What you'll do
We're looking for a UX/UI Designer who brings equal strength in user experience thinking and interface craft. This role sits at the intersection of both disciplines: you'll define how users move through the product and how it looks and feels when they get there.
In practice, roughly half your time will be on UX - wireframes, flows, and usability - and half on UI execution: working directly in our Figma design system to produce polished, production-ready interface designs. The UI half is where we need the highest bar. We have been establishing a design system, named Gladus, that needs a designer who can work within it rigorously, extend it thoughtfully, and raise the visual and interaction quality of everything it touches.
This is a craft-forward, hands-on role. You'll collaborate closely with technical product managers and owners, web application team leads and engineers, and, when relevant, within research initiatives - but you'll spend most of your time doing, not coordinating.
Key responsibilities:
UI design & design system
-
Design high-fidelity screens and components directly in Figma, working within and extending our existing design system, Maintaining component consistency across our portals and products
-
Apply strong visual judgment to typography, spacing, color, iconography, and layout - not just functional correctness but visual quality
-
Collaborate with engineers and technical product owners during handoff and QA to ensure pixel-level implementation fidelity
UX design & flows
-
Create wireframes and interaction flows that define user journeys before moving to high-fidelity
-
Apply information architecture principles to ensure navigation and structure are intuitive
-
Use product analytics to identify where users struggle and translate that into concrete design changes
Collaboration
-
Partner with technical product managers to understand requirements and push back when the scope would compromise the user experience
-
Work with user and customer experience research conclusions to consume and apply user insights - you won't lead research, but you'll act on it.
-
Participate in design critiques with evidence-based rationale for your decisions
-
Contribute to design system documentation so your work is usable by the rest of the team
What you'll need
-
2–5 years of experience in UX/UI or Product Design, ideally in an in-house environment, with a portfolio demonstrating both UX thinking (e.g., user flows, wireframes) and high-fidelity UI execution, including the rationale behind design decisions
-
Strong proficiency in Figma, including components, variants, auto-layout, design tokens, prototyping, developer handoff, and working within established design systems
-
Solid understanding of UX and interaction design principles, including information architecture, user flows, visual hierarchy, typography, spacing, color, micro-interactions, loading states, and accessibility standards (WCAG 2.1 AA)
-
Experience collaborating closely with developers and cross-functional teams, with the ability to translate design concepts into implementation-ready specifications
-
Ability to leverage user research insights and industry best practices to create intuitive and user-centered experiences
-
Strong analytical, problem-solving, and communication skills, combined with a high level of empathy, attention to detail, and a collaborative, solution-oriented mindset
-
Fluent German and English language skills
