Senior Product Designer; m​/f​/d

Your mission at Mercanis

Join us in changing an entire industry.

To disrupt the status quo, we are seeking motivated hustlers, optimistic go-getters, and versatile thinkers with the passion and determination to reach for the stars together. The procurement industry is undergoing the "iPhone Moment" led by Mercanis. After securing our 30 million USD total in funding, you have the opportunity to be a disruptor early on in this exciting journey. We're seeking a designer who obsesses over how things work, not just how they look.

Elevate UX across the Product

• Take design ownership of major product features from discovery through launch, shaping experiences that procurement teams will use daily
• Audit and improve user flows across all modules: identify friction, inconsistency, and complexity that doesn't need to exist
• Own interaction design for our most challenging workflows: multi-step approvals, supplier collaboration, bulk operations, agentic AI-interactions

• Structure the system for AI-assisted prototyping (Figma Make and similar tools), so we can generate design-aligned screens quickly and reserve your craft for complex interactions
• Establish quality gates: what can be AI-generated vs. what requires hands-on design craft
• Document usage guidelines clearly enough that humans and machines can produce consistent and high-quality design work

• Conduct user research with buyers and suppliers to deeply understand their workflows and needs
• Validate interaction patterns through prototyping and testing before committing to production
• Turn insights into actionable design opportunities, always connecting your work back to real user problems

• Define where design effort should focus vs. where systemized patterns and tooling can handle it
• Mentor teammates on design thinking and elevate the overall craft across the company
• Collaborate closely with PMs and engineers to ensure flows survive implementation

Required

• 5+ years of product design experience in B2B SaaS, enterprise software, or similar complex product environments
• Demonstrated ability to simplify complex, multi-step workflows into intuitive experiences
• Strong experience building or contributing to design systems
• Hands-on experience with AI design tools and structuring design systems for machine-readability
• You think in flows and states, not just screens, interaction design is your craft
• Comfortable with ambiguity and unstructured problems in an agile, fast-paced environment
• Deep Figma proficiency
• Fluency in English, bonus points for German
• Valid work permit for Germany
• Please confirm that you have understood that this role is based in B
  erlin and Office-first

• You've designed for B2B or enterprise complexity: long workflows, diverse user expertise, data-dense interfaces
• You're excited about designing for AI and understand the unique challenges of making autonomous agents feel trustworthy, transparent, and controllable
• You're interested in how AI tooling can change the design process - not threatened by it
• You validate your ideas with users and data, not just intuition or design trends
• You're opinionated about good UX but humble enough to be wrong and change course

• Shape the UX of an entire product suite, not just isolated features
• Work on genuinely hard problems: procurement software is underserved and ready for thoughtful design
• Collaborative, low-ego team that values impact over hierarchy
• Modern office in central Berlin
• Work with the system of your choice - whether it's Apple, Windows, or Linux, you decide
• Competitive compensation and early-stage equity
