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.

How We Work At Marble

  • We are a small, lean team of seasoned industry experts with the ambition to remake anti-fraud from the bottom up.
  • We plan for the long game but focus on fast value. We choose the simplest solution and iterate quickly. We compromise on feature breadth rather than security or usability.
  • We are opinionated, but set our ego aside. We discuss, commit, execute.
  • We are pragmatic and we execute fast on our decisions. We are perseverant when facing challenges but review plans if we hit a roadblock.
  • We excel at our job but work beyond our field of expertise. No task is below us.
  • We always take ownership - but also know when to share it.
  • We value output over input. We allow for flexibility and optimize for focus time.

The Details

  • Engagement: Part-time freelance contract, starting at 2 days/week.
  • Duration: 6+ months, with the potential to increase to 3+ days/week as we grow.
  • Location: Remote, within a UTC+0 to UTC+4 time zone (approx. +-2 hours from Paris).

  • Introductory Chat (30 min): A call with our CTO to discuss your experience, our mission, and the role.
  • Paid & Practical Work Assignment (~3 hours): A small, well-defined design task that reflects our daily challenges. We respect your time and expertise, so this assignment is compensated.
