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.

• Contribute to internal LLVM forks or upstream
where applicable.

Requirements

Education:

BTech/BE/MTech/ME/MS/PhD in Computer Science, Computer Engineering,
Electronics/ECE, or a related field.

Technical Skills (Must haves):

​





• Solid 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.
