Research Scientist - LTX Video

Lightricks, an AI-first company, is revolutionizing how visual content is created. With a mission to bridge the gap between imagination and creation, through AI technology, we bring cutting‑edge products to the creative and business spaces. Our advanced AI photo and video generation models, including our open‑source LTX‑2 model, power our apps and platforms:
Facetune, LTX, LTX Scaler, Photoleap, and Videoleap, enabling creators and brands to leverage the latest research breakthroughs, offering endless control over their creative potential. Our influencer marketing platforms, Popular Pays, provide influencers with the ability to scale their content and monetize their work, while offering brands opportunities to expand their reach through tailored creator partnerships.

Following the success of LTX‑2, our widely adopted open‑source text‑to‑video model, we are expanding our efforts to develop cutting‑edge video generation models and are hiring Research Scientists to join our LTX‑2 Core team.

At Lightricks, we’ve been at the forefront of innovation in text‑to‑image and text‑to‑video generation, with LTX‑2 driving our flagship product, LTX, and gaining significant traction in the research and open‑source communities, including integrations with platforms like Comfy

UI and Diffusers.
