• Extensive UI/UX experience with a strong portfolio that demonstrates both craft and measurable outcomes
• Experience generating and interpreting quant data alongside qual data to inform design decisions
• Partnered closely with engineering teams to ensure high-quality execution and attention to detail
• A proven ability to articulate design decisions clearly and adapt feedback from research and data into actionable improvements
• A self-starter mindset with the ability to balance product excellence and business impact in a quickly-changing, iterative environment
• Advanced proficiency in Figma, with the ability to build out production-ready prototypes and design libraries
• Knowledge of web accessibility standards and best practices, ensuring our platforms are inclusive of all potential visitors
• Design systems experience, with the ability to maintain and update design libraries and components within Figma
• UI animation skills, leveraging tools such as Figma Motion, LottieFiles, or AfterEffects
• Illustration skills, with the ability to create custom UI illustrations or iconography
• Familiarity with tools that close the gap between design and engineering, such as Claude Code, Webflow, Cursor, or Framer
• Experience driving and facilitating user research or validation testing sessions
• Collaborated closely with content strategy, UX writing, or marketing teams
• Designed for chatbot experiences or AI-enabled customer workflows
• A background in climate tech, consumer tech, or home energy industries
