Hardware Diagnostics Engineer - Infrastructure

About TensorWave

Our mission is simple: deliver seamless, secure, reliable, and resilient AI compute at scale. We've built a versatile cloud platform that eliminates infrastructure barriers, empowering builders to focus on innovation instead of fighting their stack. Because breakthrough AI should move at the speed of ideas, not infrastructure.

About the Role

We are looking for a Hardware Diagnostics Engineer to run burn-in, triage what fails, work servers out-of-band, and own RMAs end to end. If you like hardware that misbehaves in ways that take real work to explain, this is a good seat.

Before any GPU server carries a customer workload, it has to prove it works — under load, at temperature, for hours. When it doesn't, somebody has to figure out why, get replacement hardware in, and send the failed part back to the vendor.

What You’ll Do

Run server and GPU burn-in and stress testing, interpret the results, and decide whether hardware is production-ready

Triage failures across GPUs, memory, drives, NICs, PSUs, and cabling: reproduce the failure, isolate the faulty component, and document what proved it

Work servers out-of-band through IPMI and Redfish for power control, boot configuration, BIOS settings, and sensor and event log collection

Apply firmware updates across the fleet following the team's qualified baselines and rollout process

Drive RMAs with vendors from ticket through replacement, installation, and return of the failed part

Keep asset, serial, and replacement history accurate in NetBox so we know what's actually in every rack

Track failure patterns across the fleet and raise them when the same part or firmware version keeps turning up

Improve the runbooks you work from, and script the steps you find yourself repeating

Partner with datacenter operations on hands-on work during turn-ups and expansions

Take part in an on-call and escalation rotation for hardware issues

Who You Are

Required Qualifications

3–6 years in datacenter operations, systems administration, hardware support, or infrastructure engineering

Hands-on experience with enterprise server hardware: component replacement, POST and boot failures, and reading hardware behavior at the rack

Practical experience with BMCs and out-of-band management: IPMI, Redfish, iDRAC, iLO, or equivalent

Strong Linux troubleshooting: boot process, driver and device issues, and diagnostic tools such as {{dmesg}}, {{lspci}}, {{ipmitool}}, and SMART

Comfort reading sensor data, event logs, and thermal and power telemetry well enough to tell a real failure from noise

Working scripting ability in Bash or Python — enough to automate a repetitive task and read someone else's tooling

Experience running hardware RMAs with vendors, or a clear track record of driving issues to closure with outside parties

A methodical troubleshooting habit: you isolate variables, you don't change three things at once, and you can say what evidence led to your conclusion

Clear written communication for tickets, runbooks, and vendor cases

Preferred Qualifications

GPU server experience, especially AMD GPUs and ROCm

Burn-in, stress testing, or node validation tooling in a GPU or HPC environment

Familiarity with firmware update processes and why fleet-wide changes get staged

NetBox or other DCIM and IPAM tooling

Ansible, or Python against REST APIs

Prior work in a high-volume hardware environment: hyperscaler, colo, integrator, or manufacturing test

First Six Months

By 90 days you'll run burn-in cycles and triage failures independently from our runbooks, and you'll have driven at least one RMA to closure. By six months you're the person who spots the pattern before anyone else — this batch, this firmware, this part — and you've automated at least one step you used to do by hand.
