Role Overview 

As a Principal Engineer on the Scorpio Product Applications team, you will help customers and internal teams deploy high-performance PCIe fabric solutions for rack-scale AI infrastructure. You will translate complex system requirements into practical architectures, lead platform bring-up, and guide the integration of Scorpio switches across demanding CPU, GPU, NIC, storage, and accelerator designs. 

This role connects product strategy, firmware, and real-world system behavior. You will work across hardware, firmware, validation, and customer-facing teams to solve interoperability challenges, accelerate adoption, and shape the next generation of PCIe Gen 6/Gen 7 connectivity. Your work will directly influence how AI systems scale using purpose-built fabrics, UALink, and UCIe. 

Key Responsibilities 

• Product Applications and Customer Enablement  

• Lead technical engagements with customers and ecosystem partners to define Scorpio-based PCIe Firmware architectures and deployment requirements. 

• Develop reference designs, application guidance, technical presentations, and system-level collateral that accelerate customer adoption. 

• Translate customer use cases into clear Scorpio Firmware requirements, integration plans, and prioritized technical actions. 

• PCIe and Firmware Bring-Up  

• Drive system bring-up, debug, and interoperability across PCIe hosts, BMCs, GPUs, NICs, storage devices, and other high-performance endpoints. 

• Partner with firmware teams to define, implement, and validate device configuration, traffic routing, boot flows, telemetry, recovery mechanisms, and field-debug capabilities. 

• Analyze link training, enumeration, performance, error handling, data traffic and system stability issues using protocol traces, logs, and lab instrumentation.
