Senior SCADA/ BMS Engineer

We are bringing our SCADA and BMS platform in house rather than farming it out. As the SCADA and BMS Engineer, you will own that platform: the Ignition environment, the screens operators actually use, the historian behind them, and the alarm and dashboard layer that tells us whether a site is healthy. You will design it, stand it up, and maintain it.

The reason this role matters: a data center is a machine, and the SCADA system is how we know whether that machine is healthy. A bad system means alarms nobody trusts, thermal events nobody saw coming, and operators flying blind at 2am. A good one means we catch problems before they become outages. Just as important, we are building sites faster than most companies build one, so the templates and standards you set on the first site are what let us go from site to site without rebuilding the stack each time.

You will work closely with the network, security, and controls teams to get data into the system, and with site operations to make sure what they see on screen is what they need. You will also be on the hook when something breaks after hours.

This role is remote with up to 20% travel. 

• Own the design and architecture of our SCADA and BMS platform across the portfolio: Ignition environment, server and gateway topology, tag structures, naming standards, and redundancy.
• Build and maintain what operations runs on: operator screens, historian, trending, alarm configuration and rationalization, dashboards, and reporting.
• Build reusable visualization and tag templates on the first site so each site after it is a deployment rather than a rebuild.
• Integrate data from mechanical and electrical systems into SCADA: chillers, CRAHs, switchgear, generators, UPS, ATS, and metering, primarily over Modbus TCP.
• Work with the network and security teams on the OT side: segmentation from IT, remote access, and getting device data to the SCADA servers reliably.
• Integrate SCADA data with DCIM and other monitoring and reporting platforms.
• Maintain systems in production: software and firmware updates, configuration control, backup and recovery, as-built documentation, and root cause analysis on system events.
• Support the testing phase at each site by validating points, alarms, and screens against what is actually installed.
• Participate in an on-call rotation for after-hours incident response, and act as the escalation point for alarms operations cannot resolve.
• Write and maintain the standards, documentation, and runbooks that let us repeat this at the next site without starting over.

• Hands-on experience building and maintaining SCADA/HMI applications in Ignition including tag structures, alarm configuration, historian, and operator screens. 
• 5+ years designing, programming, and maintaining SCADA or BMS systems in data centers, industrial facilities, utilities, or comparable mission-critical environments.
• Experience owning a SCADA system in production, not just deploying it: alarm tuning, historian management, backups, and troubleshooting live issues.
• Strong working knowledge of Modbus TCP, which is our primary protocol, plus familiarity with BACnet and at least one of SNMP, OPC UA, DNP3, or IEC-61850.
• Ability to read mechanical and electrical drawings, one-lines, points lists, and sequences of operation well enough to know what should be on a screen and what an alarm means.
• Practical understanding of data center mechanical and electrical infrastructure: cooling topologies, UPS, generators, switchgear, and redundancy concepts.
• Willingness to travel to sites regularly.
• Bachelor's degree in electrical, mechanical, controls, or computer engineering, or equivalent hands-on experience.
