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 professional 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.

About the Role
We’re looking for an experienced software engineer to help design and build our next-generation, cross-platform rendering engine for video and graphics. This is a foundational, long-term effort: you’ll work on core systems that power how media is rendered, transformed, and composed across platforms. The work spans low-level rendering, media processing, and systems design. You’ll help define the architecture, make fundamental technical decisions, and build infrastructure that will support increasingly sophisticated creative workflows.
We don’t use hierarchical titles or levels internally, but are currently hiring engineers who have operated at senior or staff+ scope.
Responsibilities
Design and build a high-performance, cross-platform rendering engine for video and graphics, capable of powering complex creative workflows
Own core media and rendering systems, including composition, transforms, effects, and execution pipelines
Make foundational architectural decisions around engine structure, language choice, performance tradeoffs, and long-term maintainability
Optimize for performance, correctness, and scalability, balancing throughput, latency, and resource efficiency in production environments
Collaborate with product, AI, and client teams to ensure the engine supports evolving creative and product requirements
Build abstractions and APIs that enable other teams to build on top of the engine safely and efficiently
What makes you a great fit
Strong experience building performance-critical systems in production
Deep understanding of graphics, media, or rendering pipelines, such as video processing, real-time or offline rendering, or GPU-accelerated systems
Proficiency in one or more systems programming languages (e.g., C++, Rust, or similar), with the ability to reason about memory, concurrency, and performance
Strong computer science fundamentals, especially in algorithms, data structures, and systems design
Experience owning large, complex projects over long time horizons
Comfortable operating in ambiguous problem spaces and making high-leverage technical decisions
Even better if…
You’ve worked on rendering engines, media pipelines, or graphics infrastructure used at scale
You have experience with video codecs, media formats, or GPU compute
You’ve built or maintained cross-platform engines or shared core systems
You enjoy close collaboration and working on deep technical problems
Comprehensive medical, dental, and vision plans
