Senior Software Engineer

We design scalable, energy efficient-processors and related technologies to deliver the intelligence in applications ranging from sensors to servers, including smartphones, tablets, enterprise infrastructure and the Internet of Things.

Job Overview:

Arm is the industry's leading supplier of microprocessor technology, offering the widest range of microprocessor cores to address the performance, power and cost requirements for almost all application markets. Combining a dynamic ecosystem with over 1,000 partners delivering silicon, development tools and software, and with more than 90 billion processors shipped, our technology is at the heart of a computing and connectivity revolution that is transforming the way people live and businesses operate.

The Open-Source Software (OSS) team is responsible for developing and improving the software ecosystem around Arm's next generation of applications processors. This frequently means working with processors and other hardware technology not yet available to the public. We work on a range of development platforms, software-models, FPGAs and early silicon, sometimes many months before the processors are used in real products.

  • Have a strong background in microprocessor architectures and open-source software
  • Are a dynamic problem solver, capable of investigating and resolving sophisticated customer issues
  • Are passionate about new technology and want to help drive the global adoption of groundbreaking Arm IP
  • Able to demonstrate technical leadership and a curiosity about sharing knowledge with others

Then we want to hear from you!
