Senior Full Stack Engineer

Motion is creating the command center for creative strategists: an AI-driven analytics and intelligence platform that bridges the gap between performance marketers and creative teams, helping them uncover what's working, what's not, and ultimately ship more winning ads across platforms like YouTube, LinkedIn, Meta, and TikTok.
Today, Motion is trusted by some of the world's top e-commerce and direct-to-consumer brands and agencies (including Vuori, True Classic, The Farmer's Dog, and HexClad) and has analyzed over $12 billion in media spend. When leading brands want to understand their creative performance, they turn to us.
We're growing fast (3x year-over-year), our product is sticky, and with a recent $30M Series B raise, we're just getting started. We're building the future of creative intelligence and are looking for talented people to help us get there
