Job description

Summary The hardest problems are the ones worth solving. We believe that meaningful progress comes from pushing past where it's easy to stop, and that a team with the right people and relentless drive can outperform even its own ambitions. We're looking for highly motivated, innovative engineers to join the GPU Performance Modelling Team, the group driving advanced exploration of Apple's next-generation GPU architectures and micro-architectures. It's a highly visible role at the heart of the chip design effort, working across every discipline involved, with a direct hand in getting high-performance products into the hands of millions of customers. This isn't easy work, but if you've been looking for a place where ambition and craft genuinely matter, you've found it.

Description Every architectural idea worth shipping has to be proven in simulation first - and the quality of those simulations is only as good as the model behind them. This role is where rigorous software engineering meets cutting-edge silicon research: you'll build and evolve the C++ performance models that the entire GPU and SOC architecture team relies on to explore what comes next. You'll own the creation and maintenance of high-performance C++ models for our next-generation architectures, writing and debugging the simulator that turns architectural ideas into something we can actually measure. Beyond the day-to-day of the model itself, you'll architect new simulator features and find clever ways to push simulation performance further. You'll work shoulder-to-shoulder with world-class GPU and SOC architects, helping translate their ideas into working simulations used for research, performance analysis, and micro-architecture tuning. Along the way, you'll help shape those ideas yourself, and as part of the broader architecture and performance team, you'll also help keep the simulation environment healthy and look for ways to make everyone around you more productive.

In This Role, You Will

• Build C++ performance models of proposed architectural solutions and features
• Strengthen Apple's modelling platform by developing tools and reusable components used across the company
• Gather, analyze, and validate measured and simulated results to compare architectural design alternatives
• Collaborate with multi-functional teams to develop architectural solutions

If you love writing software that other engineers depend on, and want that software to shape the silicon inside Apple's next generation of products, we'd love to talk.

Minimum Qualifications

• Solid understanding of data structures, algorithms, and design patterns
• Strong software engineering skills in modern C++
• Familiar with Python or another scripting language
• General knowledge of computer architecture

Preferred Qualifications

• Experience working with cutting-edge graphics applications, games, or benchmarks
• Comfortable working in uncertain environments and through ambiguity
• Strong communicator who can influence decisions and negotiate trade-offs

At Apple, we're not all the same. And that's our greatest strength. We draw on the differences in who we are, what we've experienced and how we think. Because to create products that serve everyone, we believe in including everyone. Therefore, we are committed to treating all applicants fairly and equally. As a registered Disability Confident employer, we will work with applicants to make any reasonable accommodations. Apple will consider for employment all qualified applicants with criminal backgrounds in a manner consistent with applicable law. Learn more
