This role is in person at our office in Miami, Florida.
Global Settlement is building the future of digital settlement — an institutional-grade blockchain network designed to connect traditional banking and digital markets through stablecoins, commodities, FX, and RWAs. Think of the global settlement reach of SWIFT, rebuilt for real-time, regulated digital asset transactions.
We're adding a full-time Senior Blockchain Engineer to our blockchain infrastructure team. This is a hands-on engineering role centered on building and scaling our core chain architecture. You'll work directly on node infrastructure, consensus mechanisms, cross-chain systems, and protocol-level design alongside our application team.
This is primarily a blockchain infrastructure role. Smart contract development is part of the work, but the core focus is chain-level architecture, consensus, node operations, and cross-chain systems. If your experience is solely in smart contract development, this likely isn’t the right fit.
Design, build, and maintain blockchain node infrastructure and settlement protocol architecture
Implement and optimize consensus mechanisms (PoA, PoS, BFT variants) for enterprise-grade performance and finality
Architect cross-chain communication and bridging systems for multi-network interoperability
Partner with smart contract, application, and cross-functional teams to integrate blockchain technology into Global Settlement's payment platform
Drive security, scalability, and reliability across all chain-level systems
Identify and mitigate potential risks tied to blockchain solutions
Lead technical research on emerging protocols, L1/L2 architectures, and settlement patterns
Provide technical mentorship to developers across the engineering organization
Own documentation for blockchain architecture decisions, RFCs, and implementation standards
Participate in code reviews and set best practices for infrastructure development
5+ years of software engineering experience, including 3+ years focused on blockchain development
Deep hands-on experience with blockchain node infrastructure, consensus algorithms, and protocol-level system design
Strong proficiency in one or more of: Rust, Go, Solidity, Java, or Python
Working knowledge of blockchain platforms such as Ethereum, Cosmos, Hyperledger, or comparable L1/L2 networks
Solid grasp of cryptographic primitives, key management, and on-chain security practices
Experience with cloud infrastructure (AWS, Azure, or GCP) and containerization (Docker, Kubernetes)
A track record of shipping production blockchain infrastructure — not just smart contracts
Nice to have: stablecoin systems, CBDC infrastructure, or RWA tokenization; cross-chain protocols; a background in financial services, payments, or regulated settlement systems; an understanding of regulatory and compliance requirements in digital asset markets
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.
Join us at Global Settlement and help build the future of digital payments through institutional-grade blockchain infrastructure.
