🚀 Role Summary

• Drive the design strategy and execution for Monument's established Savings product, focusing on scaling and enhancing user experience for the mass affluent demographic.

• Lead design initiatives from initial research and concept development through to successful implementation and market launch of scaled features.

• Champion a hypothesis-led, data-validated experimentation cadence to optimize key user journey metrics such as activation, retention, and lifetime value.

• Translate complex financial concepts and regulatory requirements into clear, intuitive, and trustworthy digital experiences.
