Blockchain Engineer

Senior Blockchain Engineer to own the settlement path of an institutional L1: transaction lifecycle, finality, and recovery for stablecoin, CBDC, and tokenized-asset payments. Hands-on node infrastructure, consensus, and distributed systems. Rust or Go. 5+ years engineering, 3+ in blockchain protocol work.

• 5+ years of software engineering, with 3+ years in blockchain protocol or node infrastructure. Production-grade blockchain experience beyond smart contracts is required. \n

• Deep hands-on experience with blockchain node infrastructure, consensus algorithms (BFT, PoS, PoA variants), and distributed systems design. \n

• Rust and/or Go experience, and the flexibility to switch stacks as the roadmap moves. \n

• Production experience with Ethereum, Hyperledger, Canton, or comparable L1/L2 networks. Full L1 node build-out and management of significant on-chain volume is the strongest signal.

You own the core settlement path of GSX Chain end to end: transaction lifecycle, finality guarantees, and the failure modes that only surface when money is stuck. This is blockchain infrastructure engineering on a payments chain. You will be in the node, consensus, and settlement-protocol code daily, making settlement provably correct under real institutional load.

\n

Time split: roughly 80% coding, 10% strategy and coordination with the team, 10% documentation.

What You’ll Do

\n \n

• Design, build, and operate the settlement path across the network, from transaction submission through deterministic finality. \n

• Harden consensus and recovery behavior under partial failure: network partitions, validator faults, stalled or replayed transactions, and reorg edge cases. \n

• Build the reconciliation and audit surface institutional clients verify settlement against. \n

• Own the incident path for chain-level settlement faults: detection, runbooks, root cause, and the fix. \n

• Instrument settlement latency, throughput, and correctness so the team sees problems before clients do. \n

• Contribute to cross-chain and bridging design where settlement spans networks, and write the RFCs and architecture decision records those changes build against. \n

• Work directly with protocol, ledger, banking-integration, and infrastructure engineers to ship testnet and mainnet milestones. \n

Global Settlement (globalsettlement.com) is building institutional-grade blockchain settlement infrastructure that bridges traditional banking and digital markets through stablecoins, commodities, FX, and real-world assets (RWAs). Think the global settlement reach of SWIFT, rebuilt for real-time, regulated digital asset transactions.
