Cello is hiring a Senior Product Designer to help define the next generation of its product as the company moves toward a more self-serve, product-led model. You will partner with our founding designer and cross-functional teams (product and engineering) to own the end-to-end design of the core experience, from problem framing to shipped solution. You will identify opportunities to improve existing product areas, refine and scale the evolving design system, and design thoughtful mockups and interactive prototypes across product, marketing, and brand surfaces. You will also help ensure embedded UI feels native, trustworthy, and coherent across diverse use cases. Requirements: at least 5 years of software design experience with SaaS products; strong breadth across visual design, product thinking, brand, and interaction design; systems thinking; proficiency in Figma and prototyping tools; excellent collaboration and communication in async environments; comfort in a fast-paced startup. Nice-to-have: in-house and/or agency experience, experience with embedded platforms or developer-facing tools, and exposure to data-heavy or AI-assisted product experiences. This is a remote-first role based in Europe (must be within CET +/-3 hours).
