Principal Solution Engineer

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.

Responsibilities:

• 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.

Required Skills and Experience:

• 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.

"Nice To Have" Skills and Experience:

• 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.
