Senior Blockchain Engineer

This role is IN PERSON at our office in Miami, Florida.

Senior Blockchain Developer

Company Description

Global Settlement (globalsettlement.com) 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.

Role Description

We're seeking a Senior Blockchain Developer to join our blockchain infrastructure team. This is a full-time position.

Who We're Looking For

We're adding a 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.

Experience Needed

• Experience with blockchain node infrastructure, consensus mechanisms, and system design

Key Responsibilities

• Design and architect blockchain solutions that meet business and technical requirements.
• Lead the development and implementation of blockchain-based applications and services.
• Partner with cross-functional teams to integrate blockchain technology into Global Settlement's payment platform.
• Ensure the security, scalability, and performance of blockchain solutions.
• Conduct research and stay current with the latest advancements in blockchain technology.
• Offer technical guidance and mentorship to development teams.
• Build and maintain documentation for blockchain architectures and implementations.
• Identify and mitigate potential risks tied to blockchain solutions.
• Take part in code reviews and uphold best practices and coding standards.

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 finality
• Architect cross-chain communication and bridging systems for multi-network interoperability
• Work with smart contract and application teams to deliver integrated blockchain solutions
• Drive security, scalability, and reliability across all chain-level systems
• 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

What You Bring

• 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

• Experience with stablecoin systems, CBDC infrastructure, or RWA tokenization
• Familiarity with cross-chain protocols
• Background in financial services, payments, or regulated settlement systems
• Understanding of regulatory and compliance requirements in digital asset markets

Note: 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.

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
• Join Global Settlement and help build the future of digital payments through innovative blockchain solutions!

Join us at Global Settlement and help build the future of digital payments through institutional-grade blockchain infrastructure.
