About Luma AI
Luma's mission is to build multimodal AI to expand human imagination and capabilities. We believe that multimodality is critical for intelligence. To go beyond language models and build more aware, capable and useful systems, the next step function change will come from vision. So we are working on training and scaling up multimodal foundation models for systems that can see and understand, show and explain, and eventually interact with our world to effect change.

About the Role
The Performance Optimization team at Luma is dedicated to maximizing the efficiency and performance of our AI models. Working closely with both research and engineering teams, this group ensures that our cutting-edge multimodal models can be trained efficiently and deployed at scale while maintaining the highest quality standards.

Responsibilities
  • Profile and optimize GPU/CPU/Accelerator code for maximum utilization and minimal latency
  • Write high-performance PyTorch, Triton, CUDA, deferring to custom PyTorch operations if necessary
  • Develop fused kernels and leverage tensor cores and modern hardware features for optimal hardware utilization on different hardware platforms
  • Optimize model architectures and implementations for distributed multi-node production deployment
  • Build performance monitoring and analysis tools and automation
  • Research and implement cutting-edge optimization techniques for transformer model

Experience
  • Expert-level proficiency in Triton/CUDA programming and GPU optimization
  • Strong PyTorch skills
  • Experience with PyTorch kernel development and custom operations
  • Proficiency with profiling tools (NVIDIA Nsight, torch profiler, custom tooling)
  • Deep understanding of transformer architectures and attention mechanisms
  • (Preferred) Experience with compilers/exporters such as torch.compile, TensorRT, ONNX, XLA
  • (Preferred) Experience optimizing inference workloads for latency and throughput
  • (Preferred) Experience with Triton compiler and kernel fusion techniques
  • (Preferred) Knowledge of warp-level intrinsics and advanced CUDA optimization

What you need to know about the Los Angeles Tech Scene

Los Angeles is a global leader in entertainment, so it’s no surprise that many of the biggest players in streaming, digital media and game development call the city home. But the city boasts plenty of non-entertainment innovation as well, with tech companies spanning verticals like AI, fintech, e-commerce and biotech. With major universities like Caltech, UCLA, USC and the nearby UC Irvine, the city has a steady supply of top-flight tech and engineering talent — not counting the graduates flocking to Los Angeles from across the world to enjoy its beaches, culture and year-round temperate climate.

Key Facts About Los Angeles Tech

  • Number of Tech Workers: 375,800; 5.5% of overall workforce (2024 CompTIA survey)
  • Major Tech Employers: Snap, Netflix, SpaceX, Disney, Google
  • Key Industries: Artificial intelligence, adtech, media, software, game development
  • Funding Landscape: $11.6 billion in venture capital funding in 2024 (Pitchbook)
  • Notable Investors: Strong Ventures, Fifth Wall, Upfront Ventures, Mucker Capital, Kittyhawk Ventures
  • Research Centers and Universities: California Institute of Technology, UCLA, University of Southern California, UC Irvine, Pepperdine, California Institute for Immunology and Immunotherapy, Center for Quantum Science and Engineering
