering organization to identify pain points, provide tooling improvements, and maintain a fast, reliable developer workflow.
