Senior Platform Engineer (RedHat and Kubernetes)

As a Senior Platform Engineer, you are a primary technical contributor responsible for building the services, tools, and processes that enable our engineering organization. We are looking for a "builder" who thrives in bare-metal and virtualized on-premise environments. You will lead complex technical projects, mentor junior engineers, and ensure our on-premise stack is automated, secure, and highly available.

The On-premise Infrastructure Engineering team is responsible for:

• Design and implementation of local CI/CD pipelines within dedicated on-premise environments.

• Development and operation of common platform services—centered on RedHat OpenShift and Kubernetes.

• Full-stack ownership: Managing the physical and virtual layers, including Networking, Storage, and Compute.
  
  Responsibilities will include:

  • Implementation: Lead the end-to-end deployment of RedHat OpenShift and Kubernetes clusters on private hardware.

  • Automation: Build and maintain "Infrastructure as Code" (IaC) pipelines to automate server provisioning, OS hardening, and application deployment.

  • Troubleshooting: Serve as the escalation point for complex networking, storage, or container orchestration issues.

  • Security & Compliance: Implement security best practices (CIS hardening, SELinux) for air-gapped or highly secure on-premise environments.

  • Performance Tuning: Optimize Linux kernel parameters and network configurations for high-throughput, low-latency Public Safety applications.

  • Mentorship: Provide technical guidance and conduct rigorous code/configuration reviews for the engineering team.

  Qualifications:

  • Experience: 3+ years of professional experience in Systems Engineering, Platform Engineering, or Site Reliability Engineering (SRE) with a heavy focus on on-premise environments.

  • Education: Bachelor’s degree in Computer Science, Information Technology, or a related technical field (or equivalent practical experience).

  • Infrastructure Depth: Proven track record of deploying and maintaining production-grade Kubernetes or RedHat OpenShift clusters on bare-metal or virtualized private hardware.

  • Linux Expertise: Strong command of Linux internals (storage, networking, process management) and the ability to debug issues across the entire stack.

  • Network Proficiency: Hands-on experience with Data Center Networking fundamentals, including switching/routing, load balancing, and firewall rule implementation.

  • Automation Mindset: Experience replacing manual operational tasks with automated workflows using Python, Ansible, or similar tools.

  • Critical Thinking: Ability to work in an agile environment and handle the high-pressure demands of maintaining mission-critical Public Safety systems.

  • Collaboration: Strong communication skills with the ability to document complex technical architectures and mentor junior team members.

  • Strong level of curiosity and interest to learn

  • Self motivated and able to maintain focus in a pressured environment

  Primary Skills (Must-Have)

  • Orchestration: Expert-level RedHat OpenShift (OCP) & Kubernetes.

  • Operating Systems: Advanced Linux Administration (RHEL preferred).

  • Networking: L3/L4 Networking, BGP, Load Balancing (NGINX/HAProxy).

  • Automation: Ansible, Python, and Shell scripting.

  • Version Control: Git & GitOps (ArgoCD or Flux).

  Nice-to-Have Skills

  • Storage: Software Defined Storage (Ceph, Rook, or ODF).

  • Virtualization: VMware vSphere or KVM management.

  • Observability: Prometheus, Grafana, and ELK stack.

  • Certifications: CKA (Certified Kubernetes Administrator) or RHCE.

  • Security: Experience with CIS Hardening and STIG compliance in air-gapped environments.
