About The Position

As a Senior Platform Engineer, you will build and operate the hybrid infrastructure behind a Digital Twin and Modeling & Simulation platform for military test ranges. The environment spans AWS GovCloud and VMware-based on-premises and disconnected settings. You will design, automate, and maintain the networking, storage, and Kubernetes foundations that support simulation, visualization, and data-processing workloads across cloud and range environments. Working with DevOps engineers, backend developers, and solution architects, you will help keep the platform secure, repeatable, and ready for accreditation in regulated DoD environments. The role involves solving hybrid-cloud challenges related to workload portability, network connectivity, hardening, and lifecycle management, while developing skills in enterprise virtualization and cloud-native technologies. The selected applicant will be subject to a security investigation and may need to meet eligibility requirements for access to classified information.
