• Experience building a new product or MVP from scratch in a small, agile team.

• Strong problem-solving skills, ownership mindset, and ability to thrive in a fast-moving environment.

• Empathy for users and ability to translate complex workflows into simple, intuitive interfaces.

• Collaborative spirit — you enjoy working closely with design and backend peers to deliver end-to-end value.
