Job description

About the Role

Senior Staff Test Engineer is a highly technical leadership role responsible for defining and driving system‑level validation strategies for server platforms across development and production environments. The role focuses on evaluating and integrating changes that impact manufacturing test systems, including firmware (BMC, BIOS, switch firmware), test infrastructure, and automation. It requires deep expertise in server architecture, networking, and power systems to assess risk, design validation methodologies, and ensure changes are safely deployed without impacting production stability.

Responsibilities

• Define and lead system‑level test architecture and validation strategy for server platforms across Design, NPI, and production environments (L10/L11).
• Own end‑to‑end validation of complex server systems, including CPU, GPU, memory, networking, storage, and power subsystems.
• Lead deep system‑level debugging and root‑cause analysis, isolating issues across hardware, BIOS/BMC, OS, networking stack, and power systems.
• Serve as the technical escalation point for complex system failures across development and production.
• Develop, deploy, and validate network configurations (VLANs, port configs, L2/L3 behavior) for server rack switches to support system bring‑up and testing.
• Debug system and rack‑level network issues, including connectivity, traffic flow, and protocol behavior between servers and switches.
• Lead validation of server power infrastructure, including power supplies, power shelves, and redundancy architectures.
• Design and develop custom test and repair solutions: digital tools (automation frameworks, validation utilities, debug software) and physical tools (debug cables, harnesses, fixtures, signal breakout solutions).
• Build and scale automated validation frameworks to improve test coverage, efficiency, and repeatability.
• Drive validation of server management interfaces, including BIOS/UEFI, BMC (OpenBMC), IPMI, and Redfish.
• Lead GPU system validation, including stress testing, workload validation, and system‑level interaction with CPU, memory, and networking.
• Mentor engineers and elevate team capabilities in system validation, networking, power systems, and test tool development.

Qualifications

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, Information Technology, or a related field.
• 8+ years of hands‑on experience in test engineering or system validation.
• Deep understanding of server architecture, including CPU, DIMMs, NICs, GPUs, FPGA, and system interconnects.
• Strong knowledge of BIOS/UEFI, BMC (OpenBMC), IPMI, and Redfish.
• Expertise with validation and stress tools such as FIO, Linpack, mprime/mprime95, and IPMITOOL.
• Proficiency in Python, Shell, or Perl for test tool development and validation.
• Familiarity with engineering change processes (ECO/ECA) and test impact analysis.
• Proven ability in system‑level debugging and root‑cause analysis across hardware, firmware, OS, networking, and power domains.
• Experience automating network setup and configuration using scripting (Python/Shell) and APIs.
• Strong debugging experience across system and network boundaries.
• Excellent communication skills, translating technical findings into clear recommendations for non‑technical stakeholders.

Preferred Skills

• Experience in high‑volume manufacturing environments (L10/L11).
• Experience validating GPU‑based or AI systems.
• Familiarity with data center environments and large‑scale deployments.
• Experience with liquid cooling systems.
• Strong background in failure analysis and reliability engineering.
• Contributions to test tools, frameworks, or validation standards.

Benefits & Compensation

• Typical base salary $116,250 to $155,000, with performance‑based annual bonus eligibility.
• 401(k) retirement savings plan with company match.
• Tuition reimbursement for eligible education programs.
• Comprehensive medical, dental, and vision coverage with leading providers.
• Mental health resources and employee wellness support programs.
• Paid time off (PTO) and company‑paid holidays.
• Parental leave and family care support programs.
• Structured training programs and on‑the‑job learning opportunities.
• Matching gifts and volunteer programs to support causes you care about.
