Senior Blockchain Developer

About Global Settlement Global Settlement ( globalsettlement.com ) is building the future of digital settlement — an institutional-grade blockchain network that bridges traditional banking and digital markets through stablecoins, commodities, FX, and RWAs. Think of the global settlement power of SWIFT, modernized for real-time, regulated digital asset transactions. The Role We're hiring a Senior Blockchain Developer for our blockchain infrastructure team. This is a hands-on, full-time engineering role focused on building and scaling our core chain architecture — node infrastructure, consensus mechanisms, cross-chain systems, and protocol-level design. 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. - Collaborate with smart contract and application teams to deliver integrated solutions. - Drive security, scalability, and reliability across all chain-level systems. - Lead technical research on emerging protocols and L1/L2 architectures. - Mentor developers, own architecture documentation and RFCs, and establish best practices through code reviews. What You Bring - 5+ years of software engineering experience, with 3+ years in blockchain development. - Deep hands-on experience with 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 platforms such as Ethereum, Cosmos, Hyperledger, or comparable L1/L2 networks. - Solid understanding of cryptographic primitives, key management, and on-chain security. - 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 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 — working at the intersection of blockchain infrastructure, traditional finance, and regulatory innovation.
