About Keystone and LYRIQ

The core platform is a permissioned, BFT-replicated distributed ledger written primarily in Rust, with a signed append-only transaction log, hierarchical account trees, programmable transfer and access rules, and hardware-backed key custody.
As Senior Rust Engineer, Distributed Ledger, you will work close to the metal on consensus, cryptography, state storage, and correctness engineering. You will also build and support the gRPC services, SDKs, operating evidence, and integration patterns that Keystone customers and bank engineering teams use to connect to the platform.
