Staff Systems Engineer, Microsoft Infrastructure at Crusoe · LumiJobs

Responsibilities

We're hiring a Staff Systems Engineer, Microsoft Infrastructure to own Crusoe's corporate IT infrastructure end to end: the servers, virtualization, storage, networking, and cloud platforms that keep our offices, warehouses, manufacturing (CI) facilities, and data centers running. This is a hands-on individual contributor role. You will personally build, migrate, and support servers, and you will be the escalation owner when infrastructure breaks.
At the staff level, you also set the direction. You'll own the infrastructure roadmap, prioritize across projects, and work directly with business stakeholders to understand requirements before you build. Some of our hardest problems sit here: moving specialized applications, such as manufacturing software with licensing tied to physical hardware, off on-prem servers and into the cloud when the vendor never designed them to run there.
What You'll Be Working On:
Manage and modernize Windows Server environments—including Active Directory, DNS/DHCP, Group Policy, certificate services, and file infrastructure—across Hyper-V, VMware, and bare-metal systems
Drive on-premises to multi-cloud server migrations (Azure, GCP, AWS), navigating complex software dependencies, restrictive vendor licensing, and legacy workloads
Architect and operate core compute, storage, and server networking resources, collaborating with Network Engineering on site connectivity and infrastructure deployments
Deploy Azure Arc to standardize governance, security policies, and operational monitoring across hybrid server environments
Design and maintain IaC configurations using Terraform, Bicep, or ARM templates to enable auditable, version-controlled automation
Oversee Microsoft 365 and Entra ID tenant health, securing access via Conditional Access and MFA while managing Okta identity federation
Lead system monitoring, backups, disaster recovery strategies, and incident response, acting as the primary escalation point during on-call rotations
Execute hands-on physical server deployment—racking, cabling, and provisioning—at corporate offices, data centers, and manufacturing facilities, requiring occasional site travel
Establish infrastructure roadmaps and technical standards, managing priorities while ensuring compliance with SOC 2 and SOX controls
