• At least 8 years of cloud, platform, systems, or DevSecOps engineering experience, including at least 3 years delivering production platform automation.
• Hands-on Azure or Azure Government experience with networking, compute, storage, identity integration, policy, monitoring, and secure configuration.
• Strong infrastructure-as-code experience with Terraform, Bicep/ARM, Ansible, or equivalent, including module design, state and change management, testing, and peer-reviewed promotion.
• Experience building or operating CI/CD and artifact/container services within enterprise or disconnected boundaries, using platforms such as GitLab, Jenkins, Nexus/Artifactory, Harbor, Kubernetes/OpenShift, or comparable tools.
• Strong Linux and Windows administration fundamentals and proficiency in Python, PowerShell, Bash, or another automation language.
• Experience with container hardening, image and dependency scanning, SBOMs, secrets management, certificate handling, and rollback and recovery.
• Working knowledge of RMF/STIG controls, change management, operational acceptance, logging and audit, and classified data-handling requirements.
• Ability to lead technical work, review others' code and designs, communicate risk early, and remain calm during production issues.

Nice To Haves

• Azure Administrator Associate or DevOps Engineer Expert certification and a relevant Terraform certification.
• Experience supporting GPU/AI platforms, ML model artifacts, offline Python wheelhouses, or local inference services.
• Experience integrating ServiceNow change/CMDB records with pipeline and deployment events.
• Experience with policy-as-code, compliance-as-code, infrastructure testing, chaos/resilience testing, or FinOps automation.

Responsibilities

• Implement Azure platform services, landing-zone components, network integration, policy, logging, identity hooks, key and secrets management, and workload hosting patterns under the Principal Cloud Architect's direction.
• Develop and maintain version-controlled infrastructure-as-code modules using Terraform, Bicep/ARM, Ansible, or approved equivalents, with peer review, testing, and disciplined releases.
• Build and operate internal GitLab/Jenkins or equivalent pipelines, container platforms, registries, package and image repositories, and artifact mirrors for disconnected delivery.
• Implement software supply-chain controls, including SBOM generation, dependency and image scanning, signing, provenance, allowlists, and promotion gates.
• Develop hardened container images, deployment templates, configuration standards, and environment-specific overlays for applications, data services, and AI inference workloads.
• Automate platform provisioning, patching, backup, recovery, certificate and secret rotation, compliance checks, and routine operations.
• Integrate platform telemetry with Azure Monitor, Sentinel, Dynatrace, ServiceNow, and the enterprise observability architecture.
• Partner with Security and RMF staff to implement controls and produce reusable evidence from code, pipeline, scan, and configuration outputs.
• Troubleshoot complex platform failures, lead technical recovery when assigned, document root causes, and translate lessons into platform improvements.
• Mentor engineers, conduct code and design reviews, and help domain teams adopt approved platform patterns instead of building shadow infrastructure.
