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
- Curiosity and rigor in understanding how systems behave under stress, failure, and scale
- As a Senior Engineer on this team, you will work deep in Temporal’s distributed systems core—designing and implementing replication protocols, correctness mechanisms, and scalability features such as multi-cell namespaces and protocols that allow a single namespace to span multiple clusters and split or merge dynamically based on workload demands.
- Experience designing or maintaining replication protocols or data-plane infrastructure
- Experience with multi-cluster or multi-region architectures

Responsibilities
- Design and implement core components of Temporal’s OSS replication stack
- Build and evolve replication protocols that power:
- High Availability namespaces

- 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
