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 Role

Join our dynamic Cypher team at Neo4j, where we are at the forefront of optimizing the core codebase that receives query strings and transforms them into efficient, logically sound execution plans. This role delves deep into the heart of the database, determining the most rapid and effective means of retrieving queried data from the underlying stores and indexes of the property graph model.

Responsibilities

As a Cypher Software Engineer, you will not only enhance and optimize the query planner but also contribute to the development of comprehensive features that elevate the capabilities of the Cypher language and the Neo4j database. Your impact will extend across the entire codebase, from the parser to the storage files and indexes. Success in this role requires the ability to think abstractly, discuss the pros and cons of different options, and anticipate edge cases in a design.

What You'll Bring

• Experience with performance-driven development, e.g., profiling, benchmarking, and optimizing code
• Familiarity with Agile development processes (TDD, kanban/scrum, pair programming)
• Knowledge of or willingness to learn Scala
• A desire to learn.

Nice To Also Have

• Experience programming in Scala and/or Java
• Understanding or previous experience with database design and implementation
• Interest or experience in developing compilers
• A strong foundation in algorithm design and analysis
• Interest in exploratory learning and transferring academic research into production-grade products
• 5+ years of experience developing high-quality, highly scalable production-level software

We don’t expect you to have experience across all these areas. We have a mix of different skills in our team. Many of our teams are spread over two or more locations, so you should be comfortable working as part of a distributed team.
