AI Hardware System Architect

SambaNova is a leader in next-generation AI infrastructure, delivering a full-stack inference platform for customers worldwide. At the core of SambaNova's technology is the RDU (Reconfigurable Dataflow Unit) — a chip built on a dataflow architecture rather than the traditional GPU model. Its decode performance is especially strong for agentic workloads like multi-turn agents, code generation, and long-running applications. RDUs are packaged into SambaRack, rack-scale hardware that lets customers deploy state-of-the-art models with better performance, greater energy efficiency, and faster time to value.

About the team

The System Architecture team owns architecture for RDU-based platforms at the board, rack, and cluster level, covering SambaRack-class server and rack design, the scale-up and scale-out interconnect fabric, power delivery, and air and liquid cooling. We write the specifications ODM/OEM and component partners build to, evaluate their proposals, and make the build, buy, and co-develop calls. We define the bring-up, validation, and qualification plan for each platform, and work with signal and power integrity engineers, SambaFlow, ML performance, and datacenter operations to keep architecture decisions matched to the workloads running on the systems.

About the role

SambaNova's Reconfigurable Dataflow Unit (RDU) powers a full-stack, chip-to-model AI platform used by enterprise and government customers, delivered both on-premises and in the cloud. As a Senior RDU System Architect, you'll be a part of the team that turns silicon into shippable systems — SambaRack-class server and rack designs, the scale-up/scale-out fabric that links RDUs together, and the power and cooling envelope that lets dense AI compute run efficiently in a real data hall. You'll set direction across build, buy, and co-design decisions with our hardware partners, write the specifications those partners build to, and stay engaged from architecture definition through bring-up, qualification, and fleet deployment.

Responsibilities

Platform & Rack Architecture

Being a part of the team defining the architecture of RDU-based server and rack platforms, from board layout and chassis design through full-rack integration, translating product and customer requirements into system specifications that engineering teams and vendors can build to.

Select and validate major system components — RDU sockets, memory modules, power supplies, chassis mechanicals — balancing performance, power envelope, and manufacturability.

Build performance and cost models to compare candidate rack configurations before committing to a design.

Fabric, Power & Thermal

Architect the scale-up and scale-out interconnect fabric that links RDUs into larger training and inference clusters, choosing topology, switch/NIC hardware, and optics to hit bandwidth and latency targets.

Own the power delivery architecture (including high-density/48V-class distribution) and the cooling strategy — air and liquid — needed to keep dense, multi-socket racks within thermal budget.

Work with signal and power integrity engineers to confirm interconnect and power designs hold up once they leave simulation and reach the lab.

Partner & Supply Chain Engineering

Evaluate ODM/OEM and component vendor proposals against SambaNova's system requirements, and decide where to build in-house, buy off the shelf, or co-develop with a partner.

Flag schedule or technical risk in partner designs early, and drive the changes needed to close the gap.

Maintain a working map of the vendor and technology landscape — boards, interconnect, power, cooling — that feeds SambaNova's platform roadmap.

Bring-Up, Qualification & Field Reliability

Define the bring-up, validation, and qualification plan for each new platform, including the reliability (RAS) and telemetry targets it needs to hit once it's running in a customer's data hall.
