Mindset & Approach

• Comfortable with ambiguity: You can make progress when the problem is unclear, the technology is evolving, or the path forward is undefined.
• Think by making: You use code and tangible artifacts to explore ideas, test possibilities, and communicate concepts.
• People‑first: You value direct user feedback and use it to challenge assumptions and improve solutions.
• Adaptable across fidelity levels: You’re comfortable building quick, disposable experiments as well as more robust prototypes for extended testing.
• Curious about emerging AI: You enjoy exploring new models and tools, testing their boundaries, and finding applications that create meaningful value for users.
