Job Description

Want to enable the next generation of high-performance CPUs from Qualcomm? Let’s talk. We support the LLVM toolchain for Qualcomm’s custom CPUs for multiple platforms. As a member of a focused group with experience in compiler development and performance analysis, you will work closely with our CPU hardware team and other groups. In addition to the compilation workflow from front-end to back-end, we also analyze and improve the performance of libraries within LLVM, as well as libraries for cryptography, compression, memory allocation, atomics, etc. Our top priority is to use our knowledge of Qualcomm’s micro-architecture to develop the highest performance solutions. We do open-source development, and you will engage with upstream communities to align with software projects that our customers and partners are dependent on and participate in. You will have an opportunity to engage with key end-users and third parties on enablement and tuning high priority applications and solutions.
Must have:
  • Research, design, develop, and enhance different components of the compiler
  • Analyze performance, code size and other metrics to identify compiler improvements and/or library improvements
  • Translate customer requirements into opportunities for differentiation using our hardware.
  • Work closely with silicon and software performance teams to model and predict leading application performance and areas for optimization
  • Analyze and identify system level integration issues, interface with the software development, integration and test teams
  • Develop and execute benchmark and test scenarios for compilers and libraries
  • Leverages advanced Software knowledge and experience to design, develop, create, modify, and validate critical embedded and cloud edge software, applications, and/or specialized utility programs.
  • Analyzes user needs, software requirements, and time and cost constraints to design and customize sophisticated software for optimal operational efficiency.
  • Designs and implements software sub-systems for complex, large-scale products and systems.
  • Leads design, coding, and testing efforts to ensure that projects are completed to specifications and schedules.
  • Performs highly complex code reviews and regression tests as well as triages and fixes issues to ensure the quality of code.
  • Collaborates with individuals outside the software function (e.g., Hardware, Systems, and Test engineers) to increase leverage and design solutions that work with other components of a specific project.
  • Writes detailed technical documentation for highly complex Software projects; reviews technical documentation for junior engineers.
Good to have:
  • Knowledge and experience in compiler frameworks such as LLVM or gcc
  • Programming in C/C++ and assembly languages
  • Professional experience with compiler development
  • Experience with LLVM
  • Knowledge of instruction sets and computer architectures - pipeline structure, hazards, cache, memory organization, etc.
  • Working knowledge of system software tools such as assemblers, linkers, debuggers and experience using them
  • Strong communication and interpersonal skills
