• Design and implement stunning real-time animations and transitions for text, shapes, and media
• Integrate audio and video into the canvas with precise synchronization and playback control

• Comfort handling rich media video, audio, and image processing
• Strong focus on performance, optimization, and cross-browser compatibility
• Excellent collaboration and communication skills
• Prior experience building editors like Canva, Figma, or Adobe Express is a major plus
• Experience working on high-scale SaaS platforms is preferred
