What We’re Building

Cello helps businesses turn their users into their best acquisition channel. Our product is the easiest way to embed user and partner referrals directly into the products you love to use. With just a few lines of code, a company is set up for hyper growth that runs on autopilot instead of spending money on ads.

Teams at Bolt, Miro, Typeform, VEED, and Descript already run their referral programs on Cello. which is proof that word-of-mouth can be engineered as a real growth channel, not being a nice to have.

We're a small, remote-first team that builds infrastructure that lives in other people's products. That means our bar for craft and attention to detail is exceptionally high. Our UI has to feel native inside other people's products that we don't control, our components have to hold up wildly across different use cases, and our decisions get scrutinized by the world's best growth, design and engineering teams. So in addition to caring deeply about how things look and feel, we need people who can think in systems, tracing how a decision plays out across different user segments and across levels of the product.

Your Mission

⭐ Cello is looking for a Senior Product Designer to help define the next generation of its product as the company moves toward a more self-serve, product-led future.

We're looking for a senior product designer to work closely with our founding designer, product and engineering teams on the core Cello experience. You'll be involved in every aspect of the product design cycle and expected to take ownership of the work end-to-end.

• You partner directly with our founding designer, product and engineering teams to take projects on our roadmap from rough problem to shipped solution.

• You look for opportunities to improve our existing product areas. Sometimes that's a full rethink of how something works, others it’s fixing smaller quality issues you pick up in the product.

• You use and improve our evolving design system (product design, marketing and brand design).

• You design mockups and prototypes in low- and high-fidelity to communicate ideas and show how things might work.

• You are part of and contribute to a growing design culture that's still taking shape.

• You sweat the details that make embedded UI feel trustworthy.

About You

🛠️ We care less about your exact background and more about how you think and build. You’re curious, hands-on, and motivated by shaping meaningful products - comfortable operating with ownership, ambiguity, and scale as Cello grows.

Required

• 5+ years of software design experience

• Designed software for SaaS businesses, but we also love to see a range in the type of products you’ve worked on.

• Breadth of craft: You’re able to comfortably flex across visual design, product thinking, brand, and interaction design.

• Systems thinking: you can design components and patterns while thinking about how they fit into the broader system, but you also know when to push past convention and innovate.

• Courage to challenge ideas, try new things and push a product direction forward.

• Fluency in designing Figma and other prototyping tools. You also experiment regularly with new tooling.

• Strong collaboration and communication skills. We have an async work culture.

• Comfort working in a fast-paced startup environment, where the stakes are high and priorities can shift quickly.

Nice-to-have

• Bonus points if you have both in-house (especially at a startup) and agency experience.

• Experience with embedded products, platforms, or developer-facing tools

• Exposure to data-heavy or AI-assisted product experiences
