Motion & animation skills — able to bring designs to life with tools like After Effects and/or Lottie (animated paywalls, onboarding transitions and UI micro-interactions).
Basic knowledge of conversion-oriented copywriting.
Experience in subscription products across different niches (utilities, productivity, health&fitness, photo/video tools, AI consumer products).
Other requirements
Experience working in a fast-paced, entrepreneurial team environment.
Ability to respond quickly to changing priorities.
