Company

Temporal is an open source programming model that can simplify code, make applications more reliable, and help developers focus on the important things like delivering features faster.

What you will do

• Design and implement core components of Temporal’s OSS replication stack.
• Build and evolve replication protocols that power High Availability namespaces, cross-cluster and cross-region replication, and migration between Temporal clusters.
• Develop scalability and reliability features such as multi-cell namespaces.
• Reason deeply about consistency models, ordering guarantees, and failure recovery in replicated systems.
• Own complex changes end-to-end, from design through implementation, testing, and rollout in OSS and cloud environments.
• Participate in on-call and incident response related to replication and core system behavior.

Requirements

• Strong experience building distributed systems with a focus on replication, consistency, and fault tolerance.
• Demonstrated ability to design and implement concurrent, correctness-critical systems.
• Hands-on experience debugging complex production issues involving race conditions, data consistency, or performance degradation.
• Proficiency writing production-quality concurrent code, preferably in Go (Java or similar systems languages also welcome).
• Solid understanding of distributed systems fundamentals (consensus, replication, sharding, backpressure, failure detection, etc.).
• Ability to take ownership of technically deep areas and drive improvements with minimal oversight.

Nice to have

• Experience designing or maintaining replication protocols or data-plane infrastructure.
