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
Migration between Temporal clusters
Develop scalability and reliability features such as:
Multi-cell namespaces
Protocols enabling a single namespace to span multiple clusters
Dynamic split and merge of namespaces based on usage and capacity
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
Write clear design documents and code comments that explain protocol behavior, invariants, and tradeoffs
Collaborate closely with Cloud Enablement and other CGS teams to ensure OSS foundations support current and future cloud products
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

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
Curiosity and rigor in understanding how systems behave under stress, failure, and scale.
