• Strong senior-level experience shipping production web products.
• Strong frontend ability with React and TypeScript or an equivalent modern web stack.
• Ability to design and ship APIs, backend logic, and data flows.
• Strong product sense to notice awkward flows, weak defaults, and unnecessary complexity and improve them.
• Good judgment about scope, iteration, and technical trade-offs.
• Clear communication and comfort working across engineering, product, and design.
• AI-native working style, using AI tools as part of daily implementation and problem solving.

Strong Plus:

• Experience with AI-powered product experiences such as chat, search, recommendations, workflows, or agent-like systems.
• Experience with Python, Node.js, or both on the backend.
• Experience owning product areas with limited oversight.
• Strong feel for performance, accessibility, and production quality in complex web applications.

• Build and ship user-facing product features across frontend and backend boundaries.

• Work comfortably in UI, application logic, APIs, and data flows rather than stopping at team boundaries.
• Partner closely with product and design while still being able to move when the spec is incomplete.
• Improve usability, clarity, performance, and reliability, not just feature completeness.
• Instrument what you ship so we can learn from production behavior and iterate quickly.
• Use AI tools daily to move faster and help improve internal workflows, tooling, and engineering leverage.
• Keep the bar high on code quality, testing, and ownership after launch.
