About Us:
Sealing Technologies, a Parsons company, innovates and delivers high-performance deployable anywhere technologies that push what's possible at the edge, enabling organizations across the globe to solve complex challenges with speed and confidence. We design, engineer, and deliver products and deployable technologies built for environments where traditional infrastructure falls short.

Position Overview:
Sealing Technologies, a Parsons Company, is looking for an experienced DevOps Engineer to join a growing Software Development project team. In this role, you will develop and maintain the automation and deployment infrastructure that underpins a consolidated application suite supporting Defensive Cyber Operations (DCO). The suite runs on custom server hardware and is built to operate in fully offline, disconnected environments with no reliance on cloud services.

You will work across the full deployment lifecycle, automating Kubernetes cluster provisioning, containerizing applications, managing KubeVirt virtual machines, and building the CI/CD pipelines that keep the team moving. You will collaborate closely with systems engineers, contribute to documentation, and take on a range of tasks as the product and mission evolve. The ideal candidate is someone who is comfortable wearing multiple hats, picks things up quickly, and takes ownership across disciplines.

Duties and Responsibilities:

Develop and maintain Ansible playbooks and roles to automate the deployment and configuration of Kubernetes clusters, containerized workloads, and KubeVirt VMs on custom server hardware.
Containerize applications and manage container image builds, versioning, and distribution in offline environments.
Build and maintain CI/CD pipelines using GitLab CI and/or GitHub Actions to support iterative software delivery across multiple products.
Work closely with systems engineers to understand hardware and environmental constraints and translate them into repeatable, automated deployment processes.
Troubleshoot deployment, networking, storage, and configuration issues across the full application stack in air-gapped environments.
Assist with the integration of application data streams into big data platforms, supporting pipeline tooling such as Apache NiFi or similar ETL frameworks.
Contribute to system hardening and STIG compliance activities as part of deployment and configuration workflows.
Write and maintain clear technical documentation including deployment guides, runbooks, and architecture notes.

Minimum Qualifications:

U.S. Citizenship.
Active SECRET security clearance.
6+ years of professional experience in DevOps, systems engineering, or a closely related field.
Strong hands-on experience with Kubernetes, including cluster setup, workload deployment, networking, and day-to-day troubleshooting.
Solid Linux system administration skills, including networking, storage, and service management across multiple distributions.
Demonstrated experience writing and maintaining Ansible playbooks and roles for infrastructure automation and application deployment.
Experience building and managing CI/CD pipelines with GitLab CI and/or GitHub Actions.
Hands-on experience containerizing applications using Docker or similar tooling.
Ability to work effectively in offline or air-gapped environments without access to public registries or cloud services.
Strong written communication skills and experience producing clear technical documentation.

Preferred Qualifications:

Experience with KubeVirt or managing VM-based workloads within Kubernetes.
Experience deploying software to bare-metal or custom server hardware outside of traditional data center or cloud environments.
Experience with data stream integration and ETL tooling such as Apache NiFi, Kafka, or Logstash for ingesting application data into big data platforms.
Familiarity with cybersecurity tooling or security operations platforms such as Elastic, Splunk, or Security Onion.
Experience working in Federal or DoD environments, including STIG compliance and system hardening practices.
Familiarity with Helm for Kubernetes application packaging and deployment.
