About the Team

The company’s Data Center team is at the forefront of innovation, developing cutting-edge technologies that power the world’s most advanced data centers.

Our team brings together system architects, advanced packaging technology developers, and SoC design experts dedicated to creating high-performance, power-efficient, scalable, and reliable solutions for data center applications.

We collaborate closely across technical disciplines to push the boundaries of compute technology and shape the future of cloud computing, hyperscale infrastructure, and AI data centers.

Role Summary

The company is seeking a highly specialized Datacenter Compute Accelerator Architect to lead the architecture, design, and integration of dedicated hardware accelerators within our next-generation data center silicon.

As data center workloads increasingly rely on heterogeneous computing, offloading critical functions—including cryptography, data compression, networking, memory movement, and AI processing—from the main CPU or compute cores is essential to maximizing system-level performance and efficiency.

In this role, you will define the architecture of on-chip uncore accelerators and ensure their seamless integration with coherent interconnects, memory hierarchies, virtualization infrastructure, and the hypervisor software stack.

You will work at the intersection of hardware and software to deliver scalable, high-throughput, low-latency acceleration solutions for hyperscale cloud environments.
