- Engineering Craft: Take pride in writing clear, well-structured, and maintainable code, and care deeply about long-term quality over short-term fixes.
- Systems Thinking: Think beyond individual components, understanding how state, data, and UI architecture work together across a large application.
Product & User Empathy: Care about building interfaces that help users understand complex data quickly, and they make thoughtful tradeoffs in service of usability. - Ownership & Accountability: Take responsibility for outcomes, follow work through from design to production, and continuously improve what they ship.
- Collaboration & Communication: Communicate clearly, welcome feedback, and work effectively across engineering, design, and product to solve hard problems together.
Qualifications/Requirements:
