CPU Technology Intern
ArmJob Title
CPU Technology Intern
Role Summary
Six-month internship within Arm's CPU Technology team based in Sophia Antipolis, focusing on CPU microarchitecture, performance analysis, and tooling to characterize Arm-based systems.
Interns will join experienced CPU and performance architects and work on one of two projects: Device Analysis (performance tooling and automated data workflows) or CPU Microarchitecture (system-to-CPU information modelling and evaluation).
Experience Level
Entry-level internship (suitable for students and early-career candidates). The role is a fixed-term internship with a 6-month duration starting in 2027.
Responsibilities
Contribute to research, tooling, and experiments that improve understanding of CPU behaviour and performance.
- Develop and extend tooling and methodologies for CPU performance analysis on real devices (Device Analysis).
- Automate performance experiments, data collection, processing, and analysis across devices and workloads.
- Investigate system-to-CPU information, evaluate useful information granularity/timescales, and assess value via modelling and simulation (CPU Microarchitecture).
- Use tools to run experiments on real hardware and interpret results to provide microarchitecture and workload insights.
- Collaborate with CPU and performance architects; document findings and reusable workflows.
Requirements
Minimum practical skills and eligibility required for successful internship performance.
- Solid programming experience in low-level languages such as C, C++ or Python and familiarity with Linux development environments.
- Good understanding of computer architecture fundamentals and interest in CPU performance analysis.
- Ability to work in a team, strong curiosity, and willingness to learn.
- Must have the right to work in France for the full duration of the internship; Arm cannot provide visa sponsorship for this role.
- Ability to provide university contact details and participate in the required French internship agreement (Convention de Stage).
Nice-to-have:
- Familiarity with CPU microarchitecture concepts and hardware performance monitoring (PMU).
- Experience with Linux performance analysis tools and methodologies.
- Experience with scripting, automation, or data analysis workflows.
Education Requirements
Currently enrolled in a Bachelor's, Master's or PhD program in Computer Engineering, Electrical Engineering, Computer Science, or a related technical field; alternative degrees considered if supported by relevant experience. French internships require a Convention de Stage (tripartite internship agreement). Equivalent practical experience may be considered where applicable.
