Senior Engineer – FuSa Toolchain Overview

The Software Engineering group focused on CE-SW develops and enhances the software ecosystem that supports Arm’s next-generation architectures and systems.

• Enhance the automated testing frameworks that support toolchain quality and reliability.
• Write and maintain documentation required for safety-related work.
• Contribute to compiler technology work in a team that engages with the broader LLVM ecosystem.

Skills and experience needed

• Very strong C/C++ programming skills, with the ability to introduce major new functionality and investigate and resolve complex technical issues.
• Some knowledge of assembly language, along with strong debugging capability, is preferred.
• Experience across both application software and low-level systems, plus a solid understanding of system architecture, ideally Arm architecture, and operating system basics.
• Comfort using standard software engineering practices, tools, and workflows, including code review.
• Strong communication and collaboration skills, with excellent written and spoken English.

Additional experience that would be an advantage

• Background in compiler development, particularly work involving LLVM.
• Low-level programming experience in Arm assembly.
• Practical use of git for source control.
• Test development using continuous integration systems such as Jenkins.
• A degree or equivalent professional experience demonstrating the same level of capability.
