[Hiring] DevSecOps Engineer @Core4ce Careers

Role Description

Core4ce is hiring a Senior DevSecOps Engineer to support a large, secure Department of War (DoW) 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 DevSecOps technologies that support them.

The ideal candidate will have deep, demonstrated Kubernetes experience, preferably including Red Hat OpenShift, 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 DevSecOps platform work together and will be capable of troubleshooting complex problems across:

• Kubernetes
• Linux
• Cloud infrastructure
• Networking
• Security
• Identity
• CI/CD pipelines
• 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 DevSecOps 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.

Qualifications

• Active Secret security clearance.
• Minimum of five (5) years of demonstrated hands-on experience engineering, administering, and troubleshooting 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.
• Experience with Git-based development workflows and platforms such as GitLab.
• Strong understanding of containers, container images, container registries, and container lifecycle management.
• Strong understanding of Kubernetes concepts including networking, ingress, DNS, storage, RBAC, certificates, secrets, resource management, workload scheduling, deployments, services, and cluster operations.
• Demonstrated ability to troubleshoot complex technical issues across multiple layers of infrastructure and software.
• Experience with cloud infrastructure and services, preferably Amazon Web Services (AWS).
• Experience implementing or supporting security controls and automated security testing within DevSecOps environments.
• Demonstrated experience working directly with customers or application teams to gather requirements, troubleshoot issues, and develop technical solutions.
• Strong written and verbal communication skills with the ability to communicate complex technical issues to both technical and non-technical audiences.
• Demonstrated ability to mentor engineers and provide technical guidance to other team members.

Requirements

• Significant hands-on engineering and administration experience with Red Hat OpenShift.
• Experience migrating Kubernetes platforms and application workloads to Red Hat OpenShift.
• Experience with Rancher and RKE2 Kubernetes environments.
• Experience operating Kubernetes/OpenShift workloads within AWS, including AWS GovCloud.
• Experience with GitLab Ultimate and enterprise CI/CD environments.
• Experience with container and DevSecOps technologies such as Harbor, Trivy, Red Hat Advanced Cluster Security (RHACS), HashiCorp Vault, and Artifactory.
• Experience implementing or supporting SBOMs, preferably using CycloneDX, and software supply-chain security practices.
• Experience with observability and monitoring technologies such as Prometheus, Grafana, Splunk, and OpenTelemetry.
• Experience with identity and access management technologies such as Keycloak.
• Experience with container registries, artifact repositories, vulnerability scanning, image promotion, and secure software delivery practices.
• Experience with Ansible Automation Platform (AAP).
• Familiarity with Zero Trust principles and their application to cloud-native applications and workloads.
• Experience working within a DoD, federal government, healthcare, or other highly regulated environment.
• Experience navigating DoD cybersecurity, network, access, authorization, and accreditation requirements.
• Experience supporting platform modernization or large-scale Kubernetes/OpenShift migration initiatives.
• Experience working in a DevOps or DevSecOps environment using Agile methodologies.

Benefits

• 401(k) with 100% company match on the first 6% deferred, with immediate vesting.
• Comprehensive medical, dental, and vision coverage—employee portion paid 100% by Core4ce.
• Unlimited access to training and certifications, with no pre-set cap on eligible professional development.
• Tuition assistance for job-related degrees and courses.
• Paid parental leave, PTO that grows with tenure, and generous holiday schedules.
• Opportunity to propose bold innovations through The Forge with internal backing.
