Job Description

Oteemo is seeking a Senior DevOps / Platform Engineer to lead the migration of an existing portfolio of applications into a containerized environment. This is a hands-on engineering role focused on Kubernetes orchestration, Helm chart development, and ensuring applications operate reliably on a RHEL 8 / Ceph-based private cloud platform. You will work at the intersection of application development and infrastructure, translating software running in Java and C++ into well-defined, production-ready containers.

Core Responsibilities

• Design, build, and maintain Kubernetes deployments and Helm charts for migrating existing applications into containerized workloads.
• Collaborate with application developers to understand Java and C++ codebases and ensure containers accurately reflect runtime requirements.
• Deploy and manage applications on a PAAS stack built on RHEL 8 and Ceph storage running on x86/64 hardware.
• Apply OS and application hardening standards including STIG and NISPOM compliance as security requirements mature throughout the program.
• Feed migration changes and deltas back into CI/CD pipelines built on GitLab and Jenkins as needed.
• Leverage Ansible for infrastructure automation tasks to support deployment consistency.

Qualifications

• Containerization — Primary Focus
• Strong hands-on experience with Kubernetes for workload orchestration (deployment, services, config maps, persistent volumes, RBAC).
• Proficient with Helm for templating and managing Kubernetes application deployments.
• Proven track record migrating legacy or monolithic applications into containerized architectures.
• Application Language Familiarity
• Working knowledge of Java application structure, build systems (Maven/Gradle), and runtime behavior.
• Familiarity with C++ application compilation, linking, and runtime dependencies as they relate to containerization.

Platform — PAAS / Infrastructure

• Experience with Red Hat Enterprise Linux 8 administration and configuration.
• Familiarity with Ceph distributed storage and its integration in private cloud environments.
• Comfort working on x86/64 infrastructure in an on-premises or air-gapped environment.

Security & Compliance

• Understanding of STIG (Security Technical Implementation Guide) standards and their application to OS and container images.
• Awareness of NISPOM requirements in a defense or government contracting context.
• Experience with OS hardening, image hardening, and CIS benchmark application.

Preferred Qualifications

• GitLab CI/CD pipeline configuration and management.
• Jenkins pipeline development and maintenance.
• Ansible playbook authoring for infrastructure automation and configuration management.
• Experience with PAAS infrastructure buildout on RHEL 8 and Ceph.
