• Lead complex root-cause analysis across hardware, firmware, operating systems, networking, storage, power, and thermal domains.
• Drive platform manufacturability, factory readiness, production validation, and deployment standards.
• Develop validation, characterization, diagnostics, and automation tools using Python, Bash, and/or C.
• Support qualification and lifecycle management of power supplies, PDUs, breakers, cabling, cooling systems, and infrastructure components.
• Define and validate firmware configurations, deployment settings, and manufacturing handoff requirements.
• Collaborate with vendors, manufacturing partners, and field teams to resolve integration and deployment issues.
• Support regulatory, EMC, and safety compliance activities for enterprise data center deployments.
• Contribute to high-density AI/GPU infrastructure initiatives, including advanced air- and liquid-cooled systems.

Required Qualifications

• Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field, or equivalent practical experience.
• 8+ years of experience in systems engineering, platform engineering, infrastructure engineering, or a related technical field.
• Strong systems engineering experience across server, storage, networking, or infrastructure platforms.
• Experience with data center power systems, redundancy models, and thermal design considerations.
• Strong Linux and command-line experience.
• Experience with system debugging and performance analysis tools such as fio, iostat, perf, sar, iperf, or `sysbench.
• Proficiency in Python, Bash, C, or similar scripting/programming technologies.
• Experience with firmware, BIOS, BMC/iDRAC, or large-scale system configuration.
• Familiarity with high-speed networking technologies such as Ethernet or InfiniBand.
• Experience with enterprise storage technologies including NVMe, RAID, distributed storage, replication, or erasure coding.
• Understanding of rack-level infrastructure, including PDUs, cabling, grounding, and power distribution.
• Experience supporting manufacturing, system integration, or factory deployment activities.
• Ability to work across multiple technical disciplines and take ownership of complex system-level challenges.
• Strong technical leadership, communication, troubleshooting, and cross-functional collaboration skills.

Preferred Qualifications

• Experience with three-phase data center power distribution, grounding methodologies, breaker coordination, and N/N+1/2N redundancy models.
• Experience with AI, GPU, or high-density compute infrastructure.
• Experience with thermal characterization, cooling validation, or liquid cooling technologies.
• Familiarity with data center facility interfaces and regional power standards.
• Experience working with global ODM/OEM vendors and manufacturing partners.
• Experience with enterprise hardware regulatory, EMC, and safety requirements.

What You'll Bring

• Strong systems-thinking and technical leadership skills.
• Ability to influence cross-functional teams without direct authority.
• Strong ownership and problem-solving mindset.
• Ability to lead high-severity troubleshooting and root-cause analysis.
• Comfort working in fast-paced, technically complex environments.
• Curiosity and willingness to learn emerging infrastructure and AI technologies.
