🚀 Role Summary

• Drive critical user acquisition and retention metrics for a digital wellness iOS application through innovative product design solutions.

• Lead the design strategy for paywall optimization and onboarding flows, directly impacting Lifetime Value (LTV) per download and trial conversion rates.

• Leverage cutting-edge AI design tools for rapid prototyping, A/B testing of potential features, and the creation of Vibe Marketing campaigns for social media engagement.

• Collaborate closely with a founder-led product team to translate user needs and business objectives into intuitive and engaging user experiences.

• This is an execution-focused role, emphasizing a "get your hands dirty" approach to product development and iterative design improvements.

📝 Enhancement Note: This role is positioned as a hands-on Product Designer with a direct impact on key business metrics (LTV, trial conversion). The emphasis on "not a strategic role" suggests a focus on tactical execution, rapid iteration, and close collaboration with a product-focused founder, rather than high-level strategic planning. The use of AI design tools and Vibe Marketing indicates a forward-thinking approach to feature validation and marketing.

📈 Primary Responsibilities

• Design and iterate on user interfaces and user experiences for the Lemio iOS application, focusing on improving LTV per download through strategic design interventions.

• Develop and A/B test different paywall configurations and onboarding sequences to maximize trial start rates and user commitment.

• Utilize AI design tools to rapidly generate mockups, prototypes, and visual assets for user testing and marketing campaign development.

• Conduct user research and analyze user feedback to inform design decisions and identify areas for product enhancement.

• Collaborate with the founding team to define product roadmaps and prioritize design initiatives based on impact and feasibility.

• Implement Vibe Marketing campaigns using AI-generated creatives to test feature concepts and engage potential users on social media platforms.

• Maintain a user-centric approach, ensuring all design decisions are grounded in user needs, behavioral insights, and key performance indicators (KPIs).

📝 Enhancement Note: The responsibilities clearly delineate a focus on conversion rate optimization (CRO) for both acquisition (trial start rate) and retention (LTV). The mention of "Vibe Marketing" and AI tools suggests a modern approach to user engagement and rapid experimentation, which is crucial for a fast-paced startup environment.
