Senior Blockchain Engineer, Settlement

As a Senior Blockchain Engineer at Global Settlement, you own the settlement path of an institutional L1: transaction lifecycle, finality, and recovery for stablecoin, CBDC, and tokenized asset payments. You work hands-on with node infrastructure, consensus, and distributed systems, reporting to the core protocol team building settlement infrastructure that bridges traditional banking and digital markets.

What you'll do

• 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.

What you bring

• 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.

What we offer

• In-person role in Miami, Florida, with the option to start remote and relocate within 60 days.
• Full-time position with ground-floor opportunity to architect settlement infrastructure used by sovereign and enterprise clients.
