About The Position

We are seeking a Senior Product Designer to take full ownership of the end-to-end product design process. You will work on clearly defined problems in close collaboration with the Product Team, from ideation and prototype testing to ready-to-ship visual designs. You will collaborate with our existing Product Designer to evolve our design language and ensure a cohesive experience across both sides of the platform. You will 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. Your responsibilities will include translating concepts into high-fidelity designs, adhering to and maintaining our scalable design system in Figma, and crafting clear, engaging UI copy to guide users through the product.

Requirements

• 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 Haves

• 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.
