## Description

Parallel Works is hiring a Junior HPC Applications Engineer to support the researchers and engineers running work on our platforms. The role handles first line support: build failures, batch script problems, environment issues, and the first diagnosis on failed jobs.

It suits someone who has run scientific or machine learning workloads on a cluster as a user and wants to move to the other side of the ticket. Our users work across on-premises clusters, cloud, and commercial GPU providers, and the same question often has a different answer in each. The role works alongside a senior applications engineer, building software stacks for users and handling second tier diagnosis after about a year.
What you will do

 * First line support: own incoming tickets, reproduce the problem, resolve what you can, and escalate the rest with a diagnosis attached.
 * Batch scripts: write, debug, and tune Slurm submission scripts with users, including GPU requests, array jobs, and resource sizing.
 * Environments and modules: build and install user requested software under senior review, and maintain module and container environments.
 * Onboarding: walk new users through access, storage layout, and first jobs when a cluster comes online.
 * Documentation: user guides and FAQ entries that cut repeat tickets.
 * Coverage rotation: a support coverage rotation. Some engagements carry coverage outside standard United States business hours, agreed in advance.
