Mirage is redefining short-form video with frontier AI research.
We’re building full-stack foundation models and products that are changing the future of this format and video creation, production and editing more broadly. Over 20 million creators and businesses use Mirage’s products to reach their full creative and commercial potential.
We are a rapidly growing team of ambitious, experienced, and devoted engineers, researchers, designers, marketers, and operators based in NYC. As an early member of our team, you’ll have an opportunity to have an outsized impact on our products and our company’s culture.

DOMAIN EXPERIENCE

• Exposure to diffusion models, multimodal video generation, or large-scale generative architectures.
• Experience with distributed training frameworks (FSDP, DeepSpeed, Megatron-LM) or HPC environments.

ABOUT THE ROLE:

Captions is seeking a Machine Learning Engineer to partner closely with our Researchers and bring large-scale multimodal video diffusion models into production. You’ll be responsible for optimizing and deploying state-of-the-art generative models (tens to hundreds of billions of parameters) to deliver low-latency, high-throughput inference at scale. This is a unique opportunity to work on cutting-edge AI—spanning audio-video generation, diffusion architectures, and temporal modeling—and ensure these innovations reach millions of creators worldwide.
