🇧🇷 Datacenter Hardware & Network Support Technician (Remote, from Brazil)

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).
