Job summary

Mirage is building an AI-native video platform that orchestrates production and editing via natural language. You will design and ship agentic systems enabling creative workflows, with agents taking actions on user behalf while exploring new models and production-ready approaches.

As a senior/Staff+ engineer, you’ll work across product, ML, and systems to own end-to-end problems and help deploy agents at scale in NYC. Join an interdisciplinary team solving hard challenges in generative media.

Qualifications

• 5+ years of professional industry experience.
• Track record of designing and developing ML systems or agentic pipelines in production.
• Deep experience with context engineering: RAG systems, token optimization, context management at scale.
• Experience building evaluation systems and agentic infrastructure (context gathering, tool selection, multi-step planning).
• Exceptional problem solving fundamentals and ability to learn quickly in a rapidly evolving space.

Responsibilities

• Build and ship end-to-end agentic systems that meaningfully improve creative workflows, balancing quality, performance, and reliability.
• Design agent architectures — how agents gather context, plan, select tools, and execute creative tasks reliably at scale.
• Integrate state-of-the-art models, combining internal research and external capabilities to power new agent experiences.
• Measure and improve agent quality in production, using experimentation, evaluation frameworks, and real-world feedback to guide iteration.
