Research Scientist

Mirage is an AI-native video platform that intelligently orchestrates production and editing through natural language. Our models leverage contextual awareness to execute the same creative decisions a professional editor would dramatically improving productivity for experienced teams, while making video creation accessible to anyone. We're an interdisciplinary team addressing some of the most difficult technical and creative challenges in generative media. As an early member of our team, you'll tackle foundational problems that remain largely unsolved across the industry, driving an outsized impact on the future of creative expression.

Mirage is seeking a Research Scientist to advance the frontier of multimodal video generation. You'll work on novel modeling approaches, training objectives, and scaling strategies for large-scale video models, contributing directly to systems used by millions of creators.

You'll focus on pushing generation quality, controllability, and realismespecially in facial expression, audio-to-video synchronization, human motion, expression, and storytellingwhile validating ideas through real-world product impact.

Responsibilities

• Develop novel approaches to video and multimodal generative modeling
• Design new training objectives, loss functions, and evaluation methods optimizing for highly compute-efficient, low-latency generation
• Explore temporal modeling, controllability, and multimodal alignment
• Conduct empirical studies to understand scaling behavior and model performance
• Drive rapid experimentation across architectures and training strategies
• Analyze model behavior and identify opportunities for improvement
• Translate research insights into measurable product improvements

What makes you a great fit

• MS/PhD in ML, CS, or related field
• Strong publication record (NeurIPS, ICML, ICLR, etc. or equivalent work)
• Deep expertise in generative modeling (diffusion, autoregressive architectures, etc.)
• Deep understanding of transformers and modern multimodal systems
• Experience with large-scale training and empirical research, and optimizing models for real-time inference efficiency
• Strong experience working with audio representations and audio-visual datasets

Benefits

• Comprehensive medical, dental, and vision plans
• 401K with employer match
• Commuter Benefits
• Catered lunch multiple days per week
• Dinner stipend every night if you're working late and want a bite!
• Grubhub subscription
