## Job description

Mirage is an AI video company focused on making creation dramatically easier. Our team tackles some of the hardest creative and technical challenges in generative media.

We get to rethink how people collaborate with AI that can actually do creative work with them—defining entirely new interaction paradigms for AI-native video tools. We make that possible by building multimodal agents that turn creative direction into edits, rendering engines that composite multiple layers of video and graphics, and generative video models trained from the ground up that create new media when needed.

All of this comes together in Captions, our creative workspace for generating, editing, and designing video. The technology behind Captions is now available more broadly: Tesseract gives any AI agent native video-editing capabilities, while developers can integrate our models into their own products through APIs.

## About the Role

Mirage is seeking an ML Engineer to push the boundaries of large language models for multimodal creative tasks. You'll develop new approaches for building and extending agentic systems that understand and operate over complex, real-world data, particularly video. This role focuses on advancing agent capabilities, improving reasoning and control, and enabling new forms of interaction between language models and time-based media.

## Responsibilities

- Design and build end-to-end agentic systems for creative tasks
- Develop novel approaches for training and adapting the large language models that power these agents
- Design new objectives, datasets, and fine-tuning strategies to improve agent behavior and reliability
- Explore multimodal reasoning and structured generation for creative control
- Run systematic experiments to evaluate and improve agent performance in real-world tasks
- Design evaluation frameworks for agentic workflows in video analysis and editing
- Analyze failure modes across the full agent loop (planning, tool use, execution) and iterate on improvements

What makes you a great fit

- BS/MS/PhD in CS, ML, or related field
- Strong track record building production ML systems or agentic pipelines
- Deep understanding of transformers and modern LLM techniques
- Experience with fine-tuning, alignment, or post-training methods, especially for adapting models to generate structured outputs or drive tool use
- Comfort owning the full stack, from model-level experiments to deployed agent systems
- Strong experimental rigor and good taste for what makes agents actually work in practice

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
- Health & Wellness Perks
- Multiple team offsites per year with team events every month
- Generous PTO policy
