Technical Artist Job at Luma AI (Palo Alto)

Job Description

This is a rare opportunity to sit at the intersection of frontier research and creative application. As a Technical Artist on the Applied team, you will be the bridge that takes our underlying foundation models and makes them production-ready. You won't just be using tools; you will be defining the workflows, fine-tuning strategies, and aesthetic benchmarks that turn raw model capabilities into magical, controllable experiences for millions of creators. This is a 0-to-1 opportunity to shape the 'feel' of Luma's next generation of AI.

Architect and Build Pipelines: Design and implement robust ComfyUI-style pipelines to productionize our models
Own Model Fine-Tuning: Develop and implement LoRA-based fine-tuning strategies to enhance model controllability
Bridge Research and Design: Collaborate closely with the Research and Design teams to evaluate early model versions
Drive Model Improvement: Take ownership of identifying model deficiencies and implementing fine-tuning solutions or data enhancements
QA for Aesthetics: Work with the Data team to ensure final models meet exceptionally high aesthetic quality standards
Prototyping: Rapidly prototype new creative workflows and controllability features to test new research opportunities

Requirements

Demonstrable experience with Visual GenAI, either as a creator, fine-tuner, researcher, or engineer
Strong generalist engineering skills with proficiency in Python
Deep experience with open-source generative AI tools such as ComfyUI, Automatic1111, Kohya, or similar frameworks
A hobbyist or professional background in art/design leading to a deep understanding of aesthetics and the ability to articulate visual choices using standard artistic language
Experience with Low-Rank Adaptation (LoRA) techniques and other methods for efficient model fine-tuning
Exceptionally motivated and passionate about building amazing models, with a 'high agency' drive to solve problems independently

Nice to have

Active contributions to the open-source Generative AI community (custom nodes, workflows, etc.)
Experience shipping tools that sit between R&D and production
