LLVM Back-end Engineer

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):

• 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.
