About the RoleThis is a founding-level frontend role at a seed-stage B2B SaaS startup building an AI-native pricing intelligence platform. You'll own the entire frontend design system - tokens, component library, and interface patterns - ensuring everything shipped, whether by humans or AI coding agents, feels like one cohesive product. As the sole bar-raiser for frontend UX, your work directly shapes how enterprise customers experience pricing strategy and deal intelligence.
What You'll Do- Define and maintain the design token system, shadcn/ui-based component library, and Tailwind conventions across the full product suite.
- Enforce consistent frontend patterns using React Query, React Hook Form, and Zod so that agent-generated PRs land coherently by default.
- Audit and own frontend tooling and quality, including Biome configuration, Playwright E2E coverage, and frontend performance.
- Integrate brand guidelines and WCAG accessibility rules directly into the codebase and lint rules.
- Translate design intent into component abstractions and tooling guardrails that scale as the team and AI agents ship more UI.
- Work with AI coding tools (e.g., Cursor, Claude Code) as a first-class part of your daily workflow and help the team integrate them into frontend processes.
- Shape conversational and streaming UI patterns for the platform's AI-native interfaces.
What We're Looking For- 5+ years building polished, production product interfaces with a strong portfolio of shipped features.
- Proven primary ownership of a design system or component library in production (public repo or detailed walkthrough required).
- Deep expertise in React, strict TypeScript, Tailwind CSS, and component primitives such as shadcn/ui and Radix UI.
- Hands-on experience with AI coding tools in production workflows.
- Comfort being the sole frontend UX standard-setter across a fast-moving, small team.
- Nice to have: Experience with non-standard AI interfaces (streaming responses, generative views), conversational/chatbot UIs for B2B users, animation libraries like Framer Motion, or constrained UI environments such as Slack Block Kit or Teams Adaptive Cards.
- Must be authorized to work in the US - visa sponsorship is not available.
Compensation & BenefitsBase salary:
$180,000 - $220,000 USD annually. Equity participation expected at the founding team level. No visa sponsorship available.
