Compiler Engineer (Frontend) - San Jose, United States
Originally posted 9 February 2026 by the employer.
About the role
Persimmons is seeking a Compiler Engineer (Frontend) to optimize the Persimmons Compiler and convert AI models from popular machine learning frameworks into assembly code for accelerator hardware. In this role, you will provide technical leadership across the compiler team and implement scheduling algorithms for high-performance ML workloads.
What you'll do
- Design and build the compiler that converts AI models from popular ML frameworks into assembly code targeting accelerator hardware. - Develop and implement novel scheduling algorithms to optimize performance and execution. - Collaborate with cross-functional teams to design, test, and optimize hardware and software solutions. - Analyze and improve the efficiency, scalability, and performance of compiler and runtime systems. - Provide technical leadership across the compiler team, mentoring engineers in advanced compiler techniques.
What you'll need
- 6+ years of experience in compiler development, with deep knowledge of modern compiler frameworks such as LLVM, MLIR, TVM, XLA, or IREE. - Proven track record of leading compiler or runtime systems projects from design through deployment. - Experience processing models from frameworks including PyTorch, TensorFlow, or JAX, along with familiarity with architectures such as transformers and diffusion models. - Familiarity with auto-scheduling and program synthesis techniques for high-performance ML kernels (such as TVM, Halide, or Ansor), or experience with hardware-aware scheduling techniques. - Familiarity with hardware architectures including memory hierarchies, systolic arrays, DMA engines, and GPU-style parallelism. - Strong C++ and Python programming skills, including practical knowledge working with large code bases and multithreaded debugging. - BS, MS, or PhD degree in Computer Science, Computer Engineering, or a related field (or equivalent experience).
