iPhone Hardware Systems Engineer (SoC & System Performance)

Quick Facts

• Role: iPhone Hardware Systems Engineer (SoC & System Performance)
• Focus: iPhone SoCs and system performance (power, performance, and thermal behavior)

Description

In this role, you will measure, model, and tune the power, performance, and thermal behavior of future iPhone SoCs and systems. You will run hands-on performance and power measurements on real SoC silicon and iPhone systems, root-cause unexpected behavior, and translate findings into optimization opportunities. You will also build models and simulations to project future performance and influence architecture decisions.

Responsibilities

• Run hands-on performance and power measurements with hardware and software tools
• Analyze measurement data to identify root causes of unexpected behavior and generate optimization opportunities
• Analyze system behavior across CPU, GPU, Neural Engine, and the memory subsystem
• Evaluate power, performance, and thermal constraints to guide SoC/system architectural trade-offs
• Build models, analyses, and simulations to project performance for upcoming iPhone products
• Correlate models with measurements and validate assumptions
• Partner with silicon, hardware, and software teams; present findings and recommendations to technical and executive leadership

Requirements

• BS in Electrical Engineering, Computer Engineering, Computer Science, and 3+ years of industry experience
• Experience in computer, SoC, or system architecture for mobile devices
• Hands-on experience measuring performance using hardware and software tools
• Experience in performance modeling, analysis, and debug
• Strong Python programming skills; experience using AI tools to accelerate analysis and development
• Detail-driven mindset with rigor to validate data and models before drawing conclusions
• Genuine passion for system performance and building great products

Benefits

• Collaborate with a team focused on engineering details and sound architectural trade-offs
• Work directly on real iPhone systems and future silicon performance optimization
