UI/FrontEnd Engineering

We’re a fast-moving, top-tier VC-funded Silicon Valley startup building ambitious, user-facing products at the intersection of modern web applications and AI-powered systems. We’re looking for frontend engineers who thrive in ambiguity, move quickly, and care deeply about craft.

You’ll build polished, production-quality user experiences that users trust and love. You’ll work end-to-end—from early product ideas and design exploration to shipping and hardening UI in production—owning frontend architecture and raising the bar for quality across the product.

You’ll fit right in if you’ve worked at an early-stage startup before—or if you’ve always wanted to experience the intensity, ownership, and speed that comes with building from zero to one. We value initiative over process, learning over perfection, and collaboration over hierarchy.

Things change daily, and that’s part of the fun: you’ll wear multiple hats, iterate quickly, and help shape both the product and the engineering culture from the ground up.

• Build production-quality frontend products: design and implement high-quality user interfaces using React and modern TypeScript, with a focus on correctness, performance, accessibility, and long-term maintainability.
• Rapid iteration with ownership and bias for action: move quickly from idea to shipped UI, take autonomy in decision-making from day one, and operate comfortably in a fast-paced, evolving codebase; own frontend features from design through production.
• Operate with extreme leverage and build guardrails: aggressively use modern AI tools (e.g., Claude) to accelerate frontend development while owning correctness and quality; write meaningful unit, integration, and UI tests, maintain coverage, and document component and system behavior—especially for AI-assisted code.
• Frontend architecture & state management: design scalable component systems, manage complex client-side state, and make principled tradeoffs across UX, performance, reliability, and developer experience.
• API-driven frontend development: integrate cleanly with backend APIs (REST and/or GraphQL), handle auth flows, pagination, loading and error states, and collaborate with backend engineers to shape pragmatic, stable contracts.
• Collaborate with product and design: work closely with product managers and designers to define UX flows, refine requirements, and turn ambiguous problems into secure, compliant, and delightful user experiences.
• Raise the frontend bar: mentor teammates through code reviews, shared patterns, design discussions, and documentation that improves frontend quality and consistency across the product.

• Craft mindset: you care deeply about UI correctness, performance, accessibility, and polish—and you notice the details others miss.
• Bias to action: you ship early, iterate often, and don’t wait for perfect clarity to get started.
• React expertise: you’ve built and maintained real-world React applications with modern state management, hooks, and component patterns.
• Testing instincts: you believe tests and clear component boundaries are guardrails, not overhead.
• Product sense: you think beyond pixels and understand how frontend decisions impact usability, trust, and business outcomes.
• AI-practical: you’re comfortable using AI tools to speed up frontend work while staying accountable for quality and maintainability.
• Startup mindset: you’re comfortable with ambiguity, changing requirements, and owning outcomes without hand-holding.

• Experience with modern frontend tooling (Vite, Next.js, Remix, etc.).
• Familiarity with frontend performance profiling and optimization.
• Accessibility experience (ARIA, screen readers, keyboard navigation).
• Experience designing or contributing to a component system or design system.
• Prior startup experience or meaningful open-source contributions.

• Bias to action: short feedback loops, fast iteration, reversible decisions.
• Quality without ceremony: tests, clear abstractions, and good defaults are table stakes.
• Written culture: design notes, component docs, and decision logs that scale with the team.
• High ownership: take on scope that excites (and stretches) you.

• You’ve shipped multiple user-facing features that users rely on daily.
• You’ve improved frontend reliability, performance, or UX in measurable ways.
• You’ve introduced patterns, components, or tests that raise the bar for the whole team.
• You’ve become a trusted partner to product and design.

• Be part of the core product and engineering team at an early-stage, well-funded AI startup
• Work directly with experienced founders and top-tier investors
• Build products where frontend quality and user experience truly matter
• High ownership, high impact, and rapid growth opportunities
• Competitive compensation, meaningful equity, benefits, and long-term upside
