The posting

ABOUT THE ROLE

This is a founding-level role at a seed-stage B2B SaaS startup in the pricing intelligence space. You will own the entire frontend design system, component library, and UI coherence layer across a product that ships fast with both human engineers and AI coding agents. This role is the sole bar-raiser for frontend quality and UX standards across the company.

WHAT YOU'LL DO

- Define and maintain the design token system, component library, and frontend patterns that keep every shipped interface feeling like one cohesive product.

- Enforce frontend standards so that agent-written and human-written pull requests land consistently by default, using React Query, React Hook Form, and Zod.

- Own frontend tooling and quality, including Biome configuration, Playwright end-to-end coverage, and frontend performance.

- Translate design intent into component abstractions and lint rules to preserve coherence at scale.

- Build and iterate on conversational and AI-native interface patterns, including streaming responses and generative views.

- Integrate AI coding tools into the frontend workflow to accelerate delivery without sacrificing polish.

- Contribute to constrained UI surfaces such as chat-based or CLI-style interfaces where applicable.

WHAT WE'RE LOOKING FOR

- 5 or more years building and shipping polished product interfaces, with a strong portfolio demonstrating that quality.

- Deep expertise in React, strict TypeScript, and Tailwind CSS, with hands-on experience with component primitives such as shadcn/ui and Radix UI.

- Prior ownership of a design system or component library in production, demonstrated through a public repo, portfolio, or detailed walkthrough.

- Experience defining and enforcing frontend patterns across a team, including with AI-assisted coding tools such as Claude Code or Cursor.

- A hands-on design/UX engineer mindset, not a product designer role.

- Familiarity with animation and UI state transitions (e.g., Framer Motion) to enhance perceived speed and polish is a strong plus.

- Experience building conversational interfaces or chatbots for B2B users is a plus.

- Experience with constrained UI spaces such as Slack Block Kit or Microsoft Teams Adaptive Cards is a plus.

- Authorized to work in the United States without visa sponsorship.

COMPENSATION & BENEFITS

Base salary range: $180,000 to $220,000 USD annually. Equity participation is expected at this founding-team level. No visa sponsorship is available.

LOCATION

On-site in San Francisco, California, five days per week. Candidates must be based in San Francisco or willing and able to relocate.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
