Job Description

Senior Blockchain Engineer

Global Settlement · Miami, Florida (in person) · Full-time · Blockchain Infrastructure

Senior Blockchain Engineer to build and scale the core chain behind institutional settlement infrastructure: node infrastructure, consensus mechanisms, cross-chain systems, and protocol-level design. Hands-on engineering on production systems. Rust, Go, or comparable. 5+ years engineering, 3+ in blockchain.

The salary range for this role is $120,000 - $240,000 per year.

About Global Settlement

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.

The role

You build and scale the core chain architecture on our blockchain infrastructure team: node infrastructure, consensus mechanisms, cross-chain systems, and protocol-level design, working alongside our application team. This is a hands-on engineering role on production systems, not a research or advisory one. You will be in the node, consensus, and settlement-protocol code daily.

What you’ll do

• 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 deterministic finality.
• Architect cross-chain communication and bridging systems for multi-network interoperability.
• Drive security, scalability, and reliability across all chain-level systems, and identify and mitigate the risks they carry.
• Debug and harden production systems: consensus edge cases, node performance, and on-chain security.
• Lead technical research on emerging protocols, L1/L2 architectures, and settlement patterns, and translate it into shipped code.
• Collaborate with smart contract, application, and banking-integration teams to deliver integrated settlement solutions.
• Own the RFCs, architecture decision records, and implementation standards engineering builds against, and mentor engineers through code and design review.
• This role is a hands-on coding role with roughly 80% of your time spent coding, 10% of time spent strategizing and coordinating with team members, and 10% of your time spent documenting.

What you bring

• 5+ years of software engineering, with 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, and the flexibility to switch stacks as the roadmap moves.
• Production experience with Ethereum, Cosmos, Hyperledger, Canton, or comparable L1/L2 networks. A track record of shipping production blockchain infrastructure, not just smart contracts, 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 systems, CBDC infrastructure, or RWA tokenization.
• Cross-chain and interoperability protocols.
• Financial services, payments, or regulated settlement background.
• Digital asset compliance and regulatory requirements.

Note: This is a blockchain infrastructure role scoped to the core chain. The core focus is node infrastructure, consensus mechanisms, cross-chain systems, and protocol-level design. If your experience is solely in smart contract development or application backends without protocol-level work, this may not be the right fit.

Why join Global Settlement

• Ground-floor opportunity to architect settlement infrastructure used by sovereign and enterprise clients
• Direct impact on how digital assets move through the global financial system
• Work at the intersection of blockchain infrastructure, traditional finance, and regulatory innovation
