Mirage is the leading AI short‑form video company. We’re building full‑stack foundation models and products that redefine video creation, production and editing. 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.
All roles will require you to be in‑person at our NYC HQ (located in Union Square).
We do not work with third‑party recruiting agencies; please do not contact us.
About the Role and Team Captions seeks an exceptional Research Engineer (MOTS) to drive innovation in training data infrastructure. You'll conduct research on and develop sophisticated distributed training workflows and optimized data processing systems for massive video and multimodal datasets. Beyond pure performance, you'll develop deep insight into our data to maximize training effectiveness. As an early member of our ML Research team, you'll build foundational systems that directly impact our ability to train models powering video and multimodal creation for millions of users.
You’ll work directly alongside our research and engineering teams in our NYC office. We've intentionally built a culture where infrastructure and data work is highly valued — your success will be measured by the reliability and performance of our systems, not by your ability to navigate politics. We’re a team that loves diving deep into technical problems and emerging with practical solutions.
Our team values
Quick iteration and practical solutions.
Open discussion of technical approaches.
Direct access to decision makers.
Regular sharing of learnings, results, and iterative work.
Key Responsibilities Infrastructure Development
Build performant pipelines for processing video and multimodal training data at scale.
Design distributed systems that scale seamlessly with our rapidly growing video and multimodal datasets.

Implement comprehensive telemetry for video processing and training pipelines.
Core Systems Development
Create foundation data processing systems that intelligently cache and reuse expensive computations across the training pipeline.
Build robust data validation and quality measurement systems for video and multimodal content.
Design systems for data versioning and reproducing complex multimodal training runs.
Develop efficient storage and compute patterns for high‑dimensional data and learned representations.
System Optimization
Own and improve end‑to‑end training pipeline performance.
Build systems for efficient storage and retrieval of video training data.
Build frameworks for systematic data and model quality improvement.
Develop infrastructure supporting fast research iteration cycles.
Build tools and systems for deep understanding of our training data characteristics.
Research & Product Impact
Build infrastructure enabling rapid testing of research hypotheses.
Create systems for incorporating user feedback into training workflows.
Design measurement frameworks that connect model improvements to user outcomes.
Enable systematic experimentation with direct user feedback loops.
Requirements Technical Background
