About the role

We believe that multimodality is critical for intelligence.
You will be a foundational member of the team, designing the critical systems that allow us to train and serve next-generation AI to millions of users.
You will have massive ownership to: Architect end-to-end model serving pipelines and integrate new model architectures from our research team into our core, high-throughput inference engine.

Build robust and sophisticated scheduling systems to manage jobs based on cluster availability and user priority, ensuring we optimally leverage thousands of expensive GPU resources.
Design and implement dynamic, traffic-based systems for hotswapping models on our GPU workers to maximize fleet efficiency and meet product SLOs.
Own the end-to-end CI/CD pipelines, including creating a resilient artifact store to manage all model checkpoints across multiple versions and providers.
Develop and maintain user-friendly APIs and interaction patterns that empower our product and research teams to ship groundbreaking features at high velocity.
Manage and optimize our complex inference workloads at scale, operating across multiple clusters and hardware providers.
About Luma AI Luma's mission is to build multimodal AI to expand human imagination and capabilities.
Where You Come In This is a rare opportunity to build the foundational infrastructure that powers our large-scale multimodal models.

You are a non-negotiable fit if you have: 5+ years of professional engineering experience with deep, hands-on proficiency in Python and complex distributed systems architecture.
Deep expertise in our core infrastructure stack: Linux, Docker, and Kubernetes.
Strong experience with Redis, S3-compatible storage, and public cloud platforms (AWS).
Experience with modern networking stacks, including RDMA (RoCE, Infiniband, NVLink).
Familiarity with FFmpeg and multimedia processing pipelines.
5+ years of professional engineering experience with deep, hands-on proficiency in Python and complex distributed systems architecture.
Experience with high-performance, large-scale ML systems (managing >100 GPUs).

To go beyond language models and build more aware, capable and useful systems, the next step function change will come from vision.
What Sets You Apart (Bonus

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.
We believe that reliable, high-performance infrastructure is the single biggest differentiating factor between success and failure in achieving our mission.
