• Design and construct platform infrastructure spanning build, test, deployment, and release workflows across software and hardware environments • Periodic on-call shifts during business hours focused on incident response and operational support for team-owned services • Provide support and troubleshooting to internal customers • Maintain and evolve an internal, multimodal test execution platform across target hardware and simulation, with integration into requirements tracking systems • Develop and operate shared platform services, including workflow orchestration, observability, remote development environments, and authentication infrastructure • Drive engineering quality through reference implementations, best practices, and continuous improvement of platform reliability and scalability • Mentor engineers and elevate technical standards across design, implementation, and operations

• Own and evolve our AWS infrastructure using Terraform and Pulumi Cloud - treating infrastructure as a product that engineering teams depend on. • Design and maintain internal developer tooling and libraries that standardize how we build and ship - code generation, shared SDKs, data access patterns, and service scaffolding. • Create and maintain golden paths for common workflows (new service setup, background jobs, event streams, APIs) so teams can ship quickly with built-in security and observability (and consistent defaults across services). • Build and maintain CI/CD pipelines and per-PR ephemeral environments that make deploying feel easy and safe. • Drive reliability through SLOs, auto-scaling, incident response, and postmortems - and build systems that make the next incident less likely. • Create observability tooling and shared instrumentation libraries that give engineers real-time insight into their services. • Enforce security best practices across IAM, secrets management, encryption, audit logging, and DDoS protection. • Own the reliability and performance of our data platform (Aurora PostgreSQL) - provisioning, backups, failover, and tuning - and build tooling that makes safe usage the default. • Reduce toil through automation and self-service tooling so engineers can move fast without waiting on the platform. • Contribute to architecture decisions and documentation, and participate in on-call rotation (shared by the whole engineering team).

• Design and build developer-focused tools and services that improve the software development lifecycle. • Implement AI-driven capabilities across engineering workflows, including code assistance, documentation generation, test automation, and code review support. • Improve the developer experience by identifying friction points and streamlining workflows. • Promote best practices for developer tooling and local development environments. • Design, deploy, and maintain the core AI platform infrastructure for production grade AI agents. • Participate in design and architecture discussions and contribute technical guidance. • Collaborate closely with engineers and cross-functional partners to deliver reliable systems. • Mentor other engineers through code reviews and design feedback.

Core4ce is seeking a mid-level DevSecOps Engineer with Red Hat OpenShift experience, specifically focused on OpenShift Virtualization (OpenShift Virt), to support the evolution of our enterprise platform services. This role will enable the transition of workloads from traditional virtualization platforms (VMware vSphere) into OpenShift-based virtualized environments, maintaining VM-based workloads while modernizing platform operations. This position is not focused solely on containerization. Instead, the engineer will play a key role in migrating and operating virtual machines within OpenShift Virtualization, ensuring continuity of existing workloads while enabling a path toward modernization where appropriate. The selected candidate will work across infrastructure and platform teams to deliver a secure, automated, and scalable platform, aligned to DevSecOps and Zero Trust principles within a Defense Health Agency (DHA) environment. Responsibilities: - Support the design, deployment, and sustainment of Red Hat OpenShift clusters, with a focus on OpenShift Virtualization (KubeVirt) capabilities - Collaborate with platform teams to migrate virtual machines from VMware vSphere into OpenShift Virtualization environments - Implement and manage VM lifecycle operations within OpenShift, including provisioning, scaling, patching, and backup integration - Develop and maintain CI/CD pipelines supporting both VM-based and container-based workloads where applicable - Automate platform and infrastructure processes using Infrastructure as Code (IaC) tools (e.g., Ansible, Terraform) - Integrate security controls into platform pipelines and VM/image management processes (e.g., image hardening, vulnerability scanning) - Support platform observability and monitoring, including integration with enterprise tools (e.g., Prometheus, Grafana, Splunk) - Ensure compliance with DoD RMF, DISA STIGs, and Zero Trust architecture requirements - Troubleshoot issues across virtualized workloads, OpenShift platform services, and supporting infrastructure - Collaborate within a Scaled Agile (SAFe) framework, supporting PI planning and iterative delivery *This position is designed to be flexible, with responsibilities evolving to meet business needs and enable individual growth. Required Qualifications: - 3–6 years of experience in DevOps/DevSecOps, platform engineering, or infrastructure engineering - Active Secret clearance (or ability to obtain) - DoD 8570/8140 IAT Level II certification (e.g., Security+ CE) required or ability to obtain within 3 months - At least one related industry certification or the ability to obtain within 12 months, such as Microsoft Certified Azure Administrator, AWS Cloud Practitioner, or Certified Kubernetes Administrator (CKA) - Hands-on experience with Red Hat OpenShift, including OpenShift Virtualization (OpenShift Virt / KubeVirt) - Demonstrated experience supporting or administering VMware vSphere environments - Experience with VM migration strategies and tooling, particularly migrations into OpenShift Virtualization - Proficiency with CI/CD tools (e.g., GitLab CI, Jenkins) - Experience with Infrastructure as Code (Ansible, Terraform, or similar) - Strong Linux system administration skills (RHEL preferred) - Experience implementing security practices within DevSecOps pipelines and VM environments - Strong troubleshooting and problem-solving skills Preferred Qualifications: - Experience within DoD, DHA, or federal government environments - Familiarity with KubeVirt architecture and VM orchestration within Kubernetes - Experience with hybrid VM/container platform operations within OpenShift - Knowledge of VM migration tooling (e.g., migration kits for virtualization, image conversion, data replication approaches) - Experience integrating with enterprise identity solutions (e.g., Keycloak, Entra ID, mJAD) - Exposure to observability tools (Prometheus, Grafana, Splunk) - Understanding of SAFe Agile practices and DevSecOps pipelines in regulated environments Why Work for Us?
