Senior Product Designer - Contract (Climate Tech) | 6-Month Contract, Strong Potential to Convert

Our client is a dynamic, fast-growing Series B climate tech company looking for a Senior Product Designer for a 6-month contract with strong potential to convert or extend. They help homes go solar and add battery backup, then connect those batteries together so they can support the power grid - all in the pursuit of a cleaner, more reliable energy future.

You would take the lead on the experience design of the company's growth channels - the entire customer journey from their website through checkout. This is a high-impact, high-visibility role: you'd be the dedicated designer shaping how homeowners discover the brand, build trust in it, and decide to go solar + battery.

Translating research and journey maps (with their experience & strategy team) into UX workflows and screens
Their Figma design system and component libraries
Prototyping to explore interaction patterns and pressure-test ideas
Production-ready handoff and build review with product and engineering
Performance analysis and content strategy alongside growth and marketing

What you bring:

Experience designing to optimize acquisition/checkout funnels for high-consideration / high-ticket products or services (e.g. financial products, insurance, vehicle leasing, or similar)
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

Advanced proficiency in Figma, with the ability to build out production-ready prototypes and design libraries

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, Lottie Files, or After Effects
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
