Android Runtime Engineer - DevRel Team

Rive is where designers, animators, and developers build interactive experiences. Design, animate, and code in one place. What you build in the editor is what ships in your app, game, or website. No mockups, no prototypes, no handoff. The real thing. Companies like Spotify, Duolingo, LinkedIn, Google, and Fortune 500 automakers use our open‑source runtimes to build once and ship everywhere — websites, apps, games, and vehicles. With Rive, designers and developers work with the same tools. No silos. What you see in the editor is what ships in production.
