📝 Enhancement Note: This role is explicitly for a Principal Product Designer, indicating a senior individual contributor position that requires not only expert design craft but also leadership in setting design direction and mentoring junior team members. The emphasis on AI and modern workflows suggests a forward-thinking design team looking to optimize its processes.

📈 Primary Responsibilities

• Lead human-centered design across the entire customer journey, from initial research and user flows to microcopy, edge cases, and defining the ultimate standard of "good" user experience.

• Execute the full design lifecycle: translate research findings into actionable insights, create sketches and prototypes (utilizing AI-assisted tools where beneficial), conduct rigorous design reviews, produce detailed specifications for engineering, and remain involved through product launch.

• Actively contribute to roadmap and strategy discussions with Product leadership, bringing a strong point of view and vision for the customer experience.

• Collaborate effectively with Engineering, Product, and Marketing teams to ensure the product presents a unified and consistent brand identity.
