We
are looking for an experienced LLVM Backend Engineer to design and implement
backend components of the compiler toolchain. The role focuses on building and
optimizing the code generation flow targeting a custom or existing hardware
architecture. The candidate will work on LLVM IR transformations, instruction
selection, and target-specific optimizations to deliver high-performance,
efficient compiled code.
Responsibilities:
• Develop and maintain the LLVM backend for a
custom or existing target architecture.
• Implement and extend instruction selection,
register allocation, scheduling, and code emission.
• Design and implement IR-level optimization passes
to improve performance, memory efficiency, and code quality.
• Work on LLVM middle-end transformations and
optimizations.
• Analyze and tune generated assembly/code quality
for performance bottlenecks.
• Collaborate with hardware teams to ensure
architectural features are fully leveraged by the compiler backend.
Requirements
Education:
• Strong C/C++ programming skills and solid
understanding of compiler fundamentals.
• Hands-on experience with LLVM, LLVM IR, and
backend/code-generation components.
• Understanding of instruction selection, register
allocation, instruction scheduling, and code emission.
• Experience with compiler optimizations and
performance/code-quality analysis.
Need to have (Can be bridged):
• Experience developing or modifying LLVM backend
components for a target architecture.
• Knowledge of IR-level and middle-end
transformations and optimization passes.
• Ability to analyze generated assembly and
identify performance bottlenecks.
Good to have (Not essential):
• Experience with custom hardware architectures,
accelerators, CPU/GPU/DSP/FPGA targets, or domain-specific architectures.
• Experience contributing to upstream LLVM or
maintaining an internal LLVM fork.
• Familiarity with compiler testing, benchmarking,
and performance tuning workflows.
Preferred Qualifications (Optional):
• Experience collaborating closely with
hardware/architecture teams and translating architectural features into
compiler support.
