Livermore, CA, USA Hybrid Full-time USD 175,530 – 267,060 / year

Lawrence Livermore National Laboratory (LLNL) is hiring a Cloud and Core Network Engineer

Responsibilities

  • Work with service owners, network specialists, developers, and leadership to align on cloud infrastructure strategies for provisioning, monitoring, operations, and issue resolution.
  • Contribute to the planning and structure of hybrid, multi-cloud systems with an emphasis on secure and resilient network foundations.
  • Develop and implement advanced automation and infrastructure-as-code methods to simplify deployment and management of new and existing infrastructure.
  • Partner with scientists, researchers, and software developers to assess workload requirements and guide adoption of cloud-native platforms.
  • Create and sustain technical documentation such as architecture diagrams, operational runbooks, and sample implementation code.
  • Maintain current knowledge of evolving hybrid network designs and standard industry practices.
  • Explain technical solutions clearly to both technical teams and non-technical decision-makers.
  • Carry out additional assigned tasks as needed.
  • Independently establish, rank, and advance the networking strategy for integrated multi-cloud and data center environments, turning high-level goals into actionable designs and milestones.
  • Deliver expert routed network designs across public cloud platforms and on-premises data centers, ensuring alignment with long-term reliability, security, and performance requirements.
  • Apply deep understanding of BGP connectivity and routing policies—including path control, summarization, filtering, leak prevention, and failover—to ensure predictable behavior and avoid routing issues across stateful security layers.

Requirements

  • Familiarity with cloud governance, operational management, and security protocols across AWS, Azure, and GCP environments.
  • Proven background using Terraform for automation in complex, large-scale deployments such as environments with over 100 AWS accounts and thousands of VPCs.
  • Capacity to work effectively with service owners, engineers, developers, and stakeholders to reach agreement on infrastructure approaches.
  • Experience building and deploying automated systems and infrastructure-as-code solutions.
  • Skill in writing and updating architectural records, operational guides, and demonstration scripts.
  • Strong communication abilities for conveying technical solutions to diverse audiences.
  • Knowledge of hybrid network design principles and widely accepted industry standards.

Nice to Have

  • Demonstrated ability to independently shape, prioritize, and drive technical strategies for networking across multi-cloud and on-prem data center environments.
  • Advanced proficiency in routed network design across AWS, Azure, GCP, and on-prem facilities, including routing segmentation, domain boundaries, and failure zone planning.
  • Extensive experience with BGP-based routing, including path selection, summarization, filtering, leak prevention, and deterministic failover mechanisms.
  • Background in validating network convergence and addressing asymmetric routing challenges across stateful security enforcement points.
