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.

Your Responsibilities on this role

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

Build a Design System that scales

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

Drive Design Decisions with Research

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

Shape how we work

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

Role requirements

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 Berlin and Office-first

What Sets You Apart

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

Why to join us here at Mercanis?

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
