• Design scalable APIs and data models that support new transaction types, products, and regulatory requirements without increasing operational burden.
• Write well-tested, production-grade code that other critical systems depend on.
• Monitor and communicate the health of ledger and payment systems, proactively identify issues, and participate in incident response and remediation.
• Mentor teammates to ensure new functionality is correct, auditable, and production-ready.
• Participate in on-call rotations as needed.
