  • Build the runtime engine: Design, implement and evolve core components of the Hazelcast runtime, including cluster services, distributed data structures and execution engines.
  • Work on distributed systems problems: Contribute to mechanisms for partitioning, replication, coordination and recovery in a distributed cluster.
  • Develop production systems: Write clean, well-tested Java code for long-running clustered systems that must remain reliable, observable and predictable in production.
  • Contribute to architecture: Collaborate with experienced engineers and architects to shape the design and evolution of the platform’s core runtime.
  • Raise the Engineering Bar: Participate in design discussions, code reviews and mentoring to maintain the high standards of the Core team.

Must have

  • Strong proficiency in Java and the JVM ecosystem
  • Experience building backend platforms or complex systems
  • Solid understanding of concurrency and multithreaded programming
  • Experience designing reliable system components and APIs
  • Ability to debug and reason about complex production systems
