Remote Devops Jobs in Ohio (NOW HIRING)

ARS is seeking an experienced Senior DevOps Engineer to design, deploy, and sustain a DevSecOps platform-as-a-service for a U.S. Government customer within an Azure environment. This role is responsible for building and optimizing CI/CD pipelines in cloud settings, managing Azure infrastructure via Infrastructure as Code (IaC), and supporting automation of customer development desktops and enterprise workloads. The Senior DevOps Engineer will enforce security compliance, support customer onboarding, and provide Tier 3 operational support. This position requires the ability to obtain a Secret clearance.

The Senior DevOps Engineer is a highly specialized technical role operating at the intersection of cloud infrastructure, DevSecOps automation, and government compliance. This position requires an engineer with deep hands-on experience deploying and maintaining complex Azure infrastructure.

This engineer will own the full infrastructure automation lifecycle using Bicep and Terraform, build and maintain golden image pipelines, and ensure all environments adhere to DoD security standards including STIG/SCAP, WSUS patching, and vulnerability management via Nessus Security Center. Critically, this is a hands-on engineering role, not an architecture or governance position. Candidates must be able to write and deploy production-grade IaC, build pipelines end-to-end, and operate confidently in restricted, offline environments.

The engineer will work under the technical direction of a Chief Architect and collaborate closely with onsite and remote teams to validate configurations, onboard customers, and ensure handoff readiness. Strong documentation practices in Confluence and comfort navigating government change management processes are essential.

• Deploy Azure infrastructure via established CI/CD pipelines into enterprise environments.
• Document customer configurations and operational details in Confluence.
• Coordinate with onsite and remote teams to validate configurations and ensure handoff readiness.
• Provide Tier 1 operational support, including automated baseline desktop and software installs (DSC, Packer).

Automation & Container Enablement

• Develop and maintain automation solutions using Bicep and/or Terraform to minimize manual intervention and improve deployment reliability.
• Support container image movement and lifecycle management using tools such as Skopeo, Crane, and Podman, ensuring secure and repeatable container workflows.
• Architect, develop, automate, deploy, and manage AKS-based applications to support developers.
• Other duties as assigned

Required Qualifications:

• Must be a U.S. citizen
• Active Security+ Certification (or equivalent DoD 8570 IAT Level II certification)
• Ability to obtain a Secret clearance
• 8+ years of demonstrated performance in related technology
• Hands-on experience deploying Microsoft infrastructure using Terraform or Bicep
• Bachelor's degree in Computer Science, Engineering, or related field AND 3+ years of technical leadership experience OR equivalent experience

• Technical certifications in Azure (e.g., Azure Solutions Architect, Azure DevOps Engineer Expert)
• Experience working in regulated, compliance-driven, or DoD government environments
• Familiarity with DoD Risk Management Framework (RMF) and ATO processes
• Experience with Kubernetes and AKS in production environments
• Experience with Packer, Skopeo, Crane, or Podman in enterprise container workflows
• Familiarity with Keycloak or Entra ID federation/SSO in classified environments

Key Differentiators for Success:

• Proven ability to personally write and deploy production-grade IaC, not just govern or review it
• Demonstrated experience operating in SCIFs or air-gapped environments where internet access is unavailable
