DevSecOps Engineer

Core4ce is hiring a Senior Dev Sec Ops  Engineer to support a large, secure Department of Defense (DoD) healthcare cloud environment. This is a fully remote, hands-on engineering position responsible for engineering, automating, securing, maintaining, and troubleshooting enterprise container platforms and the Dev Sec Ops  technologies that support them.

The ideal candidate will have deep, demonstrated Kubernetes experience, preferably including Red Hat Open Shift, along with strong Infrastructure as Code (IaC), CI/CD, Linux, cloud, automation, and troubleshooting skills.

This position requires more than expertise with individual tools. The successful candidate will understand how the components of a modern Dev Sec Ops  platform work together and will be capable of troubleshooting complex problems across Kubernetes, Linux, cloud infrastructure, networking, security, identity, CI/CD pipelines, and application workloads.

Strong communication and customer interaction skills are essential. This engineer will work directly with application teams and other customers to understand requirements, resolve technical issues, and help teams successfully deploy and operate applications within the Dev Sec Ops  environment.

As a senior member of the engineering team, this individual will also be expected to provide advanced technical input and mentor less experienced engineers.

• Engineer, administer, maintain, upgrade, secure, and troubleshoot enterprise Kubernetes and Red Hat Open Shift environments supporting development, staging, and production workloads.
• Develop and maintain Infrastructure as Code (IaC) and configuration automation using technologies such as Terraform and Ansible/Ansible Automation Platform.
• Design, develop, maintain, and troubleshoot CI/CD pipelines supporting automated software build, testing, security scanning, artifact management, and deployment.
• Troubleshoot complex technical problems spanning Kubernetes/Open Shift, Linux, cloud infrastructure, networking, DNS, certificates, authentication, storage, containers, CI/CD pipelines, and application workloads.
• Work directly with customers and application teams to understand technical requirements, identify pain points, evaluate solutions, and resolve platform and application deployment issues.
• Implement and support security throughout the software delivery lifecycle, including vulnerability scanning, container security, secrets management, artifact security, software supply-chain security, and Software Bills of Materials (SBOMs).
• Support vulnerability remediation, system hardening, cybersecurity compliance, and authorization/accreditation activities.
• Support container registries, artifact repositories, identity and access management, security scanning, and related Dev Sec Ops  platform services.
• Monitor and optimize system resources, including performance, capacity, availability, serviceability, and recoverability.
• Develop and maintain technical documentation, system administration procedures, troubleshooting guides, engineering standards, and standard operating procedures.
• Participate in system architecture, platform modernization, and technology evaluation efforts.
• Provide technical guidance, mentoring, knowledge sharing, and troubleshooting assistance to other engineers.
• Participate in technical and code reviews and help establish engineering standards and best practices across the team.
• Collaborate with cloud, infrastructure, networking, cybersecurity, application development, and customer teams to resolve issues that cross technical boundaries.

This position is designed to be flexible, with responsibilities evolving to meet business needs and enable individual growth.

• Active Secret security clearance.
• Minimum of five (5) years of demonstrated hands-on experience engineering, administering, and troubleshooting Kubernetes environments. Experience should include installation, configuration, operation, upgrades, troubleshooting, and maintenance of development, staging, and/or production Kubernetes environments.
• Strong Linux systems administration and troubleshooting experience, preferably with Red Hat Enterprise Linux (RHEL).
• Demonstrated experience developing and maintaining Infrastructure as Code (IaC) using technologies such as Terraform.
• Demonstrated experience with configuration management and infrastructure automation using technologies such as Ansible.
• Strong hands-on experience designing, maintaining, and troubleshooting CI/CD pipelines.
