Responsibilities

We are representing a confidential software development organization seeking a Staff Software Developer to join their core libraries team in London. In this role, you will:

  • Design and maintain foundational libraries for core programming language primitives used by hundreds of thousands of developers worldwide
  • Develop deep expertise in specific domains of computer science and software engineering
  • Serve on the design committee that shapes critical API decisions
  • Contribute to the creation of standard tooling, specifications, and language features
  • Research and implement solutions to complex technical challenges, from Unicode standards to timezone handling and JIT optimization

What We're Looking For

Our client is seeking a senior-level engineer with:

  • Strong JVM development experience, including deep familiarity with Java standard library implementation details
  • Demonstrated understanding of complex technical domains

  • Experience in performance engineering or API design
  • Comfort working with low-level technical specifications and standards
  • An analytical mindset and willingness to iterate on documentation and design
