Senior Staff Software Engineer, DC Infrastructure

Senior Staff Software Engineer, DC Infrastructure at crusoe.

About the role Crusoe is on a mission to accelerate the abundance of energy and intelligence. As the only vertically integrated AI infrastructure company built from the ground up, we own and operate each layer of the stack — from electrons to tokens — to power the world's most ambitious AI workloads. When you join Crusoe, you join a team that is building the future, faster.

We are seeking a highly skilled and motivated Software Engineer to join Crusoe’s Data Center Infrastructure Engineering team. This role is focused on the development of software for the management of a fleet of GPU servers as well as the data centers that house those systems. The ideal new team member will be a hands‑on problem solver who is comfortable working independently.

The new team member will play a critical role in maintaining the health and scalability of Crusoe’s rapidly growing GPU fleet. You will own the deployment, monitoring, and operational support of developed tooling, ensuring solutions maximize GPU fleet availability and performance to drive customer success. The team owns deployment maintenance, observability, critical environment management, and automation. You will develop automation and AI agents for executing component‑level diagnosis and remediation for failed or degraded hardware.
