Build context with engineering, product, and design, learn how dashboards and call logs connect to backend services, and ship a meaningful improvement. * 60 Days: Take end-to-end ownership of a core workflow in call health/LLM observability or reporting and analytics. Deliver production React, TypeScript, and Tailwind work with strong API integration, testing, and measurable improvements to performance, accessibility, or usability. * 90 Days: Become the primary frontend owner for your area. Establish reusable patterns in the design system and Storybook, improve how data-intensive and real-time interfaces scale, and help the team use agentic coding without compromising craft.
