Blockchain Engineer

Join our Infrastructure & Platform team to architect and deploy highly reliable, scalable blockchain services with lightning-fast performance. You'll lead the development of mission-critical core infrastructure that powers our products.

What you'll do

• Develop storage layers, execution engines, transaction pools, gossip protocols and state-machine replication to deliver high-throughput, low-latency performance.

• Implement, harden, and extend consensus algorithms to guarantee safety, liveness and high performance under real-world network conditions.

• Profile CPU, memory, I/O, and network stacks, identify bottlenecks and push performance limits.

• Integrate diverse cryptographic primitives including hash functions, Merkle proofs, digital signatures, encryption schemes, key-exchange protocols and proof systems.

• Design and implement reliable peer discovery, NAT traversal, connection pooling, load balancing, congestion control, encrypted networking (TLS), and multiplexed transports (e.g. TCP, UDP, QUIC).

What you bring

• 2+ years building blockchain-based distributed systems and consensus engines.

• Expert proficiency in C++, Rust, Zig, or other low-level languages.

• Deep understanding of consensus protocols (e.g. PBFT, HotStuff, Tendermint).

• Strong cryptography fundamentals: hashing, Merkle trees, multisignatures, elliptic-curve cryptography.

• Solid networking experience: TCP/UDP, QUIC, peer discovery, NAT traversal.

• Hands-on experience with key-value store databases for efficient state storage and high-throughput access (e.g. RocksDB, MDBX).
