📋 Description

• Design, build, and ship full-stack features in their customer web app and growth surfaces. • Collaborate with product and revenue leadership to ideate, run, and analyze experiments (funnels, pricing/packaging, referral loops, lifecycle nudges, onboarding, and conversion optimizations). • Build and refine product flows that help families make confident, informed decisions. • Instrument analytics and event tracking to ensure clear, causal measurement of impact. • Contribute to a fast feedback loop: quick prototypes → data-informed iteration → polished releases. • Uphold reliability, accessibility, performance, and security across the stack.

🎯 Requirements

🏖️ Benefits

• Meaningful mission—your work directly supports families during one of life's hardest moments. • High impact and ownership—tight collaboration with leadership on product & growth strategy. • A small, talented team that moves quickly, values craftsmanship, and avoids unnecessary process.
