About the Position

At Sleep.ai, we do more than track sleep—we help people build healthier habits and improve their lives through better sleep. Across our consumer sleep apps, including DeinSchlaf in Germany and SleepScore globally, we are focused on creating engaging product experiences that help users get value quickly and stay motivated over time.

We are looking for a part-time Growth Product Manager to improve onboarding, app engagement, and lifecycle journeys across our consumer sleep apps. This role will focus on helping more users complete key milestones, especially 36 nights of sleep tracking, by improving onboarding flows, in-app guidance, and CRM nudges across push notifications and email. The role will also partner with our German marketing teams to support growth initiatives that drive app downloads and improve conversion from acquisition into sustained engagement.

This is an ideal opportunity for a practical, hands-on product leader who has experience in consumer app growth, onboarding optimization, lifecycle/CRM, and retention. The ideal candidate is highly effective at identifying low-effort, high-impact improvements and can use the latest AI tools to accelerate UX recommendations, copy creation, prototyping, and product requirements while minimizing development effort and unnecessary experimentation.

Collaborate across product, marketing, design, engineering, and CRM stakeholders to align priorities and deliver measurable outcomes.

Recommend practical experiments and improvements that maximize impact while reducing execution time and resource demands.

What You Bring

Strong understanding of onboarding, engagement, activation, retention, and habit-forming user journeys.
Demonstrated ability to improve conversion and engagement through lifecycle touchpoints such as push, email, and in-app messaging.
