• Strong understanding of experimentation, including A/B testing, hypothesis development, prioritization frameworks such as RICE, and data-driven product decision-making.
• Proven ability to work effectively with Product and Analytics teams and integrate design into broader product strategy.
• Excellent visual judgment, design taste, and attention to detail combined with strong analytical and problem-solving abilities.
• Strong leadership, communication, mentoring, and stakeholder management skills.
