Job Description

The Role:

As an AI Compiler Engineer, you will be responsible for designing, developing, and optimizing the AI compiler toolchain that bridges high-level machine learning frameworks and Openchip’s AI hardware accelerators (RISC-V). You will work closely with software, hardware, and AI engineers to enable efficient inference execution of best-in-class GenAI LLMs, optimizing code generation and advance compiler infrastructure.

Your work will directly influence performance and scalability across Openchip’s AI inference stack.

Key Responsibilities:

· Design, implement, and maintain compiler components for AI inference workloads, focusing on graph lowering, optimization, and code generation (from frameworks like PyTorch, TensorFlow, or ONNX to hardware).

· Collaborate with hardware teams to leverage hardware features, maximizing performance.

· Contribute to open-source compiler ecosystems (e.g., LLVM, MLIR, TVM, XLA, IREE).

· Profile, debug and optimize model execution to maximize throughput and minimize latency together with energy efficiency.

· Enable validation on prototype silicon or simulators or real hardware.

Required Qualifications:

· Master’s or PhD in Computer Science, Electrical/Computer Engineering, or related field.

· 3+ years of experience in compiler development for AI/ML, GPU, DSP, or custom accelerators.

· Proven expertise with MLIR, LLVM, or similar compiler infrastructures.

· Strong programming skills in C++ and Python.

· Solid understanding of neural network computation graphs, linear algebra, and AI inference frameworks.

· Experience in code generation, optimization passes, and runtime integration.

Technical skills:

· MLIR / LLVM / IREE / TVM compiler development

· Model formats: ONNX, TensorFlow, PyTorch

· Low-level optimization (SIMD, vectorization, scheduling, data-tiling)

· Familiarity with hardware accelerators (GPU, NPU, TPU, DSP)

· Software profiling and performance analysis tools

· Git, CMake, CI/CD workflows

Nice to have:

· Experience with RISC-V architecture or AI accelerators

· Contributions to open-source MLIR or compiler projects

· Knowledge of quantization, mixed precision, and graph optimization techniques

· Exposure to system software, runtime APIs, or driver-level integration

· Background in heterogeneous computing and parallel processing

Soft Skills:

· Passion for innovation and cutting-edge AI technologies

· Strong collaboration and cross-functional communication skills

· Autonomy, curiosity, and a growth mindset

· Problem-solving attitude with attention to detail

· Ability to thrive in a fast-paced, startup-like environment
