What we’re looking for

We’re hiring a Senior Product Designer to lead UX for our AI-driven weather platform. As our first dedicated designer, you’ll define the design approach and ship intuitive interfaces for time-critical, expert workflows. You’ll partner daily with software engineers, research scientists, and go-to-market teams to turn complex functionality into simple, reliable tools that experts trust.

• Leverage analytics tools (e.g. user behavior tracking) to inform design decisions and measure impact

• Create and validate design concepts through user flows, personas, experience maps, wireframes, and interactive prototypes

• Develop and maintain a modular Figma design system, including documentation and usage guidelines, to ensure consistency

• Collaborate closely with engineers to ensure accurate and high-quality design implementation and resolve design/development trade-offs

• Craft clear, concise microcopy, including navigation labels, error states, and tooltips to support usability and tone consistency

• Communicate design rationale and present work to various stakeholders

• Stay current on UX/UI trends, tools, and best practices

Need-to-have

• 7+ years designing B2B, data-rich technical products; first/solo design hire or founding designer experience preferred

• Strong portfolio showcasing end-to-end design work, with emphasis on usability, visual design excellence, and measurable outcomes

• Experience instrumenting PostHog (or equivalent), defining an event taxonomy, building funnels/cohorts, and using insights to inform design while respecting user privacy.

• Advanced skills in Figma (prototyping, component libraries) and familiarity with other design/wireframing tools

• Hands-on experience with AI-assisted design tools and the ability to prompt, evaluate, and refine outputs into production-ready designs

• Strong understanding of responsive design, accessibility standards, and design systems

• Excellent collaboration skills and proven ability to work in agile, cross-functional teams

• Strong written and verbal communication skills in English, with confidence in presenting to diverse stakeholders

Nice-to-have

• Basic front-end development knowledge (TypeScript, React & Tailwind)

• Experience designing for complex or data-rich applications
