The Post-Silicon Validation team bring up and validate the high-speed IO and memory subsystems inside SambaNova's DataScale platform, including PCIe, Ethernet, HBM, CXL, and UCIe interfaces. The team owns the path from first silicon power-on through field deployment: characterization, stress testing, performance validation, and root-causing issues that span silicon, board, and software. We work directly with design, firmware, verification, and system engineering to keep bring-up on schedule and sign off on validation before product releases.
About the roleSambaNova is seeking a Principal Engineer to own post-silicon bring-up, debug, and validation of high-speed IO and memory subsystems within the DataScale® platform. This role is central to delivering reliable, high-performance AI systems at scale.
You will lead system-level debug across silicon, board, and software layers, driving issues to root cause from first silicon through field deployment. This is a hands-on role for an engineer with deep expertise in high-speed interfaces and hardware debug, who can operate in ambiguity and execute with high ownership.
ResponsibilitiesSome of your responsibilities will include:
- Own post-silicon bring-up and validation of high-speed IO and memory subsystems, spanning characterization, functional validation, stress testing, and performance analysis
- Establish power-on readiness ahead of first silicon, including debug infrastructure, tooling, and contingency planning
- Lead system-level debug to root cause complex issues spanning silicon, board, and software layers
- Drive resolution with design, firmware, verification, and system teams to close issues and keep bring-up on schedule
- Partner with system and customer engineering teams on product validation, deployment, and RMA debug
- Own validation sign-off for product release against stability, performance, and field reliability targets
- Review SoC and board design and SI/PI analysis through a post-silicon debug and deployment lens
- Contribute to pre-silicon verification and emulation to improve bring-up efficiency and coverage
- Build scripts and tooling that automate validation, debug, and data analysis, and scale test coverage across systems
- Advance post-silicon validation methodology and debug infrastructure across programs
Required Qualifications- M.S. in Electrical Engineering, Computer Science, or a related field
- 7+ years of experience in post-silicon validation or system bring-up
- Experience with two or more high-speed IO or memory protocols such as PCIe, Ethernet, HBM, CXL, or UCIe
- Proven ability to lead cross-functional debug efforts to root cause and closure
- Strong analytical skills for test development and data analysis
- Proficiency in scripting such as Python and bash
- Clear and effective communicator with a proactive, collaborative approach to problem-solving
Preferred Qualifications- Deep understanding of high-speed SerDes training and adaptation
- Experience with mixed-signal IO design and validation
- Hands-on lab experience with oscilloscopes, protocol analyzers, and BERTs
- Experience with optical interconnect
- Ability to read and debug C/C++
