Job description

Job 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 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.
