Software Engineer, AI Platform

This role can be based in Mountain View CA San Francisco CA or Bellevue WA.

Join us to push the boundaries of scaling large models together. The team is responsible for scaling LinkedIns AI model training feature engineering and serving with hundreds of billions of parameters models and large scale feature engineering infra for all AI use cases from recommendation models large language models to computer vision models. We optimize performance across algorithms AI frameworks data infra compute software and hardware to harness the power of our GPU fleet with thousands of latest GPU cards. The team also works closely with the open source community and has many open source committers (TensorFlow Horovod Ray vLLM Hugginface DeepSpeed etc.) in the team. Additionally this team focussed on technologies like LLMs GNNs Incremental Learning Online Learning and Serving performance optimizations across billions of user queries.

Model Training Infrastructure: As an engineer on the AI Training Infra team you will play a crucial role in building the next-gen training infrastructure to power AI use cases. You will design and implement high performance data I/O work with open source teams to identify and resolve issues in popular libraries like Huggingface Horovod and PyTorch enable distributed training over 100s of billions of parameter models debug and optimize deep learning training and provide advanced support for internal AI teams in areas like model parallelism tensor parallelism Zero etc. Finally you will assist in and guide the development of containerized pipeline orchestration infrastructure including developing and distributing stable base container images providing advanced profiling and observability and updating internally maintained versions of deep learning frameworks and their companion libraries like Tensorflow PyTorch DeepSpeed GNNs Flash Attention. PyTorch Lightning and more and more.

Feature Engineering: this team shapes the future of AI with the state-of-the-art Feature Platform which empowers AI Users to effortlessly create compute store consume monitor and govern features within online offline and nearline environments optimizing the process for model training and serving. As an engineer in the team you will explore and innovate within the online offline and nearline spaces at scale (millions of QPS multi terabytes of data etc) developing and refining the infrastructure necessary to transform raw data into valuable feature insights. Utilizing leading open-source technologies like Spark Beam and Flink and more you will play a crucial role in processing and structuring feature data ensuring its most optimal storage in the Feature Store and serving feature data with high performance.

Model Serving Infrastructure: this team builds low latency high performance applications serving very large & complex models across LLM and Personalization models. As an engineer you will build compute efficient infra on top of native cloud enable GPU based inference for a large variety of use cases cuda level optimizations for high performance enable on-device and online training. Challenges include scale (10s of thousands of QPS multiple terabytes of data billions of model parameters) agility (experiment with hundreds of new ML models per quarter using thousands of features) and enabling GPU inference at scale.

ML Ops: The MLOps and Experimentation team is responsible for the infrastructure that runs MLOps and experimentation systems across LinkedIn. From Ramping to Observability this org powers the AI products that define LinkedIn. This team inside MLOps is responsible for AI Metadata Observability Orchestration Ramping and Experimentation for all models; building tools that enable our product and infrastructure engineers to optimize their models and deliver the best performance possible.

As a Software Engineer you will have first-hand opportunities to advance one of the most scalable AI platforms in the world. At the same time you will work together with our talented teams of researchers and engineers to build your career and your personal brand in the AI industry.
