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 value diverse backgrounds and encourage you to apply even if you didn’t follow the traditional career path. We’re always looking for individuals who can bring a new perspective.
Required
Senior experience in product / UX / interaction design (+7 years)
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 trade‑offs 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 trade‑offs
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.
