Job Responsibility

We are developing LSI to be used in SIE products such as PlayStation, and you will be responsible for LSI specification formulation, verification and evaluation, and mass production support.

In specification, verification and evaluation, you will be required to understand hardware such as cache, memory, bus, etc. at a low level and to take a logical approach.

Understanding and experience in computer architecture is highly desirable. C/C++ and other programming skills are also required for LSI verification and evaluation.

Depending on your career and skill set, you will be expected to work in the areas of CPU/microcontroller, high-speed I/F, power management, and CPU peripherals.

LSI development work is carried out in close collaboration with many related parties, including product planning, hardware design, software development, and game developers.

This allows me to realize how the LSIs I develop will be used in PlayStation, and to strongly feel the value of my work.

Since this work requires cooperation with many people, it also requires good communication skills.

The CPU/GPU architecture used in PlayStation's LSI utilizes cutting-edge technology, and we are one of the few companies in Japan and around the world that have access to this technology.

We are also actively using cutting-edge semiconductor processes, which have become a hot topic in recent years, and you will have the opportunity to work at the very "cutting edge of the times".


Organization & Workplace introduction

We develop custom LSI that form the basis of SIE products such as PlayStation5 and PlayStation VR2.

From the product planning concept stage, we work closely with the product planning, HW design, and SW departments to formulate custom LSI requirement specifications.

In the prototype stage, we play an important role in confirming that the desired functions and performance can be obtained and incorporating them into the final product.

In collaboration with many world-class LSI design houses, we are developing highly competitive LSIs using cutting-edge architecture, IP (CPU, GPU, AI/ML, Codec, high-speed I/F, power control, security), and semiconductor processes.

By engaging in this work, you will be able to gain experience that is rare in Japan.

The team consists of experts in various fields such as LSI architecture, LSI design verification, HW design, and SW development.
