Principal Engineer – Stablecoin

Role Overview

• Develops the engineering approach for the entire program/portfolio solution and works with Architecture, to develop/analyze/deliver the implementation of technical enablers
• Leads the planning, definition, and design of the complex features which span multiple teams and explore solution alternatives
• Leads the technical oversight for teams in solution development including design reviews and code within own domain
• Defines the technology tool stack for the solution within ranged of internally approved and supported technologies
• Ensures that the Stablecoin design and engineering approach for complex features are consistent with the larger payments ecosystem
• Defines the technology tool stack for the solution and evaluate and adapt new testing tool/framework/practices for team(s)
• Enables team(s)/applications with Continuous Integration/Continuous Development (CI/CD) capabilities and engages with other technical stakeholders pertaining to efficient functioning of CI-CD pipeline
• Guides and influences team(s) on design and best practices for high code performance –e.g. pairing, code reviews
• Lead the design and development of secure, scalable financial blockchain applications, with a focus on stablecoin issuance, lifecycle management, and settlement use cases
• Define end-to-end blockchain architectures leveraging deep expertise in Web3 protocols, distributed ledger technology (DLT), and decentralized system design
• Design, develop, and maintain production-grade smart contracts using languages such as Solidity, Rust, or equivalent, aligned with banking-grade controls
• Implement and extend token standards (e.g., ERC‑20, ERC‑721, ERC‑1155) and integrate with DeFi primitives and protocols where applicable

Requirements
