Performance Architect- Platform Architecture in London

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.

Every generation of Apple silicon raises the bar for what a GPU and SOC can do: more performance, more efficiency, in tighter power envelopes than the industry thought possible. As a Performance Engineer on this team, you'll help decide where that bar goes next.

You’ll join a group shaping the architecture of Apple's GPU and SOC from the ground up, researching the ideas that turn into the next leap forward. The work is deeply collaborative: you'll partner with teams across software and hardware engineering to pressure-test ideas, refine the promising ones, and plant the seeds for new ones. You'll dig into the workloads that matter, across both today's products and tomorrow's categories, to find the bottlenecks worth solving and the opportunities worth chasing.

In This Role, You Will:

• Research and propose novel ideas that help shape Apple's platform direction
• Prototype architectural and micro-architectural concepts in our existing C++ performance models
• Gather, analyze, and validate measured and simulated results to identify bottlenecks and evaluate new ideas
• Present findings and recommendations to peers and leadership
• Collaborate with multi-functional teams to turn ideas into shipped architecture

Minimum Qualifications:

• Deep expertise in computer architecture and micro-architecture — CPU, GPU, SOC, or adjacent domains
• Hands-on experience with performance and/or power simulation environments
• Skilled at analyzing and characterizing complex workloads

Preferred Qualifications:

• Familiar with common data structures, algorithms, and design patterns
• Working knowledge of C++ and Python
• 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.

At Apple, we believe accessibility is a fundamental human right. You’ll find that idea reflected in everything here — in our culture, our benefits and our digital tools. By welcoming as many perspectives as possible, we help you build a career where you feel like you belong.
