Senior Product Designer

Inflow is a company focused on helping individuals access support for ADHD, recently acquired by Cerebral, a leading digital mental health provider in the US. They are seeking a Senior Product Designer to own the design process end-to-end and optimize user experiences across various growth surfaces, utilizing modern AI tools to enhance design velocity.

Responsibilities:

• Own end-to-end design across growth surfaces — from research and ideation through high-fidelity implementation and continuous optimization
• Design and optimize key growth surfaces. Funnels, onboarding, engagement, retention, referrals and more, across web and app
• Go from idea to working prototype fast using AI tools (Cursor, Claude Code, Codex, etc.) — sometimes close enough to ship
• Develop and validate design hypotheses through A/B testing and quantitative data
• Conduct user research to inform design decisions and uncover opportunities
• Balance rapid experimentation with thoughtful solutions, knowing when to iterate quickly vs. invest in deeper exploration

Requirements:

• 3+ years of B2C product design experience — consumer apps, e-commerce, or subscription products, with proven impact on business metrics
• You're particularly strong in at least one area that matters to us, whether that's conversion design, building with AI, compelling UX storytelling, or running experiments that move metrics
• Growth experience with hands-on work in at least two areas: CRO, onboarding, activation, monetization, retention, referrals, checkout, or AOV optimisation
• Already building with AI (Cursor, Claude Code, Codex, or similar) as a natural part of your design workflow
• Comfortable with A/B testing and data-informed design decisions — you don't need to be a data scientist, but you need to understand that experiments drive priorities in this role
• Strong portfolio demonstrating design process and measurable outcomes
• Good design instincts around user psychology and behavior
• Comfortable with ambiguity, fast pace, and working in a small team with real ownership
• Background in mental health or healthcare products
