Description du poste

Posse is a dynamic app studio based in Paris, dedicated to creating innovative and scalable digital products. We thrive on creativity, collaboration, and data-driven decision-making to deliver meaningful user experiences. As we scale our flagship apps, we’re looking for a hands-on Product Growth Manager to drive product iteration, user insights, and revenue optimization.

Role Overview

We’re not looking for a Product Owner to manage a backlog — we’re looking for a builder . Someone scrappy, curious, and hands-on. You love rolling up your sleeves, shipping quick experiments, digging into numbers, and finding what works. You might have dabbled in no-code, launched side projects, or tested funnels on the fly.

You’ll operate on two complementary missions :

1. Scale Inshallah : our dating app : boost retention, conversion and monetization.

2. Build Dygest : our non-fiction book summary app : identify growth levers, test product-market fit, and find scalable value.

Key Responsibilities Iteration & Testing

• Design and execute A / B tests on features, flows, onboarding, paywalls, etc.
• Drive a test-and-learn culture and maximize the number and quality of experiments.
• Monitor and document test results and recommend rollouts.

Data-Driven Product Management

• Use analytics tools (Amplitude, Firebase) to make data-backed decisions.
• Synthesize user feedback, quantitative insights, and behavioral trends.
• Define a clear vision and roadmap aligned with business priorities.
• Balance quick wins and long-term product evolution.
• Collaborate with founders on product direction and prioritization.

Cross-functional Execution

• Work hand-in-hand with engineers, designers, marketers, and CRM managers.
• Ensure features are shipped fast and meet both UX and business goals.
• Partner with the UA team to optimize acquisition and conversion funnels.

Bonus Responsibilities

• Contribute to ASO strategy and app store testing.
• Help shape paywall and pricing strategies.
• Support user interviews and qualitative feedback loops.

Who You Are

• 2–5 years experience in product or growth roles on mobile apps.
• Comfortable with data, KPIs, and funnel metrics.
• Curious, entrepreneurial, and biased toward action.
• You like to figure things out, move fast, and test before overthinking.
• Strong communicator and team collaborator.
• Experience in early-stage or fast-paced environments.

Nice-to-Haves

• Knowledge of ASO and mobile subscriptions.
• Experience with no-code tools and rapid prototyping.
• Understanding of mobile dev workflows (sprints, backlog, QA).
• Full-time (CDI)
• Based in Paris (Boulogne-Billancourt office)
• Hybrid flexibility (office presence encouraged)
