• Creates ideas on designing complex technology and solution development approaches
• 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 a range of internally approved and supported technologies
• Explores state-of-the-art technologies to improve development efficiencies, quality of test/QA coverage, and release management
• Leads and is responsible for the end-to-end test strategy/creation/adherence, and the integration between teams for a program/portfolio solution
• Improve the experience for our developers, making it easier to deliver industry-leading solutions, while managing work efficiently and with the right controls
• Advance our technology platforms through innovation
• Reduce risk and improve quality across our technology portfolio by aligning to a single enterprise architecture strategy and delivering governance that enables consistency, integration, and automation
• Define and drive the UI platform architecture for AI-powered and agent-assisted developer experiences
• Build scalable frontend frameworks, component systems, and design patterns to support dynamic, AI-driven workflows
• Design interactive, conversational, and workflow-centric interfaces that integrate with LLMs and autonomous agents
• Partner with AI/ML and platform teams to integrate LLMs, APIs, and agent orchestration layers into cohesive user experiences
• Define standards for prompt-driven UX, contextual interfaces, and adaptive UI behavior based on model outputs
• Ensure secure, role-aware, and governed experiences aligned with enterprise IAM/SSO
• Drive adoption by establishing frontend standards, usability benchmarks, and developer experience best practices
