Principal Solution Engineer

Are you passionate about bringing innovative architecture to life in the real world? Do you thrive at the intersection of low‑level software and strategic collaboration? We're looking for a Principal Solution Engineer who brings technical excellence, and passion to make it happen!

In this high‑impact role, you’ll lead the enablement of Arm’s most advanced architectural features across compilers, operating systems, tools, and first‑party applications. Your work will ensure that our customers extract maximum performance and value from Arm‑based platforms, and you’ll do so by guiding both internal engineering efforts and strategic customer relationships.

This is more than a technical leadership role—it's your opportunity to shape product direction, build enduring partnerships, and drive real‑world software transformation! You'll join a team that grows with solving hard problems, working across boundaries, and pushing industry standards forward.

• Drive end‑to‑end enablement of innovative Arm architecture features across the compiler, OS, and broader software stack—turning hardware innovation into performance uplift.
• Translate microarchitectural insights into real software strategies, in close collaboration with hardware and architecture teams.
• Develop and optimize backend compiler components, including instruction selection, vectorization, and code generation.
• Analyze and tune performance across diverse workloads, benchmarks, and platforms.
• Lead the design and implementation of both general‑purpose and target‑specific compiler optimizations.
• Act as a strategic technical partner to customers, identifying high‑value engineering opportunities that align business and technical goals.
• Represent the compiler and architecture team in technical customer engagements, providing deep architectural and compiler insight.
• Influence internal roadmaps based on customer feedback and real‑world integration challenges.
• Support the growth of new team members by sharing knowledge, offering mentorship, and fostering an environment of technical curiosity, collaboration, and high‑quality delivery.
• Work effectively on confidential and closed‑source projects, balancing innovation with trust.

• Deep, hands‑on experience in compiler development, particularly in backend engineering, performance tuning, and code generation.
• Strong understanding of microarchitectural‑level performance, and a consistent track record of optimizing software to match.
• Proficiency in C/C++ and groundbreaking software engineering practices.
• Excellent debugging, analytical, and problem‑solving skills in complex compiler environments.
• Experience with LLVM, GCC, or proprietary compiler stacks.

• Strong knowledge of Arm architecture, including scalar, SIMD, and vector extensions.
• Demonstrated success in technical customer engagement, including shared design or solution delivery.
• Experience in shaping strategic technical relationships or co‑engineering efforts with key partners.
• Comfortable navigating proprietary or closed‑source ecosystems with discretion and responsibility.
