If you'd like to build the world's best AI cloud, join us.
This position is expected to participate in an on-call rotation.
What You’ll Do
-
Serve as a senior technical escalation point, troubleshooting the hardest infrastructure and platform issues down to the hardware, driver, or kernel level when needed
-
Quickly and accurately distinguish between hardware failures, driver issues, kernel-level problems, and customer workload misconfiguration, so issues get resolved correctly the first time
-
Proactively identify process, tooling, and documentation gaps, and go fix them, not just wait for them to be assigned
-
Use AI tools effectively to build scripts, automations, or small internal tools that close real operational gaps (no professional development background required)
-
Perform root-cause analysis across distributed systems, clusters, and GPU infrastructure
-
Craft clear documentation of solutions and contribute to evolving support procedures
-
Collaborate closely with engineering teams to turn recurring customer pain points into permanent fixes
-
Take escalations from peers while training and mentoring them in the process
-
Participate in a rotating on-call schedule, owning major incidents and major customer issues
-
Be ready to roll up your sleeves and pitch in wherever needed, especially during fast, high-volume deployments
