Senior Protocol Engineer to build the core chain architecture behind institutional settlement infrastructure. Hands-on consensus, node infrastructure, distributed systems, and cross-chain design. Rust or Go. 5+ years engineering, 3+ in blockchain protocol work.
Global Settlement is building institutional-grade blockchain settlement infrastructure connecting traditional banking to digital markets across stablecoins, commodities, FX, and real-world assets (RWAs). The global reach of SWIFT, rebuilt for real-time, regulated digital asset settlement.
Small team, early stage, and you'd be building the chain itself.
This is protocol engineering, not application development. You'll own node infrastructure, consensus mechanisms, cross-chain systems, and settlement protocol design.
Smart contract work is part of the job. It isn't the center of it. If your experience is primarily Solidity, this isn't the right fit.
Design, build, and operate blockchain node infrastructure and settlement protocol architecture
Implement and tune consensus mechanisms (BFT, PoS, PoA) for enterprise throughput and deterministic finality
Architect cross-chain communication and bridging for multi-network settlement
Drive security, scalability, and reliability across all chain-level systems
Lead research on L1/L2 architectures, emerging protocols, and settlement patterns
Write the RFCs and architecture decision records engineering builds against
Mentor engineers and set infrastructure standards through code review
5+ years software engineering, 3+ years in blockchain or protocol infrastructure
Deep hands-on experience with consensus algorithms, node operations, and distributed systems design
Strong Rust or Go. Java, Solidity, or Python a plus
Production experience with Ethereum, Cosmos, Hyperledger, Canton, or comparable L1/L2 networks
Command of cryptographic primitives, key management, and on-chain security
Cloud infrastructure (AWS, GCP, Azure) and containerization (Docker, Kubernetes)
Shipped protocol infrastructure to production, not just smart contracts
Nice to have: stablecoin, CBDC, or RWA tokenization systems; cross-chain and interoperability protocols; financial services, payments, or regulated settlement background; digital asset compliance and regulatory requirements
Architect settlement infrastructure for sovereign and enterprise clients. Ground floor, real ownership, decisions that outlast you. Blockchain infrastructure, traditional finance, and regulation actually meeting.
