EPMS​/SCADA Integration Engineer

Hiring Senior Engineer – Sacramento, CA (Hybrid) – Role Code: ZA-31012

This role supports our EPMS/SCADA and end‑to‑end service scopes.

Protection relays and controllers generate data — status, alarms, metering, SOE — that has to reach operators through HMI/SCADA and reach historians for trending and analysis. This role exists because EPMS/SCADA integration bridges the gap between the protection layer and the monitoring layer, spanning multiple protocols (DNP3, Modbus TCP/RTU, BACnet/IP, SNMP) and HMI platforms (Factory Talk, Wonderware, Ignition). You own the monitoring and control layer: point lists, HMI screen development, alarm rationalization, historian integration, and the BMS‑to‑power system boundary.

When an operator sees a trip alarm or a historian trends power quality, your integration made that data path work.

• EPMS/SCADA architecture design: data concentrator topology, protocol gateways, redundancy schemes
• HMI/SCADA development on Factory Talk View, Wonderware, or Ignition platforms — operator graphics, navigation, alarm annunciation
• Point list engineering: RTAC‑to‑HMI point maps, Modbus/DNP3 register assignments, SOE tagging schemas
• Alarm rationalization: alarm matrices, priority assignments, flood prevention, operator notification logic
• Historian integration: meter‑to‑historian tag configurations, data collection automation, trending/reporting templates
• BMS‑to‑power system integration boundary: BACnet/IP segmentation, BBMD broadcast management, cross‑system monitoring
• Platform refresh/upgrade:
  Factory Talk View server/client upgrades, cutover procedures maintaining operational continuity

• Wonderware InTouch / System Platform
• Ignition
• Factory Talk View Studio
• ALC WebCTRL
• AcSELerator
• RTAC

• SEL
• Electro Industries (EIG)

• DNP3
• Modbus TCP
• Modbus RTU
• BACnet/IP
• BACnet MS/TP
• SNMP

• Reviewed existing SCADA/HMI configuration on an active project — point lists, alarm setup, operator graphics
• Developed or modified HMI screens for an integration scope (Factory Talk View, Wonderware, or Ignition)
• Produced a point list or alarm matrix for an RTAC‑to‑HMI data path

• Owning EPMS/SCADA integration scope on at least one project — architecture through functional testing
• Historian integration delivered: meter data flowing through RTACs to dual historian servers with SOE tagging
• Alarm rationalization completed and validated through alarm flood testing

• 7+ years SCADA/HMI or EPMS integration for critical power or industrial control systems
• HMI development on at least one major platform:
  Factory Talk View, Wonderware InTouch/System Platform, or Ignition
• Multi‑protocol integration: DNP3, Modbus TCP/RTU, and at least one of BACnet/IP or SNMP
• Point list engineering: protocol‑to‑HMI data mapping, SOE tagging, alarm configuration
• Alarm rationalization experience: alarm matrices, priority tiers, flood prevention strategies
• Understanding of power system SCADA architecture: data concentrators, protocol gateways, redundancy

• SEL RTAC‑3530 as SCADA data concentrator / protocol gateway
• BMS/BACnet integration experience (ALC WebCTRL or equivalent)
• Power quality metering integration (EIG Shark‑250 or equivalent)
• Historian platform experience (OSIsoft PI, Wonderware Historian, or Factory Talk Historian)
• IT/OT boundary management: network segmentation between BMS and power system OT networks

• Travel 20–40% for site integration, functional testing, and cutover support
• Site hours: standard office hours for development; site hours during integration testing and SCADA cutover windows
• Customer‑Facing Interface with prime contractor controls engineers, BMS integrators, and facility operations for HMI requirements and alarm philosophy
• Documentation Heavy — point lists, alarm matrices, HMI screen specifications, historian tag configurations, integration test procedures
• Field Safety Minimal direct electrical exposure; NFPA 70E awareness for switch gear‑adjacent controls equipment

• Full‑stack integration: from relay terminals through RTACs through HMI to historian…
