Fractional CRO (Retention Product Manager)

Dinarys GmbH is looking for a Fractional CRO (Retention Product Expert) to help improve user engagement, conversion, and retention for a digital health mobile application.

The product already has a broad set of features, including AI-powered capabilities, but users tend to drop off shortly after installation. We’re looking for a hands-on specialist who can analyze user behavior, identify where and why users drop off, build the right measurement framework, and systematically improve conversion and retention.

This is a fractional, hands-on role for someone who has actually built and optimized CRO/retention processes, analytics, dashboards, and experiments — not just provided strategic recommendations.

• Candidate Business Value

You will help the product build a systematic, data-driven approach to conversion and retention, identify the main reasons for user drop-off, and turn these insights into measurable product improvements.

Responsibilities:

• Analyze existing user behavior data and assess the quality, accuracy, and completeness of tracking.
• Define the key conversion, engagement, and retention metrics and establish a clear measurement framework.
• Build and maintain dashboards to track user behavior, conversion, retention, and trends over time.
• Identify key drop-off points and conversion/retention bottlenecks across the user journey.
• Develop and prioritize data-driven hypotheses for improving conversion and retention.
• Design and run experiments with the product and development team and measure their impact.
• Establish a repeatable CRO/retention optimization process based on continuous measurement and experimentation.
• Translate findings into clear product recommendations and actionable tasks for the team.

Requirements:

• Proven hands-on experience in CRO, conversion optimization, user engagement, or retention for digital products.
• Strong track record of improving conversion and/or retention, supported by specific examples and measurable results.
• Experience working with mobile apps and user funnels, including post-install user behavior.
• Strong experience with product analytics, user behavior tracking, and building custom dashboards and reports.
• Understanding of how to define, track, analyze, and forecast key product metrics over time.
• Experience developing and validating hypotheses through A/B tests or other product experiments.
• Ability to work hands-on with data and analytics rather than relying only on existing reports.
• Experience working with product and engineering teams to implement tracking, experiments, and product improvements.
• Strong analytical and structured thinking.
• English C1.

Nice to Have:

• Experience in ecommerce, digital health, or consumer mobile products.
• Experience working with custom-built platforms and setting up analytics/reporting from scratch.
• Experience with tools such as Amplitude, Mixpanel, GA4, Firebase, Appsflyer, or similar.
• Experience with AI-powered products.
• Background in Growth Product Management or Product Analytics.

Engagement:

• Fractional / part-time
• Approximately 1–2 days per week
• Remote
• Long-term collaboration based on product needs
• International digital health product
• Direct collaboration with the product and development team
