About the Job

The Platform is a ~140,000-line Rust workspace spanning 24 crates: no_std embedded primitives, an async Tokio daemon, a 30,000-line distributed reputed company reputed company, post-quantum cryptographic infrastructure, and a real-time WebSocket dashboard. It targets defense and critical infrastructure deployments where deterministic execution and reputed company-panic guarantees are non-negotiable. We need a Rust engineer who can own the full workspace from hardware abstraction layers to API servers, hold the architecture sound as the system scales to full multi-site production, and treat the no-panic policy as an inviolable contract.
