You're a conversion‑focused designer who lives at the intersection of mobile product design, growth, and experimentation. You have a track record of shipping real paywalls and funnels that move business metrics, not just portfolios
You have:
5-8+ years designing consumer mobile experiences, with a substantial portion spent on subscription or purchase flows (e.g., paywalls, onboarding, upgrade/upsell, win‑back, account limits)
Experience either:
At a mobile app studio / product team owning monetization UX, or
At an agency/consultancy repeatedly designing and optimizing paywalls and funnels for multiple apps
Comfort defining hypotheses, success metrics, and test plans (e.g., CVR, trial start rate, activation, LTV)
Experience using analytics and experimentation tools to interpret results and iterate quickly
Ability to balance conversion gains with long‑term user trust and platform guidelines
Excellent interaction and visual design chops for small screens and high‑stakes surfaces (like paywalls and purchase flows)
Strong UX writing instincts for concise, value‑focused copy and pricing messaging
Proficiency in modern design tools (e.g. Figma) and comfort translating designs into no‑code builder configurations
Confidence leading workshops, design reviews, and strategy sessions with customers and prospects
Ability to present options, pros/cons, and trade‑offs to both designers and non‑design stakeholders (founders, PMs, marketers)
Great written communication for async collaboration in a remote team
You're energized by our mission to help developers make more money
You work iteratively and ship value quickly rather than waiting for perfection
You have an ownership mentality: You see broken or unclear experiences and feel compelled to improve them
You're comfortable working in a fully remote, distributed team and collaborating across time zones
Competitive equity in a fast-growing, Series C startup backed by top-tier investors, including Y Combinator
10-year window to exercise vested equity options
A fully remote environment designed around autonomy and flexibility
4-5 weeks of flexible time off annually
