• Containerization and Kubernetes: Deploy, configure, troubleshoot, and maintain containerized applications and orchestration platforms, including Docker, Kubernetes, Amazon EKS, and Azure AKS.
• DevSecOps and CI/CD: Develop, maintain, and troubleshoot automated build and deployment pipelines using GitLab, GitHub Actions, Jenkins, Azure DevOps, and related technologies.
• Cloud Security and Compliance: Implement secure cloud configurations, identity and access controls, encryption, vulnerability remediation, and automated security scanning aligned with NIST SP 800-53, FedRAMP, DoD STIGs, and applicable federal requirements.
• Cloud Operations and Sustainment: Support day-to-day operations, patching, monitoring, incident response, troubleshooting, and root cause analysis across mission-critical cloud environments.
• Cloud Modernization: Support application migrations, cloud landing zones, infrastructure modernization, virtualization, and hybrid cloud integration.
• Monitoring and Logging: Configure and maintain monitoring, logging, and alerting solutions using AWS CloudWatch, Azure Monitor, Splunk, Prometheus, Grafana, and related enterprise tools.
• Technical Documentation: Develop architecture diagrams, deployment procedures, automation scripts, operational runbooks, and standard operating procedures.
• Technical Leadership: Provide technical guidance and mentorship to junior engineers, participate in engineering reviews, support complex troubleshooting, and contribute to engineering standards and best practices.
• Cross-Program Support: Collaborate with MDEC engineers, program teams, customers, and vendors to deliver technical solutions across multiple federal and DoD programs.
• Candidates must facilitate communication between stakeholders and lead engineering discussions.

Required Qualifications:

• Bachelor's degree in Computer Science, Information Technology, Engineering, or a related field with 8+ years of relevant experience, or a master's degree with 6+ years of experience. Additional relevant experience may be considered in lieu of a degree.
• 5+ years of hands-on experience designing, deploying, administering, and supporting cloud infrastructure.

• Experience developing and maintaining Infrastructure as Code using Terraform, Ansible, CloudFormation, or similar technologies.
• Experience implementing and supporting CI/CD pipelines using GitLab CI/CD, GitHub Actions, Jenkins, Azure DevOps, or equivalent tools.
• Hands-on experience with Docker, Kubernetes, or cloud-managed container platforms such as EKS or AKS.
• Strong understanding of cloud networking, including VPCs, VNets, subnets, routing, firewalls, security groups, load balancers, and VPN connectivity.
• Experience administering and troubleshooting Linux and Windows Server environments.
• Experience scripting and automating tasks using Python, Bash, PowerShell, or similar languages.
• Understanding of cloud security, IAM, vulnerability management, encryption, logging, and monitoring.
• Experience troubleshooting cloud infrastructure, networking, and platform issues in operational environments.
• Ability to work independently, manage competing priorities, and support multiple engineering efforts.
• Strong written and verbal communication skills, including experience working with customers, engineers, and technical leadership.
• Must reside within commuting distance of Reston, VA and be able to support a hybrid work schedule.

Clearance Requirements:

• Active DoD Top Secret (TS) clearance with the ability to obtain SCI eligibility prior to the start date, or an active TS/SCI clearance.
• Ability to meet additional security and access requirements associated with assigned programs.

Preferred Qualifications:

• Experience supporting DoD, Intelligence Community, or federal government cloud environments.
• Hands-on experience with AWS GovCloud, Azure Government, OCI Government, or other regulated cloud environments.
• Experience supporting DoD Impact Levels IL4, IL5, or IL6.
• Experience with multi-cloud environments, shared cloud services, cloud landing zones, and managed cloud offerings.
• Experience with cloud migration, application modernization, and hybrid cloud architectures.
• Familiarity with Risk Management Framework (RMF), Authority to Operate (ATO), NIST SP 800-53, FedRAMP, and DISA STIG requirements.
• Experience with security and vulnerability management tools such as Tenable, Splunk, Prisma Cloud, or equivalent solutions.
• Experience with Infrastructure as Code security scanning, configuration compliance, and automated remediation.
• Relevant cloud certifications such as AWS Solutions Architect, AWS SysOps Administrator, Azure Administrator, Azure Solutions Architect, or equivalent.
