About This Role

We are hiring 2–3 Senior to Staff AI Frontend Engineers to work at the intersection of product design and frontend engineering. You are an engineer first, with exceptional design sensibility that elevates everything you build. You will define and implement the look and feel of AI-native workflows, ensuring complex enterprise tools feel as intuitive as the best consumer apps.

The product includes a real-time, WebRTC-powered companion agent that follows users across their screen, generative dashboards that visualize complex enterprise context graphs, agentic chat that operates the web application directly, and a new UI paradigm built around generative AI.

You will ship at AI speeds, work directly with a tight founding team, and help define the future of frontend SDLC. This role is based in the San Francisco office four days a week, with Wednesdays flexible.

What You’ll Own

  • Architect scalable frontend systems: design reusable component libraries, establish patterns for state management and API integration, optimize bundle sizes, and ensure the platform performs well at scale.
  • Own and ship primary user-facing features end to end, from React components through API integration to production polish.
  • Bridge AI capabilities with elegant user experiences by partnering with product and backend engineers to expose powerful functionality while hiding technical complexity.
  • Build complex frontend systems, including real-time WebRTC streaming for the companion agent, generative dashboards, and agentic chat that operates the product itself.
  • Use AI tools to rapidly prototype design concepts in code, bridging gaps between teams with working demos instead of static mockups.
  • Help define how the team scales code review and SDLC with agents that encode your architectural thinking.

Requirements

  • 6+ years of frontend experience at Senior to Staff level
  • Mastery of React, Next.js, TypeScript, and Tailwind
  • Ability to ship multiple features per day using AI tooling
  • High agency; former founder or comparable experience
  • Engineer first, with strong design instincts
  • Comfortable speaking with customers and sales, and shaping the product through action
  • Must be able to start immediately
  • A top degree, top startup experience (e.g., Sierra or Decagon), or another strong signal (e.g., patents or olympiads)
