Descripción de la vacante

Launch Legends seeks a senior Rust engineer to Harden and extend block production, validation and finality components for its live blockchain project Autheo. You will own P2P paths, work on state storage, and profile hotspots with CI benchmarks to detect regressions.

Collaborate with SRE on validator reliability, runbooks, and observability, while applying deep networking knowledge (libp2p/QUIC) and advanced Rust skills.

Formación

• Production Rust: ownership, lifetimes, async (Tokio) and debugged concurrency.
• Hands-on work in a real blockchain or distributed-consensus codebase.
• Networking depth in libp2p, QUIC or gossip protocols.
• Linux performance tooling and a CI pipeline that builds and tests Rust.

Responsabilidades

• Harden and extend Rust block production, validation and finality components.
• Work on state storage, sync, pruning and snapshot tooling.
• Own Rust P2P paths: discovery, gossip, backpressure and faulty-peer handling.
• Profile node hot paths and add CI benchmarks for performance regressions.
• Work with SRE on validator and RPC reliability, runbooks and observability.
