IonQ is building quantum computers at College Park, and the infrastructure underneath that work is a crucial component. A misconfigured VLAN or a failed provisioning job can stop a calibration run or delay a system build. We are looking for a Senior Systems and Network Engineer to own the classical infrastructure layer that directly supports quantum hardware builds and operation at our College Park site.

This means provisioning the servers and system heads that control quantum hardware, building and maintaining the lab and datacenter networking those systems run on, and integrating the cameras, laser control systems, and other bespoke scientific hardware that make a quantum system work. This is lab-grade systems and network engineering: closer to research computing at a national facility than to corporate IT.

You will spend your time with real hardware, real cabling, and real failure modes, and automation of infrastructure to help us continue to scale.

• Provision Linux servers and system heads for quantum hardware builds, including PXE boot, OS installation, and automated configuration
• Build and maintain infrastructure-as-code for server and network provisioning (Ansible, Kickstart, Foreman, Packer, Terraform, or equivalent), so systems are reproducible rather than hand-tuned
• Design, configure, and troubleshoot networking for lab and datacenter environments: VLANs, managed switches, firewalls, and structured cabling
• Integrate non-standard scientific and lab hardware into the compute environment, including cameras, laser control systems, and custom device drivers
• Use IPMI/BMC and other out-of-band tooling to manage a growing fleet of servers without physical intervention on every failure
• Define and document handoff criteria for when a system is ready to…
