Software Engineer, Agents

Mirage is an AI-native video platform that intelligently orchestrates production and editing through natural language. This role focuses on designing and building agentic systems that power creative workflows for short-form video. Software Engineers on the agents team work across product, machine-learning, and systems engineering — owning meaningful problems end-to-end and helping define how our agents are built and deployed across the product.

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

Requirements

5+ years of professional industry experience; A 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; Able to operate effectively in an extremely fast-paced environment and scope and deliver projects end-to-end

Nice to have

You have worked with multi-agent architectures; You have experience fine-tuning LLMs for specific use cases; You have a pulse on where generative media and agentic AI technology is going; You are grounded, collaborative, and willing to do whatever it takes to help the team win; You have been a startup founder or an early engineer at one
