Senior Blockchain Engineer

This role is IN PERSON at our office in Miami Florida. Do not apply if you cannot accommodate this.

Global Settlement () is building the future of digital settlement—an institutional-grade blockchain network designed to connect traditional banking and digital markets through stable coins, commodities, FX, and RWAs. Think of the global settlement reach of SWIFT, rebuilt for real-time, regulated digital asset transactions.

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

We’re adding a Senior Blockchain Developer 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 with blockchain node infrastructure, consensus mechanisms, and system design

• 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.

• 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

• 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

• 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

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.

• 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!
