Job description

Distributed Systems Engineer

We are looking for a Distributed Systems Engineer to design and operate the consensus, sharding, and replication layer of our globally distributed key-value store.

Roles and Responsibilities:
- Design and implement consensus protocols (Raft / Paxos) for strong-consistency replication
- Build and tune horizontal sharding, leader election, and failover paths
- Implement gRPC-based service-to-service communication with backpressure and circuit breakers
- Profile and optimize p99 latency across multi-region clusters; tune kernel networking + io_uring paths
- Author runbooks + chaos-engineering scenarios for partition / brownout / split-brain events
- Work with SREs on tracing, metrics, and incident response for distributed-state bugs

Required Skills:
Go, Rust, Raft, Paxos, gRPC, Protocol Buffers, Kubernetes, etcd, ZooKeeper, Linux kernel networking, distributed consensus, sharding, replication, chaos engineering, OpenTelemetry, perf, eBPF

Nice to have:
Formal methods (TLA+, Coq), CRDT, Spanner-style TrueTime, Fly.io / Cloudflare / Tigris experience
