Product Designer, AI-Native Products (Staff-Level / L6)

Synthesia is the world’s leading AI video platform for business, used by over 90% of the Fortune 100. Founded in 2017, the company is headquartered in London, with offices and teams across Europe and the US. As AI continues to shape the way we live and work, Synthesia develops products to enhance visual communication and enterprise skill development, helping people work better and stay at the center of successful organizations. Following our recent Series E funding round, where we raised $200 million, our valuation stands at $4 billion. Our total funding exceeds $530 million from premier investors including Accel, NVentures (Nvidia's VC arm), Kleiner Perkins, GV, and Evantic Capital, alongside the founders and operators of Stripe, Datadog, Miro, and Webflow. The role: We're looking for a Staff (L6) Product Designer to lead design for some of Synthesia's AI-native, agentic Sessions product surfaces. Sessions are the experiences where employees learn through conversation, companies lrun a survey at scale, and AI becomes a direct participant in how work gets done - not just a tool behind the scenes. This area is central to redefining what a video platform can be: moving upstream from content creation into workforce development, and making complex AI capabilities feel natural, trustworthy, and effective for everyday users. You'll operate as a senior IC: setting direction, influencing roadmap decisions, shaping bets with Product and Engineering leaders, and raising the craft bar. In practice, this role is about solving AI-native design problems, for example: • Designing real-time, conversational avatar experiences that feel engaging and natural - not robotic or gimmicky - for employees learning and practising skills at work. • Creating interaction patterns for AI-driven workflows that give users the right amount of control, transparency, and trust without overwhelming them with complexity. • Improving output quality through better structure, guidance, and feedback loops - helping users understand what the AI is doing, catch issues early, and iterate with confidence. • Working at the frontier where AI changes what "interaction" means, and the best patterns are genuinely still being invented. In this role you will: • Own major AI-native bets end-to-end, from problem framing to shipped outcomes and iteration. • Set a design vision for our "Sessions" surface, and influence adjacent product areas to stay coherent. • Partner closely with Product and Engineering to define what "great" looks like (principles, quality bar, success metrics) and then drive toward it. • Prototype and test interaction models quickly - including novel agentic and conversational patterns - and know when high-fidelity matters. • Raise the bar on craft: interaction design, UI quality, systems thinking, and consistency across AI-native experiences. You should apply if you bring: • Significant experience designing complex, high-usage product surfaces - ideally including AI-native products, agentic features, conversational interfaces, or products where the system takes meaningful autonomous action. • Strong craft in interaction design and visual design, and a track record of shipping work that measurably improves the product experience. • Comfort operating in ambiguity: you can turn unclear and fast-moving problem spaces into crisp direction, and you do not wait for perfect clarity. • Systems thinking: you understand how AI capabilities, model constraints, and product architecture shape what's actually possible in the UX - not just what looks good on a screen. • Excellent communication in design reviews and cross-functional decision-making contexts. • Experience designing workflows where trust, transparency, and user control are central - helping users f
