Sr. Product Designer

Your mission

• Take full ownership of the end-to-end product design process, working on clearly defined problems in close collaboration with the Product Team — from ideation and prototype testing to ready-to-ship visual designs.

• Collaborate with our existing Product Designer to evolve our design language and ensure a cohesive experience across both sides of the platform.

• Work hand-in-hand with our product and engineering teams, identifying high-impact UX opportunities and delivering solutions that are technically feasible and ship fast.

• Translate concepts into high-fidelity designs, adhering to and maintaining our scalable design system in Figma.

• Craft clear, engaging UI copy to guide users through the product.

Your profile

Must-have:

• 3–5 years of experience as a Product Designer in a well-known B2B SaaS company or high-growth SaaS startup.

• Proven ability to design complex, desktop-first B2B web applications end-to-end — from problem framing to interaction design and handoff, ideally demonstrated in your portfolio.

• Strong product thinking: Ability to find pragmatic “80/20” solutions that balance user value, technical constraints, and business goals.

• Expert-level Figma skills and experience collaborating with other designers in shared workspaces, including component libraries and design systems.

• Self-driven, outcome-oriented, able to work independently while communicating trade-offs and constraints clearly.

• Native German speaker with fluent English.

Nice-to-have:

• Experience using AI-assisted coding tools (like Claude code, cursor etc) to build realistic, functional prototypes.

• Foundational understanding of HTML/CSS to ship smaller improvements to the product or website yourself.

• UX copywriting experience.
