Infrastructure Engineer

Spear AI is seeking an experienced Infrastructure Engineer with expertise in cloud deployments and either experience in on-premise deployments or a willingness to learn. In this role, you will design, deploy, and maintain reliable infrastructure that spans cloud services and on-premise environments. You will collaborate with cross-functional teams to ensure the stability, security, and scalability of our IT infrastructure. Spear AI uses Pulumi for our infrastructure management.

Spear AI servers the national security industry and deploys software to cloud environments that span unclassified, Secret, and Top Secret regions. We also deploy software to the edge in some of the harshest conditions, including US nuclear submarines.

You must be willing to receive a Secret or Top Secret/SCI security clearance. This will be at no expense to you. For resources on what goes into a security background investigation and what disqualifies people reference the CIA requirements. Failure to obtain or maintain a clearance will be grounds for termination.

We hope you'll join our fast growing team!
