Sr Windows Server DevOps Engineer

A3 Technology, Inc. is seeking a senior level Windows Server DevOps Engineer to join our team in Washington, DC.

Essential Job Functions:

Own Windows Server production operations (day one). Serve as the senior technical owner for a predominantly Windows Server environment (~95% Windows), providing hands-on production support for mission-critical applications hosted in government cloud (AWS GovCloud).

Administer and sustain Windows Server. Maintain, troubleshoot, patch, harden, and recover Windows Server systems in production — sustaining availability during business hours and through a shared on-call rotation, independently resolving after-hours incidents.

Take ownership of Kubernetes. Independently operate and troubleshoot the Kubernetes environment (EKS), resolving complex cluster, workload, and platform issues and supporting existing production applications and workloads.

Lead incident response. Drive production incident response and deep-dive root-cause analysis across Windows Server, cloud, and container platforms.

Engineer secure cloud infrastructure. Design, implement, and maintain secure, scalable cloud architectures across Windows and Linux systems; work independently or lead small teams.

Automate with IaC (secondary). Develop and manage Infrastructure as Code using Terraform and Ansible to provision and configure environments — secondary to Windows operations and Kubernetes troubleshooting.

Build CI/CD and DevSecOps. Develop and maintain CI/CD pipelines and DevSecOps automation aligned with government and industry best practices.

Monitor and ensure availability. Design and implement monitoring, logging, and alerting solutions; establish performance baselines and ensure system availability.

Harden federal environments. Enforce security best practices, including identity and access management and system hardening for federal environments.

Document and mentor. Develop and maintain technical documentation, runbooks, and SOPs; mentor junior and mid-level engineers and provide technical leadership across DevOps practices.

Required Skills:

Windows Server operations — highest priority. Strong, current, hands-on Windows Server administration/engineering: production support, troubleshooting, maintenance, recovery, and patching. The environment is approximately 95% Windows.

Current Kubernetes expertise. Able to independently operate, troubleshoot, and take ownership of a production Kubernetes environment and answer senior-level Kubernetes questions.

Day-one senior contributor. Demonstrated ability to perform at a senior level immediately with minimal or no ramp-up; practical production operations experience rather than primarily cloud-native development.

On-call readiness. Willing and able to participate in a production on-call rotation and independently resolve after-hours incidents.

Minimum 10 years of relevant IT/engineering experience, including senior-level Windows Server operations and 3+ years supporting cloud engineering environments.

Government cloud. Strong hands-on experience with AWS GovCloud.

Bachelor's degree (BA/BS) in Computer Science, Information Systems, Engineering, or related field; a Master's degree may substitute for additional years of experience per contract guidance.

Core skills. Ability to work independently with minimal supervision in complex, secure environments; strong analytical and advanced troubleshooting skills; excellent written, verbal, and stakeholder communication; demonstrated technical leadership and mentoring.

Ability to obtain and maintain a Federal Public Trust (or higher); candidates with an active clearance strongly preferred.

Preferred Skills:

Windows automation & certs. PowerShell scripting; Microsoft / Windows Server Administrator certifications.

IaC depth. Deep Terraform (Infrastructure as Code) and Ansible (configuration management/automation) expertise.

Kubernetes at scale. Service mesh, API gateways, and Kubernetes security tooling.

Federal compliance. Experience with FISMA, NIST, and FedRAMP frameworks.

Cloud certifications. AWS Certified DevOps Engineer.

Security adjacencies. Familiarity with PKI, identity services, or credential management systems.

Enterprise scale & scripting. Experience supporting large-scale, multi-environment enterprise systems; scripting in Python and Bash.

Education:

BA/BS in Computer Science, Information Systems, Business, or equivalent field and 10 years of related experience with 3+ years in cloud engineering support.
