Principal Hardware Engineer - IO & Memory Systems

About the Role

SambaNova’s DataScale® platform pushes the limits of AI compute—and the integrity of every high-speed interface and memory subsystem is critical to its performance in the field. As a Principal Engineer, Post-Silicon Validation, you will own the bring-up, debug, and validation of high-speed IO and memory subsystems from first silicon through customer deployment.

This is a deeply technical, high-ownership role for an engineer who thrives on hard debug problems. You will operate across silicon, board, and software layers—leading cross-functional teams to root cause, driving issues to resolution, and building the infrastructure that makes future bring-up cycles faster and more reliable. If you have a bias for action, a sharp analytical mind, and the kind of depth that comes from years in post-silicon validation, this role was built for you.

What You’ll Do

System Bring-Up & Validation

Own post-silicon bring-up and validation of high-speed IO and memory subsystems, including characterization, functional validation, stress testing, and performance analysis.

Drive system power-on readiness—including debug infrastructure, tooling setup, and contingency planning—to enable first-pass bring-up success.

Debug & Cross-Functional Execution

Lead system-level debug across silicon, board, and software layers, driving complex issues to verified root cause and resolution.

Partner with design, firmware, verification, and systems teams to ensure timely bring-up and issue closure—without losing momentum.

Productization & Deployment

Support product validation, deployment, and RMA debug in partnership with systems and customer engineering teams.

Ensure product release readiness with a clear focus on stability, performance, and long-term field reliability.

Pre-Silicon & Design Feedback

Review SoC architecture, board design, and SI/PI analysis through the lens of post-silicon debug and real-world deployment.

Contribute to pre-silicon verification and emulation to improve bring-up efficiency and test coverage before first silicon arrives.

Infrastructure & Methodology

Develop scripts and tooling to automate validation, debug, and data analysis workflows—reducing manual effort and accelerating iteration.

Drive continuous improvement in post-silicon validation methodologies, debug infrastructure, and test scalability across product generations.

What You’ll Bring

Required

M.S. in Electrical Engineering or Computer Science.

7+ years of experience in post-silicon validation, system bring-up, or a closely related hardware engineering discipline.

Hands-on experience with high-speed IO or memory protocols: PCIe, Ethernet, HBM, CXL, UCIe, or similar.

Strong analytical skills applied to test development and data-driven debug.

Scripting proficiency in Python, Bash, or equivalent.

Demonstrated ability to lead cross-functional debugging efforts across hardware, firmware, and software teams.

High ownership, self-starter mindset—you drive issues to closure without waiting to be asked.

Clear and effective communicator with a proactive, collaborative approach to problem-solving.

Preferred

Deep expertise in high-speed SerDes training, adaptation, and equalization.

Experience with mixed-signal IO design and validation.

Hands-on proficiency with lab equipment including high-bandwidth oscilloscopes, BERTs, and VNAs.

Programming experience in C or C++ for tooling, automation, or low-level debug.
