Staff LLVM-Ripple Compiler Engineer

Qualcomm; San Diego (CA); On-site; USD 141,000 - 211,000; Full time

Job summary

Qualcomm Technologies, Inc. in California seeks a Staff Engineer to drive LLVM‑Ripple development, its compiler toolchain, and the ecosystem that enables massively parallel application development on Snapdragon platforms.

You will design, develop, optimize, and maintain compiler components, parallel runtimes, and developer‑facing features, collaborating with architecture teams and application engineers to evolve Ripple and achieve performance portability across heterogeneous compute.

Qualifications

• Bachelor’s degree in Computer Engineering, Computer Science, Electrical Engineering, or related field with 8+ years of software engineering experience.
• Master’s degree with 6+ years, or PhD with 3+ years.
• Strong experience with LLVM development (IR transformations, back‑end, code generation) and compiler toolchain design.
• Expertise in parallel programming models (CUDA, OpenCL, OpenMP, SIMD/SIMT).
• Proficiency in C/C++ and modern compiler engineering practices.
• Experience with runtime systems, concurrency, or parallel execution models.

Responsibilities

• Lead design and development of LLVM‑Ripple compiler components, including front‑end extensions, middle‑end optimizations, back‑end code generation, and tooling support.
• Architect and implement improvements to parallel runtimes, including scheduling, memory models, synchronization, and heterogeneous workloads targeting Snapdragon processors.
• Define and evolve programming abstractions to improve developer experience for highly parallel and heterogeneous applications.
• Collaborate with hardware architecture teams to model and expose new parallel features, SIMD/SIMT execution models, and accelerator capabilities through compiler and runtime interfaces.
• Drive performance analysis, benchmarking, and optimization across the full Ripple ecosystem: compiler, runtime, libraries, and application workloads.
• Deliver high‑quality, maintainable code and documentation; contribute upstream to LLVM and Ripple where appropriate.
