Context
AS+ provides run support for GPU clusters operated by a cloud infrastructure partner. We are building a support team to handle day-to-day incidents on these clusters. This first role focuses on weekday coverage. The work sits low in the stack — hardware and network diagnosis — rather than high-level HPC or application support.

Responsibilities

• Diagnose and triage incidents on GPU compute clusters, determining whether a fault originates on our side or the client's.

• Investigate hardware failures: collect and analyze hardware logs, identify failed components, and document findings for resolution or RMA.

• Diagnose GPU hardware faults (failure detection and isolation — not performance tuning or porting).

• Configure and troubleshoot network connectivity, including InfiniBand fabric.

• Work directly with the client as first line of support, in English.

Required skills

• Solid system and network fundamentals — low-level networking and connectivity diagnosis.

• Hands-on hardware troubleshooting, ideally on Dell server hardware.

• Ability to diagnose GPU hardware failures (no deep GPU expertise required).

• InfiniBand knowledge (important).

• Fluent English (all client communication is in English).

Not required

• No advanced OS administration.

• No Slurm or workload-scheduler expertise.

• No HPC application or GPU-porting background.

Setup

• Full remote.

• Weekday coverage (first hire; the team will expand to cover a wider window).
