Why CoreWeave Uses Rust Here
Latency spikes kill throughput. CoreWeave accelerates massive GPU clusters connected with InfiniBand and RoCEv2 fabrics. Low jitter is paramount. The security dataplane must evaluate policy tokens, detect traffic anomalies, and enforce cryptographic boundaries without introducing latency penalties into active tensor exchanges. Every cycle counts. Rust combined with Linux eBPF and lock-free memory tables provides deterministic microsecond throughput.
We are hiring a Principal Distributed Systems Engineer (Security & Traffic Dataplane) (New York, NY / Sunnyvale, CA) at $227,000 to $303,000 USD. Architect four-nines availability microsecond authentication proxies, eBPF packet filters, and distributed token verification pipelines under multi-region load.
Day-to-Day Engineering Scope
- Architect and benchmark core crates built around Tokio and RDMA and eBPF and Tonic and Linux Kernel.
- Replace allocation-heavy paths with zero-copy buffers, arena allocators, or lock-free ring queues.
- Pair with upstream open-source maintainers and internal platform teams to ship fault-tolerant releases.
Technical Expectations & Pay
- Demonstrated mastery of Rust ownership, pinning, lifetimes, and concurrency primitives (Tokio, RDMA, eBPF).
- Comfort reading assembly output (`cargo asm`), kernel tracepoints, or wire protocol captures when abstractions leak.
- Verified package: $227,000 to $303,000 USD base salary plus competitive equity and global remote healthcare.
