We are excited to announce that we have an opening in our Clarksburg, MD office for a Senior Cloud Engineer, reporting to the Senior Manager, Network Operations. The Senior Cloud Engineer will design, build, and operate secure, cost-efficient cloud infrastructure as we expand our presence in Microsoft Azure (primary) and AWS. This role places strong emphasis on cloud cost and budget management, networking/hybrid connectivity, security, and operational excellence in a regulated DOD contractor environment.

Responsibilities

Design, deploy, and maintain secure, scalable cloud infrastructure primarily on Microsoft Azure (with secondary AWS support) for enterprise and mission-supporting workloads.
Engineer and operate core cloud services: compute (IaaS VMs), storage, virtual networking (VNets/VPCs, subnets, NSGs/security groups, load balancers), and hybrid connectivity to on-premises environments.
Own cloud cost management and optimization — track spending, implement tagging and budgeting controls, identify waste, and drive continuous cost efficiency while meeting performance and security requirements.
Implement and manage identity & access (Entra ID / IAM), RBAC, and least-privilege models aligned with DoD and company security policies.
Automate infrastructure and operational tasks using PowerShell, Python, Bash, and cloud-native tools; support integration with existing CI/CD or DevOps pipelines where applicable.
Monitor performance, availability, security posture, and cost using Azure Monitor, AWS CloudWatch, native security tools, and enterprise monitoring/ticketing platforms.
Support backup, snapshot, and disaster recovery solutions that meet business continuity and data protection needs.
Partner with security, network, systems, and application teams to deliver integrated hybrid solutions and resolve escalated issues.
Ensure ongoing compliance with DoD requirements (FedRAMP, NIST SP 800-53, CMMC, Cloud Computing SRG, STIGs where applicable) and support related audits and assessments.
Provide incident response, root-cause analysis, and technical support via Jira Service Management (or equivalent); communicate status clearly to stakeholders.
Create and maintain clear documentation, architecture diagrams, runbooks, and SOPs.
Lead or support on-premises to cloud migrations (including Nutanix and Windows Server environments) with minimal disruption.
Contribute to cloud governance, capacity planning, cost forecasting, and technology roadmaps; serve as a cloud SME within IT.
Work with leadership and business stakeholders to translate requirements into practical, secure cloud solutions.
