As Senior Product Manager – Identity & Growth , you will lead the end-to-end vision, strategy, and execution for our registration and authorization funnels—balancing seamless conversion against fraud prevention, security, and strict global compliance (GDPR, data privacy, and localization). Partnering cross-functionally with Design, Engineering, Security, and executive stakeholders, you will align complex product roadmaps and own the domain’s unit economics, optimizing critical operational costs like SMS/OTP without compromising verification rates. Combining deep analytical expertise in session stitching and high-frequency A/B testing with a risk-based onboarding approach, you will champion high-converting, compliant, and cost-effective identity experiences that fuel sustainable growth. Key Responsibilities Boost sign-up and login conversion rates by designing smart onboarding flows that keep user friction low while keeping fraud and security risks under control. Partner with design and research teams to create simple, accessible, and intuitive user experiences that prevent drop-offs. Bring business, engineering, and security teams together to build, align, and execute complex product roadmaps. Take ownership of domain costs—building financial models and finding ways to cut expensive communication costs (like SMS/OTP) while keeping completion rates high. Stay ahead of technical debt, project risks, and data privacy laws (like GDPR and local localization rules) by designing compliant flows that don't hurt conversion. Use advanced analytics including session stitching and high-frequency A/B testing—to deeply understand user behavior across platforms and continually optimize performance.
