Product Case Studies & Systems Thinking

During the process, you may face a case study or a product-oriented discussion. This evaluates your ability to think like a product owner, analyze user flows, and design systems rather than isolated screens.

Be ready to go over:

• User Journey Mapping – Structuring complex B2B workflows with multiple user personas.
• Data-Driven Design – How you use metrics, usability testing, and analytics to inform your design decisions.
• Marketplace Mechanics – Understanding the relationship between operators, sellers, and buyers in a platform ecosystem.

Example questions or scenarios:

• "If you were tasked with redesigning the seller catalog upload process, what metrics would you track to measure the success of your design?"
• "How do you design a dashboard that serves both a high-level business operator and a day-to-day logistics manager?"

As a UX/UI Designer at Mirakl, your day-to-day work will be fast-paced, collaborative, and highly focused on product delivery. You will own product features from concept to launch, working closely with dynamic, agile teams.

• Upholding and Scaling the Design System: You will contribute to Mirakl's global design system, ensuring that your components are reusable, accessible, and aligned with the company's design standards.
• Conducting Focused User Research: While UI execution is highly prioritized, you will conduct targeted usability testing, user interviews, and research to validate your design solutions and advocate for the end-user.
• Iterating Based on Feedback: You will continuously gather feedback from internal stakeholders, clients, and user data to iterate on shipped features and drive continuous product improvement.

To be competitive for the UX/UI Designer position at Mirakl, you need to demonstrate a strong track record of designing complex digital products. The hiring team looks for a specific blend of visual talent and technical execution.
