ABOUT THE ROLE

The Data Center Field Engineer – Controls and Building Management Systems (BMS) is a leadership role focused on the controls, automation and operational supervision aspects of data center infrastructure. This position involves overseeing the design, installation, maintenance, and troubleshooting of controls and building management systems within the data center environment. Typically, controls and BMS comprise of controlling and automation equipment (programmable logic controllers [PLC], automation cards, sensors, operational data analysis and supervision). The Field Engineer collaborates closely with cross-functional teams, provides technical expertise, and ensures the reliability and efficiency of the controls, building management and electrical power management components supporting data center operations.

The Data Center Field Engineer – Controls and BMS is responsible for conducting technical audits of data center control, monitoring, automation and actuation systems to assess their resilience, reliability, maintainability and compliance with established standards. The role performs in-depth evaluations of operational readiness, engineering practices and technical capabilities across the organization, ensuring that critical systems are effectively managed throughout their lifecycle.

In addition, the Senior Field Engineer actively drives the development of engineering competencies across Data4 by delivering structured training programs, technical workshops, knowledge-sharing sessions and hands-on mentoring. Through regular technical reviews, drills, simulations and competency assessments, the role strengthens the expertise of Engineering, Operations and Technical Services teams in controls systems architecture, troubleshooting methodologies, system optimization and best operational practices.

The position acts as a subject matter expert for Controls, BMS and EPMS technologies, fostering a culture of continuous improvement, technical excellence and standardization across all sites. By promoting consistent engineering practices, improving technical knowledge and supporting complex operational challenges, the Field Engineer ensures that teams are equipped to maintain the highest standards of safety, reliability, efficiency and resilience within mission-critical data center environments
