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
