• Lead technical engagements with hyperscalers, ODMs, OEMs, and AI system partners.
• Support customer architecture discussions, system design-in, evaluation, bring-up, and deployment.
• Lead on-site and remote debugging, performance tuning, and system integration.
• Translate customer requirements into actionable feedback for product, silicon, firmware, and engineering teams.

• Influence post-silicon validation strategies for next-generation switching platforms.
• Execute system-level integration and troubleshoot complex hardware and software issues.
• Debug challenges involving PCIe Gen 6/7, UALink, UCIe, signal integrity, firmware, and software stacks.
• Partner with hardware, firmware, and SI/PI teams to identify root causes and deliver production-ready solutions.

• Serve as the primary Scorpio applications expert across sales, marketing, product, and engineering functions.
• Mentor junior applications engineers and provide technical guidance across customer projects.
• Represent the organization at customer executive reviews, industry forums, and relevant standards bodies.
• Develop technical collateral, white papers, training materials, and customer-facing documentation.
• Contribute customer and technical insights that help shape product and technology roadmaps.

• Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related technical field.
• 8+ years of experience in product applications, systems engineering, or post-silicon validation involving high-speed connectivity or networking silicon.
• Strong understanding of physical-layer technologies and high-speed serial interfaces such as PCIe, Ethernet, UALink, or UCIe.
• Hands-on experience with laboratory bring-up, system debugging, and integration using oscilloscopes, BERTs, protocol analyzers, or similar equipment.
• Proven experience working directly with hyperscalers, cloud providers, Tier-1 OEMs, or ODMs.
• Excellent communication and presentation skills with the ability to translate complex technical concepts into clear customer-facing solutions.

• MS or PhD in Electrical Engineering, Computer Engineering, or a related discipline.
• Experience with PCIe Gen 6/7, UALink, or UCIe and related compliance testing.
• Knowledge of AI/ML rack-scale architectures, GPU fabrics, and accelerator interconnects.
• Python or shell scripting experience for validation, automation, and diagnostics.
• Experience contributing to industry standards organizations such as PCI-SIG, UALink Consortium, or UCIe.
• Technical publication, white-paper, or industry presentation experience.
