You're fluent enough across APIs, data, and cloud to ship a feature end-to-end without waiting on anyone.

## Description

You'll spend about 70% of your time building and 30% leading. You'll guide a team of 2-4 engineers, and serve as a primary partner to client engineering leaders., * Deep expertise in React, TypeScript, and Next.js, including state management, rendering strategies, and application architecture.
\n

 * Shipped streaming or conversational UI in production, including tool-calling patterns and structured model output.
\n

 * Experience building or consuming MCP servers, or a comparable tool-integration layer for LLMs.
\n

 * Hands-on experience building or scaling a design system and component library.
\n

 * Mastery of HTML, CSS, and responsive design, with working knowledge of WCAG accessibility standards.
\n

 * A track record of measurable front-end performance work.
\n

 * Solid back-end skills in Node.js, Python, or a comparable ecosystem. You can design and build the APIs your UI needs.
\n

 * API experience across REST and/or GraphQL, plus working fluency with PostgreSQL and NoSQL stores.
\n

 * Working knowledge of cloud platforms, CI/CD, and Docker.
\n

 * Comfort working in other frameworks, such as Angular or Vue, when a client's stack calls for it.
