Job Description

Meta is seeking a Software Engineer to join our team. The ideal candidate is someone with experience working on maximizing performance of AI models on GPUs or custom silicon. This role involves applying these skills to solve some of the most crucial and exciting problems that exist on the web. The AI Applications Engineering team is dedicated to maximizing training and inference performance of Generative AI (GenAI) and Recommendation models on Meta's Training and Inference Accelerator (MTIA). We employ innovative optimization and parallelization strategies to maximize training throughput for the next generations of GenAI and recommendation models. Additionally, we work cross-functionally with many partner teams to ensure end-to-end performance of large-scale pre-training and inference, enabling us to deliver the next generation of AI experiences more quickly to our users.

Work cross-functionally to co-design models to maximize pre-training and inference efficiency

Applying and driving state-of-the-art optimization techniques to our latest large-scale AI workloads running on Meta’s fleet of accelerators including functional development and maintenance

Profiling, analyzing, debugging, and optimizing large-scale workloads on our next-generation training superclusters

Optimization of the underlying processes of the whole vertical stack, from kernels, framework, communication, and firmware to layers and hyperparameters

Set direction and goals for the team related to project impact, capacity, and developer efficiency

Lead large and complex technical efforts across many engineers and teams from zero to one

Minimum Qualifications

Bachelor’s degree in computer science or a related STEM field

Experience programming AI accelerators (e.g. GPUs, custom silicon etc.) using AI frameworks such as PyTorch or similar

Experience developing custom kernels and compiler infrastructure to improve performance using low-level programming models such as CUDA, OpenCL or similar

Minimum 6+ years of experience developing and optimizing performance in modern C/C++

Must obtain work authorization in the country of employment at the time of hire, and maintain ongoing work authorization during employment

Preferred Qualifications

Experience with training and validating large-scale AI models, including parallelising models across several accelerators

Understanding of multiprocessing, including race conditions and communications between processes

Experience of evaluating model performance, e.g., with profilers and tuning hyperparameters

Thorough understanding of model and data parallelisms such as FSDP, tensor parallelism, model parallelism, expert parallelism, etc

Demonstrated experience of the model life cycle from pre-training and post-training to inference, dataset splits and shuffling, metrics, especially for large language models

Experience of developing, optimizing and validating kernels on GPUs or other accelerators
