About us

Marble is a fintech infrastructure startup, backed by VCs and Hexa .

We build a groundbreaking open-source decision engine for banks, payment service providers and marketplaces.

The Opportunity: Your Mission

As our first dedicated Product Designer, you will have a unique opportunity to shape the user experience of a powerful, data-rich platform from the ground up. Your mission is to translate the complexity of fraud detection and investigation into a simple, intuitive, and powerful interface for our users. You'll work directly with the founders to set the design vision and create a product that not only looks good but empowers financial institutions to make critical decisions with confidence.

What You'll Do

• Own the end-to-end design process, from wireframes and user flows to high-fidelity mockups and interactive prototypes.

• Design intuitive dashboards, complex data visualizations, and streamlined workflows for new and existing features (approx. 2/3 of your time).

• Elevate and unify our existing product experience, focusing on improving navigation, usability, and overall UX.

• Build, maintain, and extend our Design System in Figma to ensure consistency and accelerate development.

• Collaborate closely with the CEO, CTO, and two front-end developers in a tight feedback loop, balancing user needs, technical constraints, and business goals.

Who We're Looking For: Skills & Experience

• A Proven B2B/SaaS Designer: You have a strong portfolio with a proven track record of designing complex, user-facing web applications. Experience with enterprise software, analytics dashboards, or the fintech/banking sector is a significant plus.

• A UX Strategist: You excel at making the complex simple. You design interfaces that don't just look good but feel intuitive, and you obsess over edge cases to create a robust user experience.

• A Figma Pro: You are highly proficient with modern Figma practices, including auto-layout, variants, and creating scalable Design Systems.

• A Pragmatic Collaborator: You thrive working hand-in-hand with developers. You know how to communicate design decisions clearly, give and receive constructive feedback, and find pragmatic solutions.

• Detail-Oriented: You can design for a range of screen sizes (desktop-focused) and are mindful of challenges like internationalization.

• Team Player: You're willing to occasionally assist with visual assets for our website or blog to ensure brand consistency across all touchpoints.
