• Develop and optimize Pallas kernels for large-scale model training and inference on TPU architectures

• Drive model optimization techniques including Mixture of Experts (MoE), tensor parallelism, pipeline parallelism, and other distributed training strategies

• Optimize first party models within wvTg'X native PyTorch stack, ensuring efficient integration with XLA compilation and TPU execution

• Identify and resolve complex technical challenges in model training efficiency, inference latency, and system reliability that require novel approaches

• Define and drive multi-quarter research roadmaps for TPU optimization, aligning project milestones with broader organizational goals

• Establish rigorous experimentation frameworks for performance benchmarking, including metric selection, profiling methodology, and data-driven optimization decisions

• Translate research findings into production-ready optimizations by collaborating with engineering teams on deployment pipelines and reliability at scale

• Communicate research findings and technical trade-offs clearly through publications, design documents, and presentations to both technical and non-technical audiences

• Mentor other researchers and engineers on TPU optimization techniques, providing structured feedback on technical direction and experimental rigor

Minimum Qualifications:

• Bachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience

• 8+ years of experience in machine learning systems, model optimization, or high-performance computing research

• Experience with TPU architecture and performance optimization, including profiling, kernel development, and memory management

• Experience with XLA compilation, graph optimization, and low-level performance tuning for accelerator hardware

• Experience developing and optimizing large-scale distributed training systems, including parallelism strategies such as data, tensor, and pipeline parallelism

• Experience with PyTorch and its integration with accelerator backends

• Experience communicating complex technical findings in writing, including technical reports, design documents, or peer-reviewed publications

Preferred Qualifications:

• Experience developing custom kernels using Pallas or similar kernel authoring frameworks for TPU or GPU

• Demonstrated track record of transitioning performance research into deployed systems used at significant scale

• PhD in Computer Science, Machine Learning, Computer Architecture, or a related technical field, or equivalent depth of research experience

• Publication record in systems for ML venues such as MLSys, OSDI, SOSP, or related AI conferences such as NeurIPS, ICML, or ICLR

• Experience with Mixture of Experts (MoE) architectures and their optimization for efficient training and inference

• Experience optimizing production-scale models with billions of parameters
