Senior Mobile Developer

We are on a mission to empower designers and developers worldwide and are trying to fundamentally change the nature of creation and motion. LottieFiles has proven that relevant design assets and motion graphics evoke emotion and humanizes apps and platforms.

We have assembled one of the largest communities in our industry with over a million raving fans from over 70,000+ companies (Google, TikTok, Disney, Uber, Airbnb, and Netflix etc) who use our platform and tools every day to enhance their workflow and ship incredibly engaging content.

On average, a new lottie file is uploaded to the platform every 15 seconds. These assets range from simple animated icons to animated product onboarding and walkthroughs, system animations on smartwatches, interactive infographics for online publications, and countless other use cases across devices.

Lottie, a revolutionary format, can be best described as a movement, and LottieFiles is a company wrapped around it. By listening to the Lottie community, we’ve created a unique set of editing, workflow, and collaboration tools that seamlessly integrate with popular design software and developer environments such as Adobe After Effects, Figma, VS Code, and others. To make things easier for non-motion designers, users can take advantage of tons of free content available on our platform to get started too.
