Senior Product Designer

Senior Product DesignerMadrid OfficeEngineering – 13001 - Engineering /Permanent Full Time Employee /Hybridapply for this job Aircall is a unicorn, AI-powered customer communications platform used by 22,000+ companies worldwide to drive revenue, resolve issues faster, and scale customer-facing teams. We’re redefining customer communications by bringing voice, SMS, WhatsApp, and AI together into one seamless workspace.   Our momentum comes from a simple idea: help teams work smarter, not harder. Aircall’s AI Voice Agent automates routine calls, AI Assist streamlines post-call work, and AI Assist Pro delivers real-time guidance so people can do their best work. The result is higher revenue, faster resolutions, and teams that scale with confidence.   Aircall is headquartered in Paris, our European HQ, with a strong North American presence anchored in Seattle, our North American HQ, and teams across Madrid, London, Berlin, San Francisco, New York City, Sydney, and Mexico City. We’ve built a product customers love and a business that’s scaling quickly, backed by world-class investors and driven by rapid AI innovation across multiple product lines. At Aircall, you’ll join a company in motion. We’re ambitious, product-driven, and execution-focused, with visible impact, fast decisions, and real growth.   How we work at Aircall: We’re customer-obsessed, data-driven, and focused on delivering meaningful outcomes. We value ownership, continuous learning, and thoughtful speed. If you thrive in a collaborative, fast-moving environment where trust and impact matter, you’ll feel at home here.   Within Aircall, we are launching a specialized New Product Unit to build the future of autonomous sales. We are improving the AI Orchestration Layer—a system that records and understands every customer interaction (calls, video, email, WhatsApp) to autonomously execute sales workflows: CRM updates, follow-ups, task creation, and coaching insights.  Our long-term vision is to evolve this into a self-improving, agentic Sales OS—where specialized AI agents collaborate, coordinate, and continuously optimize the revenue process. The RoleWe are looking for a Senior Product Designer to join Aircall. This is a unique role where you will act as our founding designer. It is a fast, lean, and obsessively accountable. You will be the design voice of the product: the person who owns the experience end-to-end, sets the quality bar, and makes the calls that shape how thousands of sales people interact with AI every day. This is not a role where you wait for tickets. You will improve what exists, fix the legacy we've accumulated while moving fast, and design what's coming next — the future of AI in voice and communication. You'll do all three at once, and you'll decide which trade-offs are worth making to ship. This role is for someone senior and self-directed — someone who already knows what good UI and good UX look like, and doesn't need a playbook to get there. You understand design systems, interaction patterns, and the difference between polish that matters and polish that doesn't. You move fast without losing craft, and you know perfection is the enemy of progress in a startup. You'll partner extremely closely with our Leadership team — but you're expected to challenge, not just execute. You'll bring opinions, defend them, and change your mind when the user proves you wrong. And you'll stay close to the client: discovering problems on calls, in data, and in the product itself, sometimes together and sometimes entirely on your own. What You’ll Do In this role you will own product design end-to-end — from discovery and interaction design to high-fidelity execution and the design system that holds it all together. Design & Craft Own the experience: Drive the end-to-end product experience — flows, interaction design, and high-fidelity UI — for a complex AI product used daily by sales teams. Fix the legacy: Audit and systematically improve the experience and...
