Product Engineer | Frontend Architecture

The Opportunity Luma AI is defining the future of creative tools through multimodal foundational models. We are one of the few companies in the world with the resources to compete at the frontier of AI research while retaining a lean engineering structure. This ensures that every engineer on our team has immense leverage and direct access to the core technology.

Where You Come In You will serve as a technical authority for our frontend systems, architecting the client-side infrastructure that powers massive-scale generative media. This is a role for a systems thinker who applies engineering rigor to the browser, ensuring that our application remains performant and reliable while handling heavy media assets and asynchronous agentic workflows.

What You Will Build The Application Engine: You will architect the core state management and data flow systems that coordinate between our generative models and the client, handling complex optimistic updates and race conditions. Performance at Scale: You will build the infrastructure to support high-fidelity video and 3D rendering in the browser, optimizing the critical rendering path to ensure low latency for millions of users. Scalable Foundations: You will define the technical strategy for our component architecture, establishing patterns that allow the product team to ship rapidly without accruing technical debt.

The Profile We Are Looking For Architectural Authority: You have a track record of designing complex frontend systems from first principles, demonstrating the judgment to navigate trade-offs between speed, reliability, and scale. Systems Generalist: While your focus is the frontend, you understand the full stack and can design API contracts that optimize the efficiency of the client-server relationship. Deep Fluency: You are an expert in the internals of React and TypeScript, with the ability to debug complex performance bottlenecks and memory leaks in media-heavy applications.
