They are seeking a Principal Operations Engineer, Controls to serve as the senior technical authority for operational building automation and control systems across their AI data center portfolio, ensuring efficient and effective operations. Responsibilities • Serve as the principal operational technical authority for BMS, EPMS, PLC, and equipment-level control systems across the fleet • Own all material BMS changes and enhancements across the fleet as part of a coordinated global controls posture; ensure standardization where it matters and discipline around change control everywhere it matters • Lead technical and operational site audits across active and pre-activation sites focused on sequences of operation, alarming, trending, integration health, and cybersecurity hygiene; produce operational health assessments with prioritized findings and own the remediation roadmap through closure • Own controls operational readiness for new sites coming online — assess team capability, validate sequences, and personally sign off on operational handover from commissioning to steady-state operations • Review operational designs for controls scope on new builds and retrofits — including sequences of operation, points lists, and network architecture — and represent the operational point of view in design forums • Feed structured operational learnings back into the design and manufacturing organization as we shift toward repeatable, productized data center builds; reinforce patterns that work and drive out patterns that have not held up in operations • Diagnose and direct repair of complex control system malfunctions across multiple platforms and protocols; lead PID tuning and trend analysis on systems that are not performing • Author and approve high-risk MOPs, EOPs, and AOPs for controls work; serve as the final technical approver for high-consequence controls changes across the fleet • Lead root cause analysis for significant controls-driven events; drive corrective actions through to closure and ensure learnings propagate across all sites • Partner with QA/QC during construction to provide an operational perspective on integrator programming, point-to-point verification, and controls installation quality • Build and deliver technical training to Field Engineers and operational teams; own the technical curriculum for controls content in the campus rotation and training model • Mentor Field Engineers and rising operational leaders; act as the senior technical voice in operational reviews, incident reviews, and design reviews Skills • 10+ years of hands-on experience in building automation, industrial controls, or instrumentation, with at least 5 years as the senior technical voice on a site, campus, or fleet • Data center operations experience strongly preferred; central plant, semiconductor, pharmaceutical, or other complex industrial controls experience considered • Deep, platform-agnostic command of modern BMS/BAS environments (for example, Ignition, Niagara, Metasys, or EcoStruxure) and the ability to operate, troubleshoot, and standardize across them — earned in the field, not from a textbook • Fluency across the major control system communication protocols (BACnet, Modbus, SNMP, and equivalents) • PLC programming experience on at least one major platform (for example, Allen-Bradley or Siemens) • Strong working knowledge of the mechanical, electrical, and fire and life safety systems that controls coordinate • Demonstrated ability to author, approve, and execute high-risk controls MOPs and change records in live critical environments • A track record of leading root cause analysis on significant controls-driven events and driving corrective actions to closure • A track record of holding integrators, OEMs, and service vendors accountable — you know how to enforce a programming and documentation standard without burning the relationship • Strong written communication: operational health assessments, sequences, RCAs, procedure reviews, and design review feedback are second nature • Comfort operating as the senior technical voice across operations, design, construction, hardware, and EHS • Willingness to travel extensively across the fleet • Associate's or Bachelor's degree in Electrical Engineering Technology, Controls Engineering, Building Automation, or related field • Hyperscale or large colocation operational experience at hundreds of MW+ scale • Experience with EPMS platforms (for example, Schneider Power Monitoring Expert or Eaton Power Xpert) and DCIM tooling • Experience with historian platforms (for example, OSIsoft PI or Ignition Historian) and scripting against controls data (Python, SQL) • Certification on a leading BMS/BAS platform (for example, Ignition) • Networking/IT certification or working knowledge of OT network segmentation and cybersecurity practices • Uptime Institute AOS or equivalent operations credential • Experience operating across multiple sites or as part of a global fleet controls function • Experience contributing operational requirements into reference designs or productized data center builds Benefits • Competitive total compensation package (salary + equity). • Retirement or pension plan, in line with local norms. • Health, dental, and vision insurance. • Generous PTO policy, in line with local norms. • Total compensation may also include equity in the form of stock options.
