You will work under the guidance of senior engineers and travel to US data center sites to support new deployments, troubleshooting, and bring-up activities. This is an ideal role for someone with homelab and/or internship experience who is eager to learn enterprise-scale infrastructure from the ground up., Virtualization & Compute Deployment
Install, configure, and maintain Proxmox hypervisors on bare-metal servers during data center deployments
Provision and manage virtual machines, including resource allocation, templates, and standardized deployment profiles
Perform routine patching, upgrades, and lifecycle maintenance of hypervisor hosts and guest VMs
Assist with server imaging, initial configuration, and validation during site bring-up

Network Deployment & Operations
Assist senior engineers with the deployment and initial configuration of BGP routers at new data center sites
Rack, cable, and configure out-of-band (OOB) management fabrics using Unifi or NVIDIA switches
Assist in building and validating RDMA compute fabrics, primarily RoCEv2, with opportunities to gain InfiniBand experience
Perform basic switch and router configuration tasks (VLANs, IP assignments, port configuration) under senior guidance
Help with cable management, labeling, and physical layer troubleshooting during deployments
Learn and apply IP addressing, subnetting, and IPAM documentation practices
Monitor network and infrastructure health using observability tools and escalate issues appropriately
Participate in a supported on-call rotation after an onboarding/ramp-up period

Automation & Tooling
Assist in developing and maintaining automation using Python and/or Ansible for provisioning, configuration, and routine operational tasks

Identify repetitive manual tasks that are candidates for automation

Collaboration & Documentation
Travel to data center locations within the US to support deployments, troubleshooting, and site bring-up (regular travel expected)
Maintain accurate documentation including runbooks, network diagrams, deployment procedures, and configuration records
Work closely with deployment engineers and operations teams during infrastructure builds
Learn from senior engineers through mentorship, pairing, and hands-on deployment work

Safety & Compliance
Adhere to strict data center safety protocols and operational standards during all on-site activities
Follow security best practices for system and network configuration and access control
Participate in regular safety training and briefings
