Systems Administrator

American Chemet Corporation • East Helena, MT

29d • Onsite

About The Position

SUMMARY
Manage the distributed control system (DCS) platform and evolve the company's multi-site network infrastructure. This position combines classic network administration with forward-looking IT competencies like hybrid/multi-cloud connectivity, AI-assisted monitoring, secure access service edge (SASE) principles, zero trust network access (ZTNA), and operational technology (OT) considerations.

ESSENTIAL DUTIES AND RESPONSIBILITIES
The essential duties and responsibilities related to this position include, but are not limited to, the following:
Administer and support hybrid cloud environments (e.g., Azure AD Connect, AWS hybrid connectivity) to enable secure data flow between on-premises systems and cloud services.
Diagnose, maintain and configure complex DCS systems and networks.
Perform regular patch management and firmware updates on industrial hardware and software, coordinating with operations to minimize production downtime.
Monitor and respond to cybersecurity threats targeting industrial control systems, including anomaly detection in process control networks.
Develop, test, and maintain OT-specific incident response and recovery plans to minimize impact on plant operations during security events or system failures.
Plan, coordinate, and implement advanced network security measures, including firewalls, intrusion detection/prevention systems, and multi-factor authentication, to protect data, software, and hardware.
Design, configure, and test computer hardware, networking software and operating system software.
Recommend changes to improve systems and network configurations and determine hardware or software requirements related to such changes.

Requirements

• Extensive knowledge of principles, practices, and procedures for designing, analyzing, securing, and maintaining complex network systems, including servers, workstations, virtualization environments (e.g., VMware, Hyper-V), hybrid cloud integrations, and industrial control systems (DCS, SCADA, PLCs).
• In-depth experience with modern operating systems (Windows Server, Linux), networking protocols, firewalls, intrusion detection/prevention systems, and secure configuration management in both IT and OT environments.
• Proficiency in cybersecurity best practices for operational technology (OT), including familiarity with standards such as IEC 62443, NIST 800-82, network segmentation (Purdue Model), vulnerability assessment, patch management, and threat monitoring in industrial settings.
• Strong working knowledge of automation and scripting tools (e.g., PowerShell, Python, Bash) to streamline administrative tasks, configuration management (e.g., Ansible), and monitoring solutions.
• Experience with cloud and hybrid environments (e.g., Azure AD, AWS hybrid connectivity) to support secure data integration between on-premises OT systems and enterprise/cloud services.
• Advanced analytical and problem-solving skills to anticipate future technologies, assess user and operational needs, evaluate automation feasibility, provide expert technical consultation, and resolve complex issues rapidly while minimizing impact on plant/production uptime.
• Excellent communication skills (oral and written) to interact effectively with diverse stakeholders, including technical teams, non-technical plant operations staff, management, vendors, and end-users; proven ability to build and maintain collaborative relationships.
• Ability to thrive in high-stakes environments requiring quick decision-making, multitasking, and adherence to safety, compliance, and availability priorities in industrial control systems.
• Bachelor’s degree in Computer Science, Information Technology, Engineering, Cybersecurity, or a related field (or equivalent combination of education and experience); advanced certifications such as CompTIA Security+, Microsoft Certified: Azure Administrator Associate, CISSP, GICSP (Global Industrial Cyber Security Professional), or relevant OT/ICS security credentials highly preferred.
