Job Description:
The Role:
Join the SiFive AI/ML Software Team to build the high-performance stack for Next-Gen AI. We are seeking engineers to optimize and deploy LLMs and Generative AI models on RISC-V architectures, spanning from compiler infrastructure to distributed runtime systems.
Responsibilities:
Compiler Infrastructure: Develop and maintain MLIR/IREE/Triton compiler stacks; optimize end-to-end (e2e) LLM performance and contribute to relevant open-source communities.
Runtime Systems: Design and implement single/multi-device scheduling and memory management layers; define hardware-software interfaces for high-throughput AI workloads.
Model Infrastructure: Implement model sharding and distribution strategies; lead the integration between high-level frameworks (e.g., PyTorch) and hardware backends.
Performance Optimization: Analyze and profile AI models to identify bottlenecks; develop high-performance kernels leveraging RISC-V Vector (RVV) and custom ISA extensions.
Co-design: Collaborate with hardware architects to influence the design of future AI accelerators and microarchitectures.
Requirements
Education: Master’s or PhD in Computer Science, Applied Mathematics, or a related field.
Programming: Strong proficiency in C++ and Python.
Domain Expertise: Solid understanding of AI/ML models (LLMs, Diffusion, Transformers) and their deployment challenges.
Technical Track (One or more of the following):
Experience with compiler frameworks like MLIR, IREE, LLVM, or Triton.
Background in system programming, memory management, or multi-device orchestration.
Knowledge of distributed computing, model parallelism, or tensor sharding.
Preferred Qualifications
Experience with AI/ML frameworks like PyTorch, ONNX Runtime, or TF/TFLite.
Familiarity with distributed training/inference and collective communications.
Active contributions to open-source AI/ML or compiler projects.
Experience in low-level performance tuning or MLPerf benchmarking.
