Company mission
To disrupt how companies collaborate with their service providers, whilst increasing transparency in the selection process.
Role
Who you are
- 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
- Please confirm that you have understood that this role is based in Berlin and Office-first
Desirable
- 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
What the job involves
- 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
Our take
Mercanis sets out to overturn procurement, supplying digital solutions that enables users to streamline sourcing, supplier management, contract management and spend analysis. In an industry where digitisation has been slow, this helps businesses to avoid missing out on cost-saving procedures and optimised productivity.
The company's offering lets procurement specialists work on strategic tasks through smart automation, leveraging data to help them make better decisions. In doing so, Mercanis is disrupting how companies collaborate with their service providers, whilst increasing transparency in the selection process.
This approach makes buying services smarter and more efficient, while also ensuring compliance. Its an attractive idea that has earned Mercanis a good amount of backing which it can use to expand its footprint and continue further development efforts.
