• Strong criticalthinking and problemsolving skills, with the ability to analyze complex system interactions, perform root cause analysis, and implement effective corrective actions in highavailability terminal and pipeline environments.

• Strong working knowledge of Windows operating systems and Linux environments, including installation, configuration, patching, and troubleshooting in OT environments.

• Strong understanding of how OT devices communicate over segmented networks, including industrial protocols, required ports, and system dependencies. Experience reIP ing OT devices (PLCs, HMIs, OIPs, gateways, servers) and validating devicetodevice communications.
  (Handson firewall or switch configuration is not required.)

• Experience configuring or overseeing HMI screen development using standardized style guides and templates, ensuring consistency, usability, and alignment with operational best practices.

• Experience supporting PLC, HMI, and OIP password protection initiatives, including implementation and validation of access controls.

• IT/OT Application Experience: Hands-on experience supporting and administering IT/OT applications such as  FactoryTalk AssetCentre, Rockwell Secure OT, BeyondTrust Privileged Remote Access (PRA), Pleasant Password Server, or similar asset management, cybersecurity, privileged access, and backup/recovery solutions.

• Security, Access, and Remote Support Capabilities: Proven ability to configure, manage, and troubleshoot secure remote access, privileged credential management, and recovery operations across IT and OT environments. This includes leveraging tools such as BeyondTrust PRA to ensure secure vendor and internal access, maintaining compliance, and supporting high-availability operational systems.

• Ability to travel up to 25% both domestically and internationally.

  
Certificates & Licenses:

• Ignition (Core or Gold Certification)

• FactoryTalk View Certification

• 7-10 years of experience supporting Terminal Automation Systems (Toptech TMS) and/or Operational Technology (OT) environments within refined fuels or related industrial domains.

• Preferred technical experience includes: Linux administration, PuTTY, Toptech TMS, MySQL, Microsoft SQL Server, Programmable Logic Controllers (PLCs), HumanMachine Interfaces (HMIs), Operator Interface Panels (OIPs), refined petroleum load rack controllers (MultiLoad, AccuLoad), client/server architectures, Penguin (Stratus) ztC Edge technologies, and browserbased applications.

• Demonstrated ability to troubleshoot, configure, install, upgrade, and support industryspecific applications and systems, including Toptech TMS, FuelsManager, Rosemount TankMaster, System Associates Inc. WeighMaster, Railman, and Digi PortServer devices. This includes diagnosing communication, data integrity, and integration issues across OT and IT boundaries.

• Strong criticalthinking and problemsolving skills, with the ability to analyze complex system interactions, perform root cause analysis, and implement effective corrective actions in highavailability terminal environments.
