Synthesia is the world's leading AI video platform for business, used by over 90% of the Fortune 100. The company is headquartered in London with offices across Europe and the US, and has raised over $530 million from premier investors including Accel, NVentures (Nvidia's VC arm), Kleiner Perkins, and GV, with a valuation of $4 billion.
You will lead design for Synthesia's AI Playground, a 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 is evolving from a single-format surface into a multi-format creation hub (video, images, motion graphics) with Templates & Apps ahead.
As a Staff (L6) Product Designer, you will operate as a senior individual contributor, setting design direction, influencing roadmap decisions with Product and Engineering leaders, and raising the craft bar on how generative tools feel. You will own Playground's evolution end-to-end, from single-format surface to scalable multi-format creation hub. You'll set design direction for discovery, experimentation, and iteration across all formats, and influence adjacent product areas (Studio, Media Library) to maintain coherence.
Key responsibilities include: designing prompt experiences and iteration workflows that make complex AI capabilities feel accessible and powerful; balancing discovery across multiple media formats 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; partnering with Product and Engineering to define quality standards and metrics; prototyping and testing interaction models quickly; and raising the bar on craft in prompt UX, format balance, iteration workflows, and the feel of creating with AI at speed.
You will work with users ranging from SMBs shipping quick marketing videos to Enterprise teams producing at scale, leveraging their feedback to ensure the product meets real needs.
Synthesia's culture emphasizes: Put the Customer First, Own it & Go Direct, Be Fast & Experimental, and Make the Journey Fun.
Benefits include 25 days annual leave plus public holidays, flexible work setup, generous referral scheme, and the ability to work from anywhere in the world for up to 60 days per year.
REQUIREMENTS:
- Significant experience designing creation tools or generative-media platforms where users explore, iterate, and refine outputs quickly
- Strong craft in interaction and visual design with a track record of shipping delightful experiences around complex workflows
- Deep comfort designing around AI model constraints; ability to design UX that works with constraints, not around them
- Systems thinking to hold the tension between Playground as a destination and as an on-ramp to Studio
- Experience designing multi-format products with ability to give equal weight to different experiences and scale beyond an initial focused surface
- Excellent communication in design reviews and cross-functional tradeoffs between user delight and business goals
- Track record of tackling novel problems in fast-moving generative-media spaces and turning early-stage bets into scalable platforms
