Senior Frontend Software Engineer, Rodeo

WHO WE ARE At Twelve Labs, we are pioneering the development of cutting-edge multimodal foundation models that have the ability to comprehend videos just like humans do. Our models have redefined the standards in video-language modeling, empowering us with more intuitive and far-reaching capabilities, and fundamentally transforming the way we interact with and analyze various forms of media. With a remarkable $107 million in Seed and Series A funding, our company is backed by top-tier venture capital firms such as NVIDIA’s NVentures, NEA, Radical Ventures, and Index Ventures, and prominent AI visionaries and founders such as Fei-Fei Li, Silvio Savarese, Alexandr Wang and more. Headquartered in San Francisco, with an influential APAC presence in Seoul, our global footprint underscores our commitment to driving worldwide innovation. We are a global company that values the uniqueness of each person’s journey. It is the differences in our cultural, educational, and life experiences that allow us to constantly challenge the status quo. We are looking for individuals who are motivated by our mission and eager to make an impact as we push the bounds of technology to transform the world. Join us as we revolutionize video understanding and multimodal AI. ABOUT THE ROLE We’re hiring a Frontend Engineer to craft the interaction layer of Rodeo — a video-centric creative tool where microinteractions, animation, and polish define the product experience. This is a design-forward frontend role where you’ll own the feel of the product: transitions, motion, responsiveness, and the small details that make professional tools feel intuitive. You’ve built interfaces where craft matters — creative tools, editors, or media-rich products where users notice the difference between good and great. You have strong opinions about easing curves, frame budgets, and interaction patterns, and you’re energized by collaborating closely with design to push what’s possible in the browser. This role requires travel to our San Francisco headquarters on a quarterly basis for team offsites and company events, as well as approximately one week per month of in-person collaboration with the Rodeo team in the Los Angeles area.
