Tensor parallelism Jobs

Luma is seeking a Research Scientist/Engineer to build the systems that enable reinforcement learning (RL) at a frontier scale. This role involves coupling policy optimization with large fleets of inference workers, agentic environments, and reward/verification systems to translate model behavior into learning signals. RL is crucial for Luma's models to evolve from capable to useful. This is a full-loop systems problem encompassing training, rollout generation, environment execution, and reward computation across thousands of GPUs, requiring speed, stability, and correctness. The ideal candidate has experience with post-training LLMs using RL, building environments and verifiers, and debugging large-scale asynchronous rollout pipelines.

LanceDB is seeking an AI Research Engineer to collaborate with their research team on open-ended research projects. The role focuses on end-to-end training flows across various AI domains, demonstrating how LanceDB can accelerate research. This is a unique opportunity to pursue research interests as an engineer, significantly impacting product development and raising awareness of LanceDB's capabilities.
