The role

- Optimize bundle sizes and application performance as usage grows.

- Ship the main user-facing features end-to-end, from components through API integration to production polish.

- Partner with product and backend engineers to present powerful functionality in a simple, elegant interface.

- Build complex real-time and interactive frontend features, including streaming, dashboards and conversational interfaces.

- Prototype design ideas directly in code using AI tools, sharing working demos in place of static mockups.

- Contribute ideas for making the team's review and delivery processes faster through automation.

- High agency, shown through founder, founding engineer or significant ownership roles at a startup.

- Current awareness of AI tooling and the ability to explain how your own stack has changed recently.

- Comfort speaking with customers and sales to shape the product.

- Based in San Francisco or willing to relocate immediately.

Bonus points

- Prior founder or founding engineer experience.

- Real-time streaming or video pipeline experience.

- Voice AI product experience.
