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.
Global Settlement 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.
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.
Design, build, and operate the settlement path across the network, from transaction submission through deterministic finality
Harden consensus and recovery behavior under partial failure: network partitions, validator faults, stalled or replayed transactions, and reorg edge cases
Build the reconciliation and audit surface institutional clients verify settlement against
Own the incident path for chain-level settlement faults: detection, runbooks, root cause, and the fix
Instrument settlement latency, throughput, and correctness so the team sees problems before clients do
Contribute to cross-chain and bridging design where settlement spans networks, and write the RFCs and architecture decision records those changes build against
Work directly with protocol, ledger, banking-integration, and infrastructure engineers to ship testnet and mainnet milestones
This is a hands-on coding role: roughly 80% of your time coding, 10% strategizing and coordinating with the team, and 10% documenting
5+ years of software engineering, with 3+ years in blockchain protocol or node infrastructure. Production-grade blockchain experience beyond smart contracts is required.
Deep hands-on experience with blockchain node infrastructure, consensus algorithms (BFT, PoS, PoA variants), and distributed systems design
Rust and/or Go experience, and the flexibility to switch stacks as the roadmap moves
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.
Command of cryptographic primitives, key management, and on-chain security practices
Cloud infrastructure (AWS, GCP, or Azure) and containerization (Docker, Kubernetes)
Startup work ethic and heavy use of productivity and coding tools to multiply your own output and the team's. You can take a three-bullet brief and execute without hand-holding.
Nice to have: stablecoin, CBDC, or RWA tokenization settlement systems; cross-chain and interoperability protocols; banking, neobank, payments, or regulated settlement background; digital asset compliance and regulatory requirements
Note: this is a blockchain infrastructure role scoped to the settlement layer. The core focus is chain-level correctness, consensus behavior, node operations, and the settlement protocol. If your experience is solely in smart contract development or application backends without protocol-level work, this may not be the right fit.
Ground-floor opportunity to architect settlement infrastructure used by sovereign and enterprise clients, with direct impact on how digital assets move through the global financial system. You would be working at the intersection of blockchain infrastructure, traditional finance, and regulatory innovation.
This role is in person at our office in Miami, Florida. New hires may start remote with the expectation of relocating to Miami within 60 days of their start date. Must be legally authorized to work in the United States.
Join us at Global Settlement and help build the future of digital payments on institutional-grade blockchain infrastructure.
