About the role

What you'll do

  • Build technically sophisticated, production-quality interfaces in React and TypeScript, with a high bar for craft.
  • Design rich visualizations and interactions that make complex AI systems, data, and workflows intuitive.

  • Prototype, iterate, and ship new experiences quickly, moving fluidly between engineering, design, and product.
  • Own the design system and frontend foundations, raising the bar for how the product looks and feels.

  • Comfortable working directly with customers and turning their feedback into better product experiences.
  • Able to operate fluidly across engineering, product, and design, owning outcomes without unnecessary handoffs.

Our Core Values

  • Customer Obsession - We start with the customer and work backwards. We aim to earn trust through consistent delivery, thoughtful listening, and by obsessing over customers.
  • Intellectual Honesty - We operate with high trust and low ego. Ideas matter more than titles, and we communicate openly and directly while assuming good intent, even in strong disagreement.
  • Bias for Action - We set high standards and move quickly to meet them. We prefer building and learning with customers over debating in the abstract, and we iterate based on real feedback.
  • Extreme Ownership - We take responsibility for outcomes, not just tasks. Ownership means seeing problems through to completion and ensuring solutions truly work in practice.

Benefits and perks

  • Competitive salary plus meaningful equity package
  • Comprehensive medical benefits and generous PTO
  • Flexible work arrangements
  • Direct impact on company direction and technical decisions
  • High ownership and the opportunity to make a career-defining impact
