Senior Blockchain Engineer

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.

Role

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

Qualifications

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.
