Responsibilities

• Build acquisition and marketing surfaces in our Astro-based site, creating faster, more interactive, more personalized, and more fun experiences.
• Partner with Design to translate Figma, prototypes, and AI-generated explorations into production-grade motion and interaction.
• Own the motion and interaction primitives that evolve across marketing and eventually product.
• Build data-driven marketing pages that bring real campaign and cause data to life (per-cause hubs, per-campaign stories, per-vertical landing pages).
• Wire marketing surfaces into analytics and feature-flag systems (PostHog, LaunchDarkly).
• Collaborate with the 3rd-party Webflow team on cross-cutting work (analytics, tracking, SEO, technical decisions).
