Job Description: Product Design Lead

Experience the full process: shape product-market fit and scale the business.
Collaborate closely with founders and management, learning from their experience in product development and international markets.
Tackle significant challenges in a global, diverse environment.
Work alongside industry leaders focused on delivering exceptional user experiences.
Use the latest technologies and bring your unique flair to the role.

Own and lead the user research practice, with emphasis on early, prototype-driven user testing.
Use AI-assisted prototyping to quickly explore ideas, validate assumptions, and identify risks before engineering commitment.
Transform ambiguous feedback into clear hypotheses, prototypes, and actionable learnings for product direction.

Define and evolve the design philosophy and principles, balancing speed vs. polish and AI-enabled workflows vs. traditional processes.
Ensure design decisions are evidence-based, grounded in feedback from real users.

Build, scale, and maintain a design system that encodes user insights and enables fast learning and iteration.
Champion modern tools and workflows—especially AI—that reduce the cycle time from idea → prototype → user feedback → decision.

Coach the design team to adopt prototype-first, research-led workflows.
Foster a culture where learning happens through experimentation, making, and iteration.
Stay hands-on: prototype, test flows with users, and unblock high-impact work as needed.

Collaborate closely with Product and Engineering to ensure learning velocity drives roadmap decisions.
Build shared understanding of users through prototypes, narratives, and clear synthesis.

Fluency in qualitative user research (concept testing, usability testing, workflow validation).
Strong leadership in product design with a prototype-first mindset—using early artifacts to test and learn.
Design systems thinking: ability to translate learnings into patterns, systems, and principles.
Hands-on experience with AI-assisted design/prototyping tools; curiosity to explore new approaches.
Collaborative leadership style: engage Product and Engineering in continuous learning.
Cross-platform experience: design for both web and desktop.
Bias to action: favor multiple iterations and steady release progress over perfection.
