Requirements
• 5+ years of experience in systems administration, cloud operations, or infrastructure engineering • 3+ years of hands-on experience managing AWS and/or Azure environments, including virtual machine administration • Strong Terraform experience, including modular design and state management; experience leading IaC migrations is a plus • Demonstrated ability to automate operational workflows and reduce manual effort at scale • Strong understanding of IAM, encryption (KMS, TLS), and network segmentation • Experience with Linux (RHEL/Amazon Linux) and/or Windows Server in a cloud context • Familiarity with containerization technologies (Docker, ECS, EKS, or Kubernetes) • Solid understanding of CI/CD pipelines and DevSecOps practices • Must be a US Citizen & all work must be performed in the United States • Multi-cloud experience spanning AWS and Azure • Experience in regulated industries such as healthcare (HIPAA), defense (CMMC/NIST 800-171), or financial services (SOC 2) • AWS certifications (Solutions Architect, SysOps Administrator, Security Specialty) or Azure equivalents • CompTIA Security+ or equivalent security certification • Experience with AWS Control Tower, Landing Zones, or equivalent governance tooling • Familiarity with SIEM platforms (Splunk, Microsoft Sentinel) • Experience managing or mentoring distributed technical teams • PMP, CSM, or similar project/program management certification • Active DoD security clearance (Secret or above) or ability to obtain and maintain one • Core Competencies • Core Competencies • Infrastructure Ownership — takes end-to-end accountability for cloud environment health, security, and performance • Infrastructure Ownership • Automation Mindset — proactively identifies manual processes and replaces them with scalable, repeatable solutions • Automation Mindset • Security-First Thinking — embeds security practices into every layer of infrastructure design and operations • Security-First Thinking • Cross-Functional Communication — translates technical complexity for business and compliance stakeholders • Cross-Functional Communication • Disciplined Documentation — produces clear, audit-ready artifacts without being asked • Disciplined Documentation • Adaptability — comfortable operating across cloud providers, toolchains, and evolving compliance landscapes • Adaptability • What Success Looks Like • Cloud environments (AWS/Azure + EKS) are stable, secure, observable, and documented • Infrastructure changes are repeatable through IaC with clear review and rollback paths • Monitoring/logging and vulnerability remediation are routine—not scramble-driven • Audit support artifacts (diagrams/runbooks/evidence) are kept current and usable
Responsibilities
• Cloud Infrastructure & Virtual Systems Administration • Administer and maintain AWS and/or Azure environments, including day-to-day operations of virtual machines, networking, and storage. • Manage VPCs, subnets, routing tables, security groups, NACLs, and private networking constructs • Deploy, maintain, and optimize EC2 instances, RDS, S3, IAM, KMS, Secrets Manager, and CloudTrail • Build and manage hardened VM images (AMIs / golden images) for consistent, repeatable deployments • Implement and support high availability, auto-scaling, and disaster recovery configurations • Support multi-account or multi-subscription cloud governance structures (e.g., AWS Organizations, Azure Management Groups) • Infrastructure as Code (IaC) • Design and maintain infrastructure using Terraform, including modular design, remote state management, and workspace strategies • Lead or support migrations from legacy IaC tooling (e.g., CloudFormation) to modern frameworks • Enforce policy-as-code guardrails and maintain version-controlled infrastructure repositories • Build reusable, secure baseline modules for VPC architecture, IAM roles, logging, monitoring, and encryption • Virtualization & Containerization • Administer virtualized workloads across cloud environments, including sizing, patching, lifecycle management, and cost optimization • Support container-based workloads in ECS and/or EKS, including cluster management, networking, and image security • Assist with transitions from legacy compute paradigms (e.g., EBS-backed instances) to modern container or serverless architectures • Implement automated drift detection and remediation for both VMs and containerized environments • Automation & DevSecOps Integration • Identify and implement automation opportunities to reduce manual operational overhead and improve team velocity • Integrate infrastructure provisioning and security controls into CI/CD pipelines (GitHub Actions, GitLab CI, or equivalent) • Implement and maintain secure secrets management practices • Collaborate with DevSecOps and application engineering teams to enforce least-privilege IAM policies and secure-by-default configurations • Security, Compliance & Monitoring • Configure and monitor AWS CloudTrail, GuardDuty, Security Hub, Config, and centralized logging pipelines • Support SIEM integration (e.g., Splunk, Microsoft Sentinel) and assist with incident response • Maintain vulnerability management lifecycle including patching, remediation tracking, and reporting • Support compliance efforts aligned with relevant frameworks (NIST 800-171, CMMC, HIPAA, SOC 2, or FedRAMP as applicable) • Cross-Functional Collaboration & Documentation • Partner with development, security, and IT operations teams to deliver reliable, scalable services • Produce and maintain thorough documentation — architecture diagrams, runbooks, SOPs, and evidence artifacts for audits or assessments • Contribute to budget management, resource planning, and capacity forecasting for cloud environments
Benefits
• A fully remote, results-based environment • Competitive salary, bonus, and equity package • 100% employer paid, comprehensive health insurance including medical, dental, and vision for you and your family • Unlimited PTO, with your manager’s approval • Flexible work environment where you manage your work day • 14 weeks of fully-paid parental leave • Salary Range: $140,000-$180,000.
