• Strong technical fluency and adaptability within modern design workflows, including experience working with code-based sources of truth and tools such as Claude Code, alongside decreasing reliance on traditional design-file workflows.
• Demonstrated ability to use AI tools throughout the design thinking process, including research synthesis, ideation, prototyping, and validation, while understanding where human judgment and expertise remain essential.
• Expert-level knowledge of qualitative and quantitative research methods, with the ability to turn customer insights and behavioral data into meaningful product decisions.
• Proven experience collaborating with product and engineering teams to influence strategy, align stakeholders, and drive measurable outcomes without formal management authority.
• Strong communication, problem-solving, strategic thinking, and collaboration skills, combined with a high degree of autonomy and ownership.
