Software Performance Architect

Overview

We are the CPU Technology team, part of Arm Central Technology Group. This diverse engineering centric group invents, defines and architects Technologies to be deployed in tomorrow's IP solutions from Arm.

The CPU Technology team tackles next-generation Arm CPUs, inventing new concepts that will fuel billions of devices worldwide!

Responsibilities

• Analyse benchmarks and workloads to identify software and hardware optimization opportunities, analyse CPU performance and understand limitations we need to break through.
• Collaborate with various software teams, compiler, OS, applications to implement improvements.
• Collaborate with CPU design teams to identify bottlenecks.
• Write/Extract performance tests out of existing SW applications and run it on C/C++ models, emulators or real devices (Laptops, Smartphones, Servers…) on various operating systems.
• Work alongside with modelling engineers, CPU design teams and Arm Architecture group.
• Drive technical activities.
• Collaborate with Business teams and partners to present technical results.

Required Skills and Experience

• You graduated from a university or Engineering School, in Computer Science, Mathematics, Electronic / Electrical Engineering, or other related science
• You have bare minimum of several years of either software, hardware, or mathematic experience.
• You have some a proven experience in SW programming alongside with technical management
• You have a passion to innovate, think different, explore new avenues.
• You can work efficiently alone as well as in a team environment.

Nice To Have Skills and Experience

• Having strong SW development experience in one or severaldomains like HPC, machine learning, distributed applications, web technologies, mobile applications, databases, multi-media, …
• Having strong development skills in one or more high-level programming languages (C, C++, Java, Rust, …)
• Have SW performance analysis experience in platforms like Android (big/LITTLE systems), Windows, Linux and operating System settings impact (power management, frequency governor…) , single-threaded vs multi-threaded…
• Having working experience in CPU performance analysis, methodology (PMU-based, TDA, …), tools (linux perf, Intel Vtune, android simpleperf/perfetto, …), aarch64 assembly language programming
• Having knowledge on CPU architecture and micro-architecture performance techniques (branch prediction, prefetchers, …)
• You are used to develop and adapt some experimental application code to test new architectures.
• You demonstrate passion, drive and diligence.
• You have good written and verbal communication skills

In Return

You will develop the roadmap for Arm’s core interconnect and control subsystems, ensuring they are strategically aligned and technically validated across markets. While the initial focus is infrastructure, you will work across line of business and customers to ensure these foundational technologies are robust, driven, and reusable across Arm’s diverse product portfolio. Your ownership of requirement specs and roadmap rigor will ensure subsystem coherence across product generations — enabling Arm to scale from IP to complete system solutions.

Our 10x mindset guides how we engineer, collaborate, and grow. Understand what it means and how to reflect 10x in your work:

Accommodations at Arm

At Arm, we want our people to Do Great Things. If you need support or an accommodation to Be Your Brilliant Self during the recruitment process, please email To note, by sending us the requested information, you consent to its use by Arm to arrange for appropriate accommodations. All accommodation requests will be treated with confidentiality, and information concerning these requests will only be disclosed as necessary to provide the accommodation. Although this is not an exhaustive list, examples of support include breaks between interviews, having documents read aloud or office accessibility. Please email us about anything we can do to accommodate you during the recruitment process.

Arm is an equal opportunity employer, committed to providing an environment of mutual respect where equal opportunities are available to all applicants and colleagues. We are a diverse organization of dedicated and innovative individuals, and don’t discriminate on the basis of race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or status as a protected veteran.

Hybrid Working at Arm

Arm’s hybrid approach to working is centred around flexibility, where we split our time between the office and other locations to get our work done. Within that framework, we empower groups and teams to determine their own particular hybrid working pattern, depending on the work and the team’s needs. Details of what this means for each role will be shared upon application. In some cases, the flexibility we can offer is limited by local legal, regulatory, tax, or other considerations, and where this is the case, we will collaborate with you to find the best solution. Please talk to us to find out more about what this could look like for you.
