Staff Power Performance Engineer

Power & Performance Engineer – SoC / CPU / GPU / AI (Staff level)

Full-Time Permanent Contract

Total Comp: Equity, Annual Bonus, Standard Benefits, Healthcare Plan

A leading semiconductor company designing high-performance chipset platforms used across a broad range of consumer and industrial products. Their systems and architecture teams own the power, performance and thermal behaviour of chipsets spanning CPU, GPU, AI/NPU, modem and multimedia subsystems.

They are looking to add experienced Power & Performance Engineers across teams covering GPU/AI power modelling, thermal and peak-current limits management, and cross-chipset performance benchmarking.

Key Responsibilities:

• Developing and maintaining power models for GPU, CPU, AI/NPU and other SoC subsystems, correlating estimates against silicon and workload data
• Analysing GPU/CPU architecture and microarchitecture to identify power bottlenecks and propose HW, SW or algorithmic optimisations
• Characterising AI/ML workload behaviour and correlating it with power consumption across GPU generations
• Defining and managing thermal performance and peak-current limits, working across power, architecture and design teams to meet reliability standards
• Benchmarking and competitively analysing power/performance across CPU, modem, application processor, multimedia and interconnect against industry devices
• Contributing to architectural trade-off studies that influence chipset and product roadmap decisions
• Collaborating cross-functionally with hardware, software, ML and silicon validation teams

Ideal Profile:

• Strong background in SoC power, performance or thermal engineering (CPU, GPU, AI/NPU or modem)
• Experience with power modelling, DVFS, low-power architecture or performance benchmarking methodologies
• Comfortable working with pre-silicon and post-silicon data, correlating estimates against real measurements
• Familiarity with industry-standard benchmarks and workload characterisation tools
• Staff-level+ experience preferred; open to Senior engineers with clear ownership of power/performance work
• Strong communication skills, able to present technical trade-offs to cross-functional and leadership audiences

This is a strong opportunity to join a market-leading chip architecture organisation, working at the intersection of power, performance and silicon engineering on products shipping at global scale.
