Senior Software Engineer - Models (C++)

Our software group is responsible for supporting and bringing out the best in the hardware we design as well as working with our hardware engineers to make things even better. Software drives our hardware that is shipped around the world and used in a plethora of industries. Our people are passionate and care about producing the best software possible to power the world.

Job Overview:

We are looking to welcome a Senior Software Engineer into our growing team, based in Cambridge.

Our team develops simulations of Arm’s next-generation technologies—known as Fast Models—that enable the developer ecosystem to write software years before actual hardware exists. These high-performance models are essential for enabling software development across embedded devices, client computing, and high-performance systems.

Arm is looking for a highly skilled and motivated engineer to contribute to the modelling of innovative technologies that will power future computing systems.

We use modern, industry-standard tools and techniques, value the art of great code reviews, are passionate about testing through automated continuous integration, and take pride in collaborating to achieve our best work.

Responsibilities:

Work on varied projects at all stages of the software development lifecycle, from design through to implementation and testing.

Develop highly efficient C++ models of the Mali product lines, including GPUs, NPUs, ISPs, and more.

Collaborate closely with other Arm teams to ensure model accuracy and integration into software workflows.

Improve model performance, scalability, and usability, helping optimize virtual prototyping solutions.

Contribute to code reviews, testing strategies, and continuous integration to maintain high-quality standards.

Required Skills and Experience :

Strong hands-on experience with Modern C++ (C++11/14/17/20).

Knowledge of software methodologies, tools, and processes, including code review best practices.

Experience with automated test frameworks to maintain functionality and performance.

A creative and structured approach to problem-solving.

A curious and inquisitive mindset, with a passion for continuous learning and self-improvement.

“Nice To Have” Skills and Experience :

Understanding of hardware and software architectures of a System-on-Chip (SoC).

Experience with GPU architecture and modeling.

Familiarity with virtual prototyping tools such as Fast Models, QEMU, Simics, or Gem5.

In Return:

This role offers a unique opportunity to work at the cutting edge of Arm technology, contributing to the development of next-generation software models that enable software development long before silicon exists.

If you’re passionate about software modeling, performance optimization, and SoC architecture, we’d love to hear from you!
