Senior Product Manager (New Product Line & Portfolio Growth)

Senior Product Manager at Appstero. Full-time, hybrid in Warsaw (2 days office, 3 remote). Own strategy for subscription portfolio and launch new privacy & security consumer product (iOS/Android). Competitive salary, discussed individually.

We are looking for a product manager who will both add durability to our current subscription business and launch a new consumer product in privacy & security (iOS + Android). The role is hands-on IC-to-lead: you decide what to build and why, based on cohorts and real user behavior, and drive it to launch. If you are equally confident about unit economics and UX, love taking a product from hypothesis to soft launch, and do not wait for someone to write a brief — this post is for you. Responsibilities: – Own end-to-end product strategy across two directions: the existing portfolio and the new privacy & security product – In the first 6 weeks — validate willingness-to-pay and pricing on current products, assemble UX for the new product MVP, take it to soft launch in CA/AU, then US/UK – Prioritize the roadmap based on funnels, cohorts, churn curves, LTV/CAC — by data, not intuition – Design and interpret experiments around onboarding, pricing, paywalls, retention – Work closely with engineers on scope decisions and with the growth team on acquisition and monetization mechanics – Connect product decisions with conversion, retention, ARPU, LTV across different horizons – Ensure engineers, design, growth, marketing, and support move in one direction

5+ years in product management with evidence of independently owning a consumer product from strategy to launch and measurable results – Experience with a consumer mobile subscription product, where you personally influenced activation, conversion, retention, churn or LTV – Strong quantitative fluency: funnels, cohorts, churn curves, LTV/CAC models — ability to make a prioritization call independently – Hands-on experimentation mindset — A/B tests around onboarding, pricing, paywalls, retention – Strong consumer UX instincts and comfort in scope discussions with engineers – Experience building or evolving an MVP under real time/resource constraints – Commercial mindset — product decisions in the language of conversion, retention, ARPU, LTV – Ownership, low-ego, high-accountability, strong cross-functional communication – English B2 or higher Nice to have: – Experience in consumer privacy, cybersecurity, VPN, password management, or adjacent subscription categories – Experience with App Store / Google Play launches and subscription pricing mechanics (plans, trials, paywalls, packaging) – Experience partnering with performance marketing / growth teams transitioning to product-led / owned growth – Experience with AI-powered consumer products — ability to distinguish genuinely useful AI capabilities from positioning features
