Senior Performance Engineer

We are looking for experienced SoC performance engineers who are passionate about pushing the boundaries of system performance on Arm IP. In this role, you will work alongside a talented and collaborative team of architects and performance engineers to shape the next generation of high-performance interconnect IP.
Your work will directly influence Arm systems used in infrastructure, automotive, and mobile markets, helping partners across the ecosystem build world-class products. This is a role for someone who enjoys deep technical challenges, takes pride in delivering high-quality work, and brings curiosity and ownership to everything they do.
What You'll Do

• Collaborate closely with micro-architects, RTL, and validation engineers to develop cycle-accurate timing and performance models for coherent and non-coherent interconnects.
• Drive new feature development, evaluating architectural trade-offs and their impact on system-level performance.
• Build high-quality, well-correlated performance models used for both internal analysis and customer evaluation.
• Partner with internal teams and external customers to deliver the collateral and insights needed to build the highest-performing systems on Arm technology.
• Design performance test suites, identify bottlenecks, validate expectations, and propose practical, data-driven solutions.

What We're Looking For
Required Skills and Experience

• Bachelor's degree (or higher) in Electrical Engineering, Computer Engineering, or Computer Science, with a strong foundation in computer architecture, microarchitecture, and performance analysis.
• 3+ years of experience in SoC performance modeling and/or RTL within the semiconductor industry.
• A proven track record of developing cycle-accurate performance models and evaluating microarchitectural features for future performance improvements.
• Strong C++ skills for large-scale software development.
• Experience with SystemC TLM and proficiency in Python scripting.

Nice to Have

• Knowledge of interconnect microarchitecture, PCIe, and CHI protocols.
• Familiarity with realistic workloads used for system performance optimization.
• Experience with performance verification methodologies and correlating software models with RTL.

What Sets You Apart
Beyond technical expertise, we're looking for someone who:

• Brings a can-do, proactive attitude and takes ownership of problems end-to-end.
• Is willing to go the extra mile to deliver robust, high-quality solutions.
• Has a strong sense of curiosity and is eager to learn new domains, even when they're outside your current comfort zone.
• Thrives in a collaborative environment and enjoys learning from-and contributing to-a team of experts.
