Role Summary

The OT Systems Engineer is responsible for deploying, configuring, and supporting operational technology (OT) networks for utility-scale Battery Energy Storage System (BESS) projects. This role is critical to successful commissioning and system handover, ensuring reliable communications between control systems, EMS, PCS, BMS, SCADA, and remote monitoring platforms.

This is a field-facing, deployment-oriented role focused on bringing new projects online.

Key Responsibilities

  • Deploy and configure OT network infrastructure for BESS projects, including switches, routers, firewalls, cellular devices, and site communications equipment
  • Support commissioning activities by ensuring reliable connectivity between EMS, PCS, BMS, protection relays, meters, and SCADA systems
  • Configure network segmentation, VLANs, routing, and secure remote access appropriate for OT environments
  • Troubleshoot network and communication issues during commissioning and early operations
  • Work closely with Deployment Engineers, Controls Engineers, EMS teams, and Field Commissioning teams to resolve system integration issues
  • Support site bring-up, factory acceptance testing (FAT), site acceptance testing (SAT), and handover to service teams
  • Document site network architectures, configurations, and as-built drawings
  • Contribute to the development of standardized network designs, templates, and deployment procedures
  • Support remote monitoring, data acquisition, and secure connectivity to central monitoring platforms
  • Travel to project sites as required during deployment and commissioning phases

Required Experience & Skills

  • Experience deploying OT or industrial networks in the field (power, renewables, utilities, manufacturing, oil & gas, or similar)
  • Strong understanding of TCP/IP networking fundamentals in operational environments
  • Hands-on experience with industrial networking equipment (switches, routers, firewalls)
  • Familiarity with SCADA, PLCs, HMIs, EMS, or industrial control systems
  • Ability to troubleshoot across network, software, and controls boundaries
  • Comfortable working in commissioning environments with incomplete information and time pressure
  • Willingness to travel to project sites during deployment phases

Preferred Experience

  • Experience with utility-scale BESS, solar, wind, or substation environments
  • Experience with cellular networking, VPNs, and secure remote access for OT systems
  • Familiarity with IEC 61850, Modbus, DNP3, or similar protocols (high-level understanding)
  • Experience supporting commissioning teams in the field
  • Background bridging IT networking concepts into OT environments

What Success Looks Like (6–12 Months)

  • New BESS sites are brought online with stable, secure network connectivity
  • Commissioning timelines are supported, not delayed, by network readiness
  • Network issues are resolved quickly and collaboratively during deployment
  • Site documentation and standards improve over time
  • Field and commissioning teams trust this role as a reliable partner

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
