# Performance Modelling Architect - Platform Architecture

- **Company:** Apple Inc.
- **Location:** London, UK
- **Contract:** Permanent contract
- **Skills:** Computing Platforms, C++ (Programming Language), Microarchitecture, Data Structures, Software Debugging, Software Design Patterns, Python (Programming Language), Software Engineering, Scripting, C++14
- **Published:** August 22, 2026
- **Apply:** https://www.totaljobs.com/job/performance-architect/apple-job107886206

## About the Role

* 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, * 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

## 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 solutionsIf 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.
