Product Designer, Generative Media (Staff-Level / L6)

Skills this job asks for

About the role

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. Location: Europe remote or London hybrid THE ROLE: We're looking for a Staff (L6) Product Designer to lead design for Synthesia's AI Playground: our dedicated generative-media workspace where users experiment with leading AI models to create video clips, images, and motion graphics, then feed those assets into Synthesia Studio videos. Playground sits at an intentional crossroad: it's both a creation destination in its own right and a strategic on-ramp that converts experiments into polished videos. The product is evolving rapidly - from a single-format surface into a multi-format creation hub (video, images, motion graphics) with Templates & Apps ahead. You'll operate as a senior IC: setting direction, influencing roadmap decisions (not just contributing), shaping bets with Product and Engineering leaders and raising the craft bar on how generative tools actually feel. In practice, this role is about solving generative-media design problems, for example: - Designing prompt experiences and iteration workflows that make complex AI capabilities feel accessible and powerful - giving users meaningful agency without overwhelming them. - Balancing discovery across multiple media formats so none feels buried, while scaling for Templates, Apps, and future workflows. - Designing the invisible handoff between Playground creation and Studio editing - so experiments flow naturally into polished videos. - Working at the frontier of how generative media changes what "creation" means, where the best patterns are genuinely still being invented. IN THIS ROLE YOU WILL: - Own Playground's evolution end-to-end: from single-format surface to scalable multi-format creation hub. - Set design direction for discovery, experimentation, and iteration across all formats. Influence adjacent product areas (Studio, Media Library) to stay coherent. - Partner with Product and Engineering to define what "great" looks like (principles, quality bar, metrics) and drive toward it. - Prototype and test interaction models quickly. Know when high-fidelity matters versus learning through Lo-Fi. - Raise the bar on craft: prompt UX, format balance, iteration workflows, and the feel of creating with AI at speed.
