Blockchain Engineer

Global Settlement Network; Miami (FL); On-site; USD 120,000 - 240,000; Full time

Job summary

Global Settlement is building institutional-grade blockchain settlement infrastructure in Miami, focusing on core chain architecture, node infrastructure, consensus mechanisms, and cross-chain systems. This is a hands-on engineering role on production systems, not a research role, with daily work in node, consensus, and settlement‑protocol code.

You will design, implement, and optimize the core chain, drive RFCs and architectural decisions, and mentor engineers.

Qualifications

• 5+ years software engineering, with 3+ years blockchain development
• Hands-on experience with blockchain node infrastructure, consensus algorithms, and protocol-level design
• Proficiency in Rust, Go, Solidity, Java, or Python and ability to switch stacks as needed
• Production experience with Ethereum, Cosmos, Hyperledger, Canton, or similar L1/L2 networks
• Familiarity with cryptographic primitives, key management, and on-chain security
• Experience with cloud infrastructure (AWS, GCP, or Azure) and Docker/Kubernetes
• Startup mindset and ability to work autonomously, shipping robust infrastructure

Responsibilities

• Design, build, and maintain blockchain node infrastructure and settlement protocol architecture
• Implement and optimize consensus mechanisms for enterprise-grade performance and deterministic finality
• Architect cross-chain communication and bridging systems for multi-network interoperability
• Improve security, scalability, and reliability across all chain-level systems
• Debug and harden production systems, including edge cases and on-chain security
• Lead technical research on emerging protocols and translate findings into shipped code
• Collaborate with smart contract, application, and banking-integration teams
• Own RFCs and architecture decision records, mentoring engineers through reviews
• Role is hands-on with ~80% coding time, 10% strategizing, 10% documenting

Job description

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 (globalsettlement.com) 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.

• 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

Location

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

New hires may start remote with the expectation of relocating to Miami within 60 days of start date. Must be legally authorized to work in the United States.
