Compiler Performance Engineer

The Compiler Engineering team within Intel's Data Center Group is seeking talented and passionate compiler engineers to help shape the future of software development.

At Intel, we are building next-generation software technologies that unlock the full potential of heterogeneous computing. Our compiler technologies enable developers to efficiently leverage CPUs, GPUs, and accelerators through high-performance, portable software. Our mission is to design, innovate, and deliver industry-leading compilers and development tools that maximize hardware performance across Intel platforms. By advancing performance, scalability, reliability, and developer productivity, we empower AI, HPC, and other compute-intensive workloads while maintaining a strong commitment to open-source collaboration and innovation.

Our team develops LLVM-based compiler technologies for C, C++, SYCL, Triton, MLIR, domain-specific languages (DSLs), and Fortran, targeting Intel CPUs and GPUs. We work across the entire compiler stack, including language front ends, intermediate representations, optimization frameworks, code generation, debug information, runtimes, offload support, quality engineering, and developer tooling.

This role provides exceptional opportunities for technical growth and career development through hands-on work with cutting-edge compiler technologies, mentorship from experienced engineers and technical leaders, and collaboration with world-class engineering teams across the globe.

As part of the compiler performance and optimization team, you will gain firsthand experience in the technologies that transform source code into highly optimized machine code. Your responsibilities will include:

• →Analyzing performance issues in compiler-generated code and identifying root causes within optimization and code generation stages.
• →Measuring and tuning application performance on Intel CPUs and GPUs while tracking regressions and identifying optimization opportunities.
• →Designing and implementing automated testing solutions to continuously monitor compiler performance and quality.
• →Bridging Intel hardware and compiler capabilities with AI and HPC software ecosystems, including PyTorch, inference frameworks, and machine learning workloads.
• →Contributing to open-source compiler communities through issue reporting, patch development, code reviews, and technical discussions.
• →Developing and enhancing compiler components, including optimization passes, code generation features, runtime systems, and offload technologies under the guidance of senior engineers.
• →Building expertise in specialized areas such as compiler optimizations, backend code generation, heterogeneous computing, offload compilation, or workload performance analysis.

As a software engineer on our team, you will collaborate with a diverse, global group of engineers and have the opportunity to influence the future of compiler technology, developer tools, and high-performance computing software.
