Principal Wireless Protocol Architect​/Engineer

Why Sony Interactive Entertainment?

Sony Interactive Entertainment isn’t just the Best Place to Play — it’s also the Best Place to Work. Sony Interactive Entertainment (SIE) is the company behind the Play Station brand. As a subsidiary of Sony Group Corporation, we’re part of a proud legacy of innovation and excellence. SIE is a dynamic technology company, delivering cutting‑edge hardware and network services to more than 100 million people and an entertainment leader, home to some of the most beloved and recognizable intellectual properties (IP) in the world.

Our role at SIE is to create and nurture the experiences under the Play Station brand, a name synonymous with entertainment excellence and creativity.

We are building a small team of versatile and enthusiastic leaders to create new products for the Play Station community. Our team recently delivered the new Play Station Link, PULSE Explore and PULSE Elite products, recently announced the Flex Strike and PULSE Elevate products, and are hard at work on what comes next. We need an experienced and innovative firmware engineer to help build and support our new products and features.

In this role, you will be the technical point of accountability for wireless across accessories: hardware, platform software, audio, security, and product all will route protocol questions to you. You will represent the protocol and the implementation to silicon and ODM partners, evaluate combo-SoC roadmaps, drive vendor firmware defects to resolution, and design so that a supplier change is a port, not a rewrite.

You will write the technical strategy documents that let a Director and a VP make an informed decision. And, grow the technical depth by being the leader that mentors senior engineers toward staff and principal, and raise the design-review bar for the whole org.
