About Nscale
Nscale is the GPU cloud engineered for AI. We provide cost-effective, high-performance infrastructure for AI start-ups and large enterprise customers. Nscale simplifies AI development while enabling superior results, supporting strategic business outcomes such as cost management, rapid innovation, and environmental responsibility.
We thrive on a culture of relentless innovation, ownership, and accountability, where every team member takes pride in their work and drives it with excellence and urgency. As an Nscaler, you’ll build trust through openness and transparency while contributing to the technology that powers the future.
About the role
The Network Operator keeps Nscale’s network available, fast and secure around the clock. You will monitor network health, resolve incidents before they affect customers, and carry out planned changes safely.
As a senior operator, you work independently on most issues, act as the escalation point for junior operators, and partner with network engineering on complex problems. You are the kind of technician focused on moving fast, staying humble, and taking full ownership of any issues that arise to ensure we achieve the best outcome.
