How to Apply for Platform Administrator - Kubernetes (Remote)

at Argonne National Laboratory

🏢 About Argonne National Laboratory

Argonne National Laboratory is a premier U.S. Department of Energy research center driving groundbreaking discoveries in climate solutions and sustainable technologies. Working here means contributing to mission-critical scientific advancements that address global challenges, with access to world-class supercomputing facilities like the ALCF (Argonne Leadership Computing Facility). The remote nature of this role offers flexibility while supporting high-impact research infrastructure.

About This Role

This Platform Administrator role focuses on managing on-premise Kubernetes clusters that support scientific workflows in a production environment at ALCF. You'll design administration workflows for cluster upgrades, user application deployment, and incident response while integrating this infrastructure into the facility's ecosystem. Your work directly enables researchers to run complex simulations and analyses for climate and sustainability projects.

💡 A Day in the Life

A typical day involves monitoring and maintaining on-premise Kubernetes clusters supporting active scientific research, troubleshooting deployment issues for user applications, and implementing administration workflows for cluster upgrades. You'll collaborate with ALCF operations teams to integrate Kubernetes infrastructure with the facility's ecosystem while responding to incidents that could impact ongoing research workflows.
