Your Mission

We are currently looking for a Founding Product Designer.

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

Used by over 10 million end users each month, Cello is embedded directly into customers’ products. This role owns the end-to-end product experience - across end users, operators, and AI‑assisted workflows - designing scalable, interaction‑first systems that unlock new growth use cases in an increasingly automated, AI‑driven world.

⭐ TL;DR

• Seed, GrowthTech
• Remote‑first (+/-3 CET)
• Competitive base salary + significant equity

⭐ Why join

• Unique growth opportunity: early‑stage GrowthTech start‑up backed by top‑tier investors like HV Capital, ByFounders, TinyVC, and operator angels from YouTube, Personio, and Workday
• Complex and interesting product: APIs, attribution models, recommendation engines, and more.
• Strong momentum: Software companies need cost‑effective customer acquisition channels → we’re the solution.
• We have >>10M users on the Cello platform and work with iconic customers like Miro, Typeform and Veed.
• Become a central part of an experienced and passionate co‑founding team on our journey to a truly great company (ex‑Twilio, ex‑Wise, ex‑Skype, etc.), +40% of the team consists of former founders

⭐ Your responsibilities

• You will define and own Cello’s design foundations, including principles, patterns, and a scalable design system
• You will lead end‑to‑end product design across core experiences, from early concepts to shipped product
• You will partner closely with product, engineering, and leadership to shape solutions early and holistically
• You will design clear, user‑centred experiences for end users, growth teams, partners, and developers
• You will shape how the Cello SDK integrates into customer products and how developers build on top of it
• You will use user research and product data to inform decisions, validate assumptions, and iterate quickly
• You will raise the design bar through hands‑on work, strong critique, and continuous improvement of how design is done
• You will ensure a coherent product and brand experience across key customer touchpoints, including the website

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

• Senior experience in product / UX / interaction design (+7 years of experience)
• Proven track record on products that scaled in users, complexity, or scope (ideally B2B SaaS or platforms)
• Strong interaction and visual design skills across complex, end‑to‑end flows
• Experience designing under real constraints and making tradeoffs with product and engineering
• Comfortable owning ambiguous problems end‑to‑end in a fast‑moving, high‑ownership environment
• Experience working alongside product and engineering to make difficult tradeoffs.

Nice‑to‑have

• Experience with embedded products, platforms, or developer‑facing tools
• Exposure to AI‑assisted or data‑heavy products
• Experience defining design systems or standards, ideally in early‑stage teams

Not a fit if

• Your background is primarily marketing or brand design
• You rely on fully specified requirements or handoff‑based workflows
• You prefer people management over hands‑on product design
• You’re not comfortable with embedded, constraint‑heavy products

Benefits

❤️ In the end, it’s all about the team and our culture. Understand why we love our job and see what it’s like to work at Cello in our People Playbook (bit.ly/cello-people-playbook). We have some compelling perks and benefits.
