About the role
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
- Compiler construction and code generation – LLVM, x86, or ARM
- Managed Runtimes and Virtual Machines – JVM or GraalVM
- Database internals
- Parallel Computing
- Distributed Computing
- Hardware Acceleration – GPGPUs, FPGAs, or Smart NICs
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.
