Monstro•New York, NY

About The Position

As a Senior Mobile Product Designer, you will play a key role in designing and building out our Android application from the ground up. This role will be heavily focused on creating intuitive, high-quality native mobile experiences across onboarding, financial workflows, AI-powered interactions, and core user journeys as we expand the Monstro platform onto Android. You’ll own the end-to-end mobile design process—from early concepts and user flows through high-fidelity production designs—working closely with product and engineering to bring scalable, production-ready experiences to life. While the immediate focus will be Android, you’ll also contribute to broader mobile and product initiatives across the platform as the company grows. You’ll help establish mobile UX standards, interaction patterns, and scalable design systems that drive usability, trust, engagement, and long-term product quality across Monstro’s mobile ecosystem.
