Job ID 2025-14673 Date posted Jun. 16, 2026 Location Cambridge, United Kingdom Category Software Engineering

The Central Technology Team within Arm develops key technologies which will form the foundation of future products.

You will join a multinational, multifaceted, collaborative and highly motivated Machine Learning Hardware Architecture team in Central Technology to help craft the direction of Machine Learning in Arm IP designs.

Job Overview:

You will be working on a team that enables the capabilities of Arm's machine learning accelerators by creating tools that push the limits of the architecture. These tools are used across the architecture group to demonstrate that proposed features are suitable for implementation and can be unlocked by the software teams.

Responsibilities:

Develop tools that expose proposed hardware features and evaluate the resulting performance.
Work with hardware architects to define the software interfaces to new features.

Required Skills and Experience :

Strong programming experience in C++ and Python.
Solid understanding of computer architecture.
Good written and verbal communication skills.
Experience developing software interfaces on large projects.
Ability to understand accelerator designs.

“Nice To Have” Skills and Experience :

Familiarity with Machine Learning frameworks.
Experience working with architects and modellers to test proposed features.
Understanding of memory systems and hierarchy.

In Return:

You will join an established and experienced team working with innovative technologies in an agile environment which requires proactivity, multifaceted approaches to problem solving and creative thinking.

Please note that a relocation package (including visa sponsorship support) is available for this role, for candidates who require it.
