ADHD can make daily life challenging, but accessing effective support shouldn't be. At Inflow, we're making ADHD care accessible through our comprehensive app that combines expert-led learning with practical tools and community support. We help people understand and work with their ADHD through bite-sized learning modules, guided journaling tools, live co-working sessions, and a supportive community. Since launching in April 2021, we've become the #1 ADHD management app, helping tens of thousands of people thrive with ADHD—and we're just getting started.

We are a fiercely ambitious team that thinks through everything from first principles and values logic over experience. In order to move fast, we learn fast. We believe in learning by doing, so we jump straight in. We say things as they are and believe success is driven by honesty.

About The Role

We're seeking a Lead Product Designer to drive user acquisition, engagement, and retention through exceptional product experiences. With 5+ years of B2C mobile design expertise, you'll blend deep user empathy with data-driven optimization to scale our impact.

As a key member of our Product team, you'll shape every touchpoint of the user journey—from first impression to long-term engagement. You'll partner with Product, Engineering, Marketing, and Data Science teams to identify opportunities, run experiments, and deliver meaningful improvements that help more people benefit from our product.

You'll lead the entire design process, from discovery and ideation to solution design, user research, high-fidelity execution, and Design System management. Balancing iterative experimentation with bold innovation, you'll optimize key growth levers while maintaining a cohesive product experience.

Responsibilities

• Drive end-to-end design ownership across the user journey, from research and ideation through high-fidelity implementation and continuous optimization
• Design and optimize key user experiences across acquisition, onboarding, activation, and retention to achieve ambitious growth metrics
• Lead user research initiatives to uncover deep behavioral insights, pain points, and opportunities that inform product strategy
• Develop and validate design hypotheses through A/B testing, leveraging behavioral psychology and quantitative data to maximize impact
• Partner with cross-functional teams across Product, Engineering and Marketing to identify opportunities, influence roadmap decisions, and ensure high-quality implementation
• Balance rapid experimentation with thoughtful, scalable solutions—knowing when to iterate quickly vs. invest in deeper exploration
• Evolve our Design System to maintain consistency while enabling rapid experimentation and growth
