Associate System Engineer, GreenNode

We are looking for an Associate Systems Engineer to join our Core Infrastructure team. We run high-scale physical and virtual cloud platforms; our focus is the health, efficiency, and resilience of physical and virtualized computing platforms.

We value hands-on system curiosity, diagnostic intuition, and clear analytical thinking. You will work alongside senior and principal engineers to monitor fleet health, optimize compute and storage allocation, triage complex system behaviors, and build engineering-grade technical documentation.

Key Responsibilities:

Systems Diagnostics & Incident Triage:

• Investigate OS and kernel issues, analyze telemetry, system logs, and system calls across our Linux fleet.
• Inspect degraded hardware before complete failure occurs.

• Monitor fleet utilization, workload density, and resource quotas.
• Help manage the operational lifecycle of compute and storage hosts.

• Run performance benchmarks on hardware components and kernel settings.
• Synthesize benchmark data into clear technical evaluation reports.
• Write precise internal runbooks and operational playbooks.
