Why Turso Uses Rust Here
Latency spikes kill throughput. Limbo replaces synchronous POSIX file locks with a fully asynchronous state-machine B-Tree pager over Linux io_uring, verified continuously against corruption via deterministic fault-injection simulation.
We are hiring a Staff Rust Database Engineer (Limbo SQLite Rewrite & io_uring) (Worldwide Remote) at $175,000 to $235,000 USD. Implement SQLite bytecode VDBE instructions in safe Rust, expand deterministic simulation fuzzing seeds, and reduce page-cache lock contention.
Day-to-Day Engineering Scope
- Architect and benchmark core crates built around io_uring and LSM-Tree and Raft and Wasmtime and no_std.
- 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 (io_uring, LSM-Tree, Raft).
- Comfort reading assembly output (`cargo asm`), kernel tracepoints, or wire protocol captures when abstractions leak.
- Verified package: $175,000 to $235,000 USD base salary plus competitive equity and global remote healthcare.
