• Develop storage layers, execution engines, transaction pools, gossip protocols, and state-machine replication.
• Implement, harden, and extend consensus algorithms for safety, liveness, and performance.
• Profile CPU, memory, I/O, and network stacks and optimize bottlenecks.
• Integrate cryptographic primitives including hashing, Merkle proofs, digital signatures, encryption, key exchange, and proof systems.
• Design peer discovery, NAT traversal, connection pooling, load balancing, congestion control, TLS, and multiplexed transports.

Requirements

• 2+ years building blockchain distributed systems and consensus engines.
• Expert proficiency in Rust and other low-level languages.
• Deep understanding of PBFT, HotStuff, and Tendermint consensus protocols.
• Strong cryptography fundamentals, including hashing, Merkle trees, multisignatures, and elliptic-curve cryptography.
• Solid TCP, UDP, QUIC, peer discovery, and NAT traversal experience.
• Experience with key-value stores such as RocksDB and MDBX.
• Authorization to work in the United States.
