You'll be working in a complex, fast-iteration environment, shaping a digital experience central to our path to product-market fit. This is a part-time contract (20–25 hours/week) for 3 months from October - December 2025, with flexible scheduling inside 9am -5pm PST as well as around key collaboration moments. There is also potential for contract renewal for 2 - 3 months in the first half of 2026.

• Interested in mission aligned climate and social impact work with schedule flexibility
• Seeking a project with portfolio worthy UX strategy and complexity

What you'll do:

• Own design for a critical digital experience in tight design–ship–learn cycles.

• Partner closely with product, engineering, and research to test and iterate quickly.
• Handle stakeholder conversations and keep work moving without heavy oversight.
• Prepare production-ready design files, specs, and assets for development handoff.
• Document design decisions and outcomes and maintain a clear trail of work for continuity after the contract period.
