Portfolio Jobs

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.

• Take design ownership of major product features from discovery through launch, shaping experiences that procurement teams will use daily
• Design the future of AI-powered procurement: create intuitive interfaces for agentic AI features that can negotiate contracts, analyze supplier data, and automate complex workflows while keeping humans in the loop
• Tackle uniquely complex design challenges: multi-stakeholder complexity, supplier collaboration, AI transparency and trust, and data-heavy interfaces that need to be powerful yet approachable

• Define and uphold quality standards and principles that make our product stand out in the crowded enterprise software landscape
• Build and evolve our design system, creating components and patterns that scale across an increasingly complex product
• Balance craft with velocity - know when to sweat the details and when to ship and iterate

• Conduct user research with buyers and suppliers to deeply understand their daily frustrations and needs
• Turn insights into actionable design opportunities, always connecting your work back to real user problems
• Collaborate tightly with product managers and engineers to ensure your designs are implemented with fidelity - and contribute to making them even better during development

• Establish lean, effective processes that support rapid iteration without sacrificing quality
• Mentor teammates on design thinking and elevate the overall craft across the company
• Be a vocal advocate for users and push back when technical or business constraints threaten the experience

• 5+ years of product design experience in B2B SaaS, enterprise software, or similar complex product environments
• Proven ability to simplify complex, multi-step workflows into intuitive experiences
• Strong proficiency with design systems - you've either built one or contributed significantly to one
• Exceptional visual design skills with high attention to interaction design, typography, and information hierarchy
• Experience collaborating closely with engineers and product managers in agile, fast-paced environments
• Fluency in both UX and UI - you're comfortable with user flows, wireframes, prototypes, and pixel-perfect mockups (we use Figma)
• Fluency in English, bonus points for German
• Valid work permit for Germany

• You're excited about designing for AI and understand the unique challenges of making autonomous agents feel trustworthy, transparent, and controllable
• You've designed for B2B or enterprise contexts where users have diverse needs and technical proficiency levels
• You're comfortable with ambiguity and can structure design problems that don't have obvious solutions
• You know that shipping good work beats perfecting work that never launches
• You validate your ideas with users and data, not just intuition or design trends
• You're opinionated about good design but humble enough to be wrong and change course
• You stay curious about emerging design patterns, tools, and the industries you're designing for

• You will have real ownership over one of Mercanis’ most strategic product areas, driving how our platform connects to enterprise systems.
• You will be part of a collaborative, knowledge-driven team that values innovation, learning, and impact.
• You will gain deep exposure to large-scale enterprise challenges, from system architecture to secure data interoperability.
• We offer a modern workspace in the heart of Berlin's vibrant startup scene, with the option to work remotely from time to time.
• You will be part of a culture built on transparency, curiosity, and continuous improvement, where great ideas win over hierarchy.
