A signal privately tells Hazelcast you're interested. It is not a job application.
About the role
At Hazelcast, we build a high-performance real-time data platform used in mission-critical systems across industries such as finance, e-commerce and telecoms. Our platform enables applications to access and process data in milliseconds, powering use cases like fraud detection, real-time inventory tracking and dynamic pricing.
We’re looking for a senior Java software development engineer to join the Core team, the group responsible for the engine at the heart of the Hazelcast Platform. This distributed, Java-based system combines low-latency data storage, in-place compute and stream processing across clusters of machines.
This role is ideal for engineers who enjoy building core backend systems and working on the mechanics of distributed platforms, such as concurrency, coordination, data distribution and behaviour under load, failure and changing cluster topology. 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. You’re a strong Java engineer who enjoys building complex backend systems and understanding how they behave in production.
