At Fonoa, we are transforming how digital-first companies stay tax compliant. We provide simple and modular API solutions that easily integrate into any existing workflow. Through our technology-first approach, we reduce manual processes, increase compliance and reduce the cost of operations when transacting and scaling internationally.

Role Description

We're looking for a Staff Product Designer to help shape the future of Fonoa's AI-native Tax Operating System. You'll design new AI-powered products and experiences, simplify complex tax workflows, and help define the future of our platform.

You'll join an independent Design organization, working alongside a high-caliber team of designers, product managers, engineers, and tax managers. As one of our senior individual contributors, you'll have the opportunity to shape our products, influence a brand new design system from the ground up, and raise the quality bar across everything we build.

This is a hands-on Staff IC role reporting to the Head of Design, with a strong focus on systems thinking, craft, and execution.

What you'll do

• Shape the next generation of Fonoa. Design new AI-powered products and experiences that become core parts of our Tax Operating System.




• Own products end to end. Lead the design process from problem framing and research through interaction design, visual craft, prototyping, and launch.




• Simplify complexity. Turn sophisticated tax, regulatory, and AI workflows into intuitive experiences that customers trust.




• Think in systems. Design scalable foundations, contribute to our new design system, and create patterns that enable future products.




• Partner across disciplines. Work closely with Product, Engineering, AI, Tax, and User Research to shape product direction, not just execute requirements.




• Raise the quality bar. Champion exceptional craft, attention to detail, and thoughtful execution across everything we build.

What we're looking for

• Exceptional product craft. You care deeply about interaction design, visual quality, motion, and the details that make products feel effortless.




• Strong systems thinking. You can design both individual experiences and the larger product architecture behind them.




• Experience building design systems. You've created or significantly evolved systems that scale across products and teams.




• Complex product experience. You've designed sophisticated B2B, enterprise, fintech, developer, or infrastructure products where simplifying complexity was central to your work.




• AI curiosity. You're excited about designing AI-native experiences that solve real customer problems, not just adding AI for its own sake.




• A strong portfolio. Your work demonstrates end-to-end ownership, clear thinking, and measurable impact, not just polished visuals.




• Collaborative mindset. You communicate clearly, challenge ideas thoughtfully, and enjoy working closely with cross-functional teams.
