Job description

The roleWe are seeking an IT Infrastructure Engineer – RMA & Hardware Diagnostics to own advanced hardware troubleshooting and RMA lifecycle management within our production data center environments. This role serves as the escalation point for complex server and firmware-related issues that impact system reliability and fleet availability.You will be responsible for deep diagnostics across enterprise server platforms, performing structured root cause analysis, validating failed components, and managing end-to-end warranty replacement processes with OEM vendors. This is a hands-on technical role with direct impact on hardware reliability, SLA performance, and operational scalability.You will work on-site in one of our data centers, collaborating closely with L1/L2 technicians, infrastructure engineers, and vendors to reduce repeat failures and improve overall hardware quality across the fleet.You’re welcome to work in our Minnesota location.

Responsibilities will include:

• Perform advanced firmware and hardware diagnostics on enterprise server platforms, including CPU, memory, PCIe devices, GPUs, storage subsystems, and power components
• Troubleshoot complex hardware failures using system logs, BMC/IPMI interfaces, BIOS diagnostics, and vendor-specific tooling
• Act as the primary escalation point for L1 and L2 technicians on high-impact hardware incidents
• Conduct structured root cause analysis and document findings to prevent repeat failures
• Own the full RMA lifecycle, including validation of failed components, warranty claim creation, vendor coordination, tracking, and resolution
• Interface directly with OEM vendors to elevate recurring hardware defects and drive corrective action
• Analyze hardware failure trends and report metrics such as repeat RMA rates and component reliability
• Develop and standardize diagnostic playbooks, troubleshooting workflows, and hardware validation procedures
• Validate replacement components prior to redeployment into production environments
• Collaborate cross-functionally with data center operations, procurement, and engineering teams to improve hardware lifecycle processes
• Contribute to reducing MTTR and improving fleet-wide reliability through process improvements and knowledge sharing

We expect you to have:

• 5+ years of hands‑on experience working with enterprise server hardware in a production data center environment
• Deep understanding of x86 server architecture, including CPUs, memory, PCIe devices, storage controllers, GPUs, and power subsystems
• Strong experience performing firmware and BIOS/BMC diagnostics and upgrades
• Advanced Linux command-line troubleshooting skills, including log analysis and hardware‑level diagnostics
• Experience working with remote management interfaces such as IPMI, iDRAC, iLO, or equivalent
• Proven experience managing hardware RMA processes and working directly with OEM vendors
• Ability to conduct structured root cause analysis and document technical findings clearly
• Familiarity with hardware monitoring systems and failure trend analysis
• Strong ownership mindset and ability to operate independently in mission‑critical environments
• High proficiency in spoken and written English

It will be an added bonus if you have:

• Experience performing board‑level diagnostics and component‑level repair (SMD rework)
• Familiarity with data center networking equipment and basic network troubleshooting
• Experience supporting GPU‑dense or high‑performance compute environments
• Valid driver’s license
