SCADA Platform & OT Network Administration

• Administer a multi-gateway Ignition SCADA environment, including redundant CMS/FMS production gateway pairs, an admin gateway, and development gateways
• Lead version upgrade planning and execution across the gateway fleet, including Enterprise Administration Module (EAM) Controller/Agent topology and Remote Tag Provider architecture for dev-to-production tag consumption
• Design and maintain Perspective-based HMI screens and support Python/Jython scripting for automated reporting, alarming, and notification workflows
• Diagnosing and resolving OT network issues affecting control communications
• Maintain OPC UA server/client architecture and certificate management between PLCs and the SCADA layer

PLC Programming & Controls Development

• Develop, test, and maintain control logic on Schneider Electric M251 and M580 platforms (EcoStruxure Machine Expert) for HVAC air handling/makeup air units, process utilities, and life-safety monitoring points
• Author control narratives and functional logic for system, including but not limited to HVAC, Process cooling water, Waste Water, etc..
• Configure and commission variable frequency drives and other motor equipment.
• Develop and maintain a site PLC hardware standard governing controller selection criterion for redundant vs. non-redundant systems
• Write and maintain Modbus TCP, OPC UA, and Ethernet/IP integration logic between PLCs, VFDs, and third-party devices

Commissioning & Project Execution

• Lead startup and commissioning of cleanroom equipment under accelerated or constrained schedules
• Coordinate commissioning activities across mechanical, electrical, and controls trade contractors to maintain project schedule and resolve field conflicts
• Review and provide technical feedback on engineering-of-record design packages, identifying discrepancies in control narratives, alarm tables, and sequence logic prior to construction
• Generate and maintain commissioning documentation, including startup checklists and test result records

Documentation, Standards & Cross-Functional Coordination

• Author and maintain engineering specifications, control narratives, and standards documents for facility automation systems
• Serve as the controls point of contact for systems integrators, engineering-of-record firms, and equipment vendors throughout design review, procurement, and field installation
• Draft scope, change order, and technical correspondence to clarify design intent and resolve gaps between issued engineering packages and field conditions
• Support vendor and contractor coordination for SCADA integration scopes spanning hundreds of field devices and thousands of monitored data points

 

Qualifications

• Bachelor's degree in Mechanical, Electrical, or Controls Engineering, or equivalent practical experience
• Hands-on PLC programming experience (Schneider Electric M251/M580 or comparable platforms such as Allen-Bradley, Siemens) using IEC 61131-3 languages (Structured Text, Ladder Logic)
• Production experience with an industrial SCADA platform (Inductive Automation Ignition preferred) including Perspective/Vision HMI development and gateway administration
• Working knowledge of industrial communication protocols: Modbus TCP, OPC UA, Ethernet/IP
• Understanding of OT network architecture, including VLAN segmentation, managed switch configuration
• Experience with control sequences and building/facility automation systems
• Strong written communication skills for technical documentation and cross-team coordination with engineering, construction, and vendor partners

Preferred Qualifications

• Experience supporting a semiconductor fab, cleanroom, or other critical-infrastructure facility (life-safety monitoring, ultra-pure water, process cooling water systems)
• Familiarity with VFD configuration and commissioning (Danfoss, ABB, Allen Bradley or comparable)
• Experience with Ignition Enterprise Administration Module (EAM) and multi-gateway redundant architectures
• Exposure to building management system migrations (e.g., legacy BMS platforms to modern SCADA)
• Scripting experience in Python/Jython for SCADA automation and reporting

Additional Information

• This role will work on site in Roseville, CA.
• This position generally works Monday-Friday, additional hours as necessary 
• Indefinite US work authorized individuals only. Future sponsorship for work authorization unavailable.
