Job description

Performance Modeling Software Architect, Platform Architecture

You will be tasked with ensuring Apple's ability to produce high quality, timely data to drive world class hardware designs. You will collaborate with engineers across the organization to translate design space studies into well written software models. You will develop your ability to transform the hardware execution model into high-performance C++. You will be involved with the full life-cycle of performance modeling, from early architectural exploration to post-silicon correlation. Last, but not least, you'll be expected to pay close attention to the performance, maintainability, and flexibility of the simulator, making sure hardware architects can quickly iterate on experiments.

Responsibilities

• Appreciate the good parts of C++, and leveraging the language to maximize the utility of our software models
• Develop APIs that can be used by non-expert C++ developers
• Train AI agents and non-expert C++ developers on idiomatic code and methods
• Help ensure our codebase is structured for effective use with AI-assisted development tools
• Write clear, self-documenting code with consistent conventions, meaningful naming, and well-organized modules
• Learn about the state of the art in SoC IP and chip-level architecture
• Work on data analysis pipelines, visualization methodologies, continuous regression testing
• Careful analysis and presentation of simulation results

Requirements

• MS or PhD in CS, EE or related field
• 20+ years of relevant experience
• Experience with multi-paradigm software development in C++
• Experience with multi-language programming environments, and selecting the right tool or language for the job
• Experience with compiler explorer and understanding the transformations the compiler is performing on your code
• Experience thinking about code as something that will be read by both humans and machines, and instituting conventions, structure, and documentation that make a codebase tractable for AI-assisted reasoning and navigation
• Experience with architectural, micro-architectural performance modeling
• Experience in hardware architecture and design issues
• Experience coding in C++ and Python and binding C++ to other languages
• Experience with computer architecture and software engineering principles
• Experience with data structures and algorithms
• Experience using software models to collect behavioral characteristics, and transforming that data into compelling performance analysis
• Note: Apple benefit, compensation and employee stock programs are subject to eligibility requirements and other terms of the applicable plan or program.
