We have an opening for a Cloud and Core Network Engineer. You will play a critical role in helping the laboratory seamlessly adopt and operate multi cloud architectures across AWS, Azure, and GCP, with responsibility for cloud governance, management, and security. You will join the Enterprise Network Services team, which designs, deploys, and operates carrier grade networks and cloud networking infrastructure at scale, leveraging Terraform automation in environments with more than 100 AWS accounts and thousands of VPCs to ensure all network components are fully built, deployed, and decommissioned against a Nautobot source of truth. This position is in the Enterprise Infrastructure Services (EIS) Division with the Computing Directorate, in support of LivIT.
This position offers a hybrid schedule, blending in-person and virtual presence. You will have the flexibility to work from home one or more days per week.
This position will be filled at either the SES.3 or SES.4 level based on knowledge and related experience as assessed by the hiring team. Additional job responsibilities (outlined below) will be assigned if hired at the higher level.
You will
- Collaborate with service owners, network engineers, developers, stakeholders, and leadership to develop consensus-based outcomes around cloud infrastructure provisioning, monitoring, management, and troubleshooting.
- Collaborate on the design and architecture of a hybrid, multi-cloud environment, including providing a secure and robust network backbone.
- Design and deliver advanced automation and infrastructure-as-code solutions to streamline provisioning and management of deployed green- and brown-field resources.
- Engage with laboratory scientists, researchers, and developers to understand their workloads and help drive solutions toward cloud-native technologies.
- Draft and maintain architectural documentation and artifacts, including as-builts, runbooks, and demonstration code.
- Stay up to date with the latest industry hybrid network architectures and best practices.
- Present and communicate solutions to technical and non-technical stakeholders.
- Perform other duties as assigned.
Additional job responsibilities, at the SES.4 level
- Independently define, prioritize, and execute the technical roadmap for multi-cloud + data-center networking, translating loosely defined objectives into deliverable architectures, implementation plans, and milestone outcomes.
- Provide expert-level routed network design across AWS/Azure/GCP and on-prem data centers, including routing domain boundaries, segmentation strategy, and failure-domain design to meet long-range reliability, security (PAN), and performance targets.
- Apply expertise in BGP-based connectivity and routing policy (path selection, summarization, route filtering/leak prevention, deterministic failover), validating convergence behavior and preventing asymmetric routing impacts across stateful enforcement points.
