About Luma AI A new class of intelligence is emerging systems that understand and generate the world across video images audio and language Building multimodal AGI is not just a modeling challenge It is an infrastructure challenge at the edge of what hardware software and organizations can support At Luma we operate rapidly scaling 10k GPU fleets pushing utilization throughput and reliability hard enough that yesterdays solutions break regularly Researchers depend on this infrastructure to move the frontier forward Customers depend on it to power real creative work Many companies run accelerators Very few sit directly next to the teams inventing the models that redefine what those accelerators must do At Luma improvements to scheduling efficiency and reliability immediately translate into faster research iteration and entirely new product capabilities We are still early The playbook is still being written A single exceptional engineer can reshape how the company operates Where You Come In Our Infrastructure Engineering team is a systems engineering group with companylevel responsibility At Luma reliability engineers work directly with the researchers and products pushing the limits of multimodal intelligence We operate close to the metal Kernels Containers Schedulers Networking Storage GPU behavior But we are also responsible for something bigger Turning deep systems knowledge into repeatable scalable reliability for the entire company We are hiring a leader who will define that direction You will be a technical authority an organizational force multiplier and a magnet for other great engineers What Youll Own Reliability of the Frontier Architect and operate large heterogeneous GPU environments under extreme demand Improve utilization and performance where small gains materially change company outcomes Resolve failures that span hardware OS runtimes and orchestration Eliminate entire classes of instability Build mechanisms that make heroics unnecessary Scaling Training amp Inference Define how infrastructure and workloads evolve as cluster size and concurrency grow Design scheduling placement and resource management approaches for increasingly complex jobs Work directly with research to build the systems required for new model capabilities Ensure inference platforms scale rapidly without sacrificing reliability or latency Anticipate where todays abstractions will fail and redesign ahead of them Building the Organization Hire and develop exceptional systems and reliability engineers Set the bar for technical depth judgment and production ownership Shape architecture early through strong partnerships with research and product Translate reliability constraints into longterm platform strategy Who You Are Required Deep expertise in Linux and distributed systems Experience operating GPU accelerator clusters in real production environments Strong fluency in Kubernetes and modern opensource infrastructure Comfortable debugging across hardware kernel runtime orchestration You understand how systems behave under contention and at scale You write code and build automation You think in bottlenecks failure modes and tradeoffs Engineers trust your judgment especially when things break Important This role requires comfort operating close to upstream and close to the metal If most of your experience has been inside highly abstracted internal platforms where others owned the underlying machinery this is unlikely to be a match Leadership Expectations You raise reliability standards across the company You influence product and research architecture early You build strong partnerships not ticket queues You attract and level up exceptional engineers You are curious how models use infrastructure because improving systems expands what becomes possible Why This Role Is Special Most infrastructure roles optimize mature systems This one helps define how reliability works for a new generation of AI infrastructure The decisions you make here will influence How research progresses How products scale How customers trust us And how the engineering organization grows If you want to build the reliability foundations of a company operating at the technological frontier we should talk
