Meta is seeking an experienced software engineer to join our Accelerator Solutions & Technologies group, supporting the development of Meta’s accelerators collective communications software library and optimizing distributed AI/ML workloads’ performance. This is an opportunity to work with a highly skilled engineering team, collaborating with a large set of cross-functional and international partners. Meta’s super-cluster AI/ML platforms offer the opportunity to work in an extremely dynamic environment, enabling core technologies deployed in some of the world’s largest scale clusters.Software Engineer, Accelerator Solutions & Technologies Responsibilities

• Contribute to our developer infrastructure, including simulation and HW emulation platforms, to enable performance measurement and optimization for Meta’s in-house accelerator programs.
• Understand and contribute to the collective communications library, intended to be deployed on Meta’s AI/ML superclusters.
• Support networking and compute hardware acceleration techniques to improve ML inference and training model performance.
• Perform architectural analysis to ensure system designs meet performance, scalability, and reliability requirements.
• Implement simulation models for Meta’s Accelerator ASICs, develop and analyze various scenarios to evaluate data center performance and identify potential improvements.
• Collaborate with architects and engineers to integrate simulation results into system design processes.
• Use instruction set simulators to define performant firmware for Meta's training/inference accelerators.
• Collaborate with hardware and firmware teams to ensure accurate modeling and simulation of accelerator functionalities.
• Analyze simulation results to guide firmware development and optimization efforts.

Minimum Qualifications

• Masters or doctorate degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience.
• 5+ years of programming experience in C++.
• 5+ years of programming experience in Python.
• Understanding of performance and benchmarking measurement and optimization on collective communications and distributed at-scale model training.
• Bachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience.

Preferred Qualifications

• Full-stack experience and understanding of AI/HPC systems, from hardware and infrastructure through the application layer, performance optimizations, including familiarity with relevant tools, libraries, and frameworks (e.g., NCCL, PyTorch, CUDA).
• Experience in one or more of the following ML domains: hardware accelerators, AI Infrastructure, and/or high performance compute (HPC), particularly pertaining to interconnect and collective.
• Knowledge of AI/HPC hardware requirements and specifications (e.g., configuring hardware components, GPU, memory, network for AI/HPC workloads).
• Understanding of the transport stack (e.g., RoCE), its constraints and performance measures and how transport considerations enable the collective communications stack.
• Experience with SystemC.
