and associated cloud services supporting HME's mining solutions.

• Implement and enforce IT security protocols aligned with best practices for
  
  

industrial and cloud-based systems.

• Conduct routine system audits, software updates, performance tuning, and
  
  

vulnerability assessments.

• Support business continuity and disaster recovery planning, including
  
  

automated backup and restoration procedures.

• Collaborate closely with development, operations, and engineering teams to
  
  

support software deployments, integration with field hardware, and data

element systems.

• Implement and manage identity and access management (IAM) frameworks
  
  

across cloud and enterprise systems.

• Manage version control, code repositories, and CI/CD automation pipelines in
  
  

collaboration with development teams (e.g., GitLab, GitHub Actions).

• Provide Tier 2/3 support for infrastructure-related escalations across
  
  

international time zones.

• Maintain asset inventories, license tracking, and compliance logs.
• Coordinate and support third-party IT and security audits.
• Support cybersecurity initiatives, including endpoint protection, vulnerability
  
  

scanning, and zero-trust network configurations.

• Participate in cross-team planning for infrastructure scale-up in new regions or
  
  

Mining Deployments. Required Skills & Qualifications

• Minimum of 10 years experience in IT systems administration or infrastructure
  
  

roles, preferably in industrial or technology-driven environments.

• Proven expertise in Linux server administration (Red Hat, CentOS, Ubuntu).
• Strong working knowledge of Docker, container orchestration, and CI/CD
  
  

pipelines.

• Experience managing virtual environments and enterprise-grade Office 365
  
  

environments.

hardening.

• Demonstrated hands-on experience with AWS services and cloud architecture.
• Ability to script and automate tasks using Bash, PowerShell, or Python.
• Excellent troubleshooting, documentation, and communication skills.
• Strong understanding of zero-downtime deployment, fault tolerance, and
  
  

load balancing strategies.

• Experience with infrastructure-as-code tools like Terraform or Ansible.
• Familiarity with monitoring and observability tools (e.g., Prometheus, Grafana,
  
  

Zabbix).

• Proven ability to work across hybrid networks (LAN/WAN/cloud + field/edge
  
  

hardware environments).

Preferred Experience

• Background in mining, construction, industrial automation, or other field-based
  
  

industries with critical infrastructure.

• Bachelor's degree in Information Technology, Computer Science, or a related
  
  

technical discipline.

• Industry certifications such as RHCE, AWS Certified SysOps Administrator,
  
  

Microsoft 365 Certified: Enterprise Administrator Expert, or similar credentials.

• Experience in supporting infrastructure for mining operations, real-time data
  
  

platforms, or telemetry systems will be highly regarded.

• Experience in edge computing, industrial IoT, or telemetry-driven architecture.
• Working knowledge of ISO 27001, SOC 2, or NIST cybersecurity standards.
• Experience with incident response planning and security event log correlation.
• Background supporting DevOps or SRE environments is an advantage.
