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, effective 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.
