- Collaborate with product managers and stakeholders to understand user needs and translate them into design solutions.
- Partner with full-stack engineers to ensure design fidelity in production implementations.
- Establish and enforce design standards, visual patterns, and best practices.
- Prepare detailed design handoffs with clear specifications, redlines, and interaction documentation.
- Lead user research initiatives and usability testing to validate design decisions.
- Review production implementations against designs to ensure consistency and quality.
- Stay current with UX trends and design tools to continuously improve our design practice.
- Document design patterns, component usage, and guidelines for the product team.
