Principal GPU Architect - Performance / Power Modelling / SystemC / C++ / Python
Our client is a global fabless semiconductor company enabling nearly 2 billion connected devices a year. They are a market leader in developing innovative systems on chip (SoC) for mobile devices, home entertainment, connectivity and IoT products. As a leader in SoC design, the company's GPU IP team is focused on industry leading, feature rich and PPA competitive GFX IP optimisation, customisation and development, deployed across flagship and mainstream mobile SoC as well as adjacent markets including laptop, IoT, AI, VR/AR and automotive.
The team is growing across Architecture, Driver, Compiler, Performance, Power and Model disciplines at their Cambridge site.
Please note - this role is 100% onsite in the Cambridge area
What you will be doing
- Define and develop best in class GPU architecture and performance and power models for next generation SoCs, building and maintaining cycle accurate, performance and functional models of GPU subsystems such as shader cores, fixed function units, memory hierarchy and interconnect.
- Using modelling and profiling, explore architectural tradeoffs across performance, power and area to guide micro-architecture decisions, and analyse workloads including games, graphics benchmarks, GPU compute and AI/ML kernels through simulation and hardware profiling to identify bottlenecks and optimisation opportunities.
- Collaborate closely with model, RTL, DV, driver, compiler and performance teams to ensure architectural intent is correctly implemented, verified and tuned, and provide architectural input to compiler, driver and runtime teams to maximise utilisation of the GPU hardware.
- Develop methodologies, tools and automation flows for GPU performance estimation, capacity planning and regression analysis.
- Lead debug and root cause analysis of performance, power and bandwidth issues seen in models, emulation and silicon.
- Drive cross team technical discussions that influence the roadmap for next generation GPUs.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What we're looking for
- Bachelor's, master's or higher degree in computer science, electrical or computer engineering or a closely related field.
- Experience in GPU, graphics, high performance compute, AI accelerator or related architecture and modelling areas.
- Strong experience with performance and/or cycle accurate modelling, simulation frameworks or architectural exploration for complex SoCs or accelerators, a solid understanding of graphics and compute APIs such as Vulkan, OpenGL and DirectX and/or GPU compute frameworks including OpenCL, CUDA or Metal, and proficiency in at least one modelling or implementation language such as C/C++, SystemC or Python.
- Scripting for data analysis and automation.
- Experience with performance analysis tools, profiling methodologies and workload characterisation for games, benchmarks and GPU compute workloads is important, as are strong written and verbal communication skills and the ability to present complex technical topics clearly and drive consensus across teams.
