• Lead complex architectural and technical decisions across the application and provide technical direction and guidance to the software engineering team.
• Design resilient cloud-native services, data flows, integration boundaries, and capacity improvements while preserving approved functionality and external interfaces.
• Evaluate and prototype proposed technologies and framework upgrades, assessing security, accessibility, performance, migration, licensing, and operational impacts before changes are recommended for approval.
• Provide technical leadership across the application stack, including Node.js/TypeScript, React, relational databases, cloud infrastructure, and associated integrations.
• Partner with software engineering, DevOps, data, UX, QA, and security personnel to ensure technical solutions are cohesive and support overall product and program objectives.
• Guide engineering teams in addressing complex production issues, architectural faults, performance concerns, and technical debt.
• Serve as incident commander for major production outages and data-integrity events, coordinating technical response, restoration, root-cause analysis, and remediation.
