Principal Wireless Protocol Architect/Engineer

We are building a small team of versatile and enthusiastic leaders to create new products for the PlayStation community. Our team recently delivered the new PlayStation Link, PULSE Explore and PULSE Elite products, recently announced the FlexStrike 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.
