Budapest, Hungary

Job Overview:

As a Staff Software Engineer in Arm’s Userspace Enablement group, you will play a key technical leadership role in enabling next-generation Arm architecture features across major open-source platforms such as Linux and Android.

You will work closely with Arm architecture and silicon teams, as well as upstream open-source communities, to design, implement, and land high-impact changes that shape the future of Arm-based systems.

Responsibilities:

• Participate in the design and development of low-level software to enable new Arm architecture features across Linux, Android, and related userspace components.
• Collaborate closely with Arm architecture and silicon teams to translate architectural innovations into robust, upstream-ready software implementations.
• Architect, develop, and optimize core OS subsystems with a focus on performance, power efficiency, and security (e.g., memory management).
• Drive complex technical investigations across software layers, identifying root causes and leading resolution of performance, efficiency, and security issues.
• Lead code reviews, influence design decisions, and ensure high-quality contributions with upstream open-source communities.
• Mentor and technically guide junior and mid-level engineers, promoting best practices in low-level systems development.

Required Skills and Experience:

• Strong proficiency in C and C++, with deep understanding of OS internals such as memory management, scheduling, or virtualization.
• Solid expertise in 64-bit Arm architecture (Armv8-A) and the ability to apply new architectural concepts to real-world software.
• Strong understanding of modern compiler toolchains, particularly LLVM-based technologies.
• Proven experience leading technical discussions, code reviews, and upstream collaborations in open-source projects.
• Excellent problem-solving skills and a structured approach to debugging complex low-level software issues.

“Nice To Have” Skills and Experience:

• Familiarity with Android internals.
• Experience using or contributing to Rust in systems software.
• AArch64 assembly programming experience.
• Exposure to technical leadership, project coordination, or an interest in developing line-management skills.
