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:

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.

As our Build Systems Engineer, you will:

Own and evolve our Maven-based build system for a large JVM-based repository

Improve speed, reliability, and maintainability across both local and CI/CD build environments

Collaborate closely with developers to identify bottlenecks, pain points, and opportunities for improvement

Introduce and enforce best practices around dependency management, versioning, packaging, and licensing

Contribute to better IDE experiences and development workflows, especially in IntelliJ

Help shape architectural decisions related to build tooling, and lead the design of new build features

Take a service-minded approach, supporting other engineers in building faster and more efficiently

What You'll Bring:

5+ years of experience in software engineering with a focus on build systems or developer tooling

Hands-on experience with JVM build tools such as Maven, Gradle, or Bazel

Experience working with large repositories and complex dependency structures

Software development experience in Java or Scala.

Familiarity with build performance tuning, incremental compilation, and CI optimization

Nice to have:

Experience with Scala compiler behavior and Maven integration

Familiarity with IntelliJ or Eclipse plugin/tooling ecosystems

Knowledge of software packaging pipelines and license/header enforcement

Contributions to open-source build tools or plugin ecosystems

We encourage you to apply even if you don’t have experience across all of these areas, since the team will have a mix of different skills.
