AI Compiler and Performance Engineer

Key Responsibilities

• Break down LLM and transformer workloads into fine-grained primitives tailored to our proprietary compute hardware.
• Design and implement IR transformations, graph optimizations, kernel lowering, and code generation for novel hardware architectures.
• Collaborate with ML researchers to co-design algorithmic optimizations that yield real end-to-end performance gains.
• Work closely with hardware architects to refine microarchitectural features, instruction sets, memory hierarchies, and execution models.
• Build performance models, profiling tools, and benchmarking frameworks to identify bottlenecks and guide design decisions.
• Prototype and validate improvements across the entire stack — from PyTorch/XLA-level passes to custom kernel implementations.
• Contribute to shaping the overall system architecture of a first-of-its-kind inference engine.

Required Qualifications

• BS/MS/PhD in Computer Science, Software Engineering, or a related field.
• Deep experience building compilers, optimizing kernels, or working with ML frameworks at a systems level.
• Strong proficiency in one or more programming languages such as Python and C++.
• Strong understanding of one or more of the following:
• LLM architectures and transformer internals
• MLIR, LLVM, XLA, TVM, Triton, or similar compiler infrastructures
• GPU/TPU/FPGA/ASIC compute models, memory hierarchies, and parallel execution
• Quantization, sparsity, or algorithmic optimization for deep learning
• Deep expertise on ML frameworks (e.g., PyTorch, TensorFlow, JAX) and understanding of ML model deployment challenges.
• Solid understanding of software engineering best practices, including data structures, algorithms, and testing.
• Thinking in terms of latency, cycles, memory bandwidth, and arithmetic intensity, not just algorithms.
• Excellent problem-solving abilities and a knack for tackling complex technical challenges.
• Excited to collaborate across ML, hardware, and software boundaries to invent something fundamentally new.
• Strong communication skills and a proven ability to collaborate effectively in a cross-functional team environment.
• Ability to thrive in a fast-paced, dynamic startup environment.
