STACK offers the scale and geographic reach that rapidly growing hyperscale and enterprise companies need. The world runs on data. Data runs on STACK. STACK is seeking a Technical Trainer to deliver and manage technical training programs for Critical Operators supporting a large, multi-phase data center campus. This role ensures technicians are well-prepared to operate mission-critical systems safely and effectively in a highly technical, high-reliability environment. The Technical Trainer will partner with an Instructional Designer (ID) to help ID develop curriculum and will be responsible to deliver instructor-led (classroom and virtual sessions) and hands-on training that takes learners from “zero to operational” with confidence and competence. Together, they will ensure materials are instructionally sound, technically precise, and strategically aligned with the mission of Critical Operations. The Trainer will also leverage existing internal learning paths and third-party resources, tailoring instruction to the systems and operational requirements of this campus. Many technicians will enter with limited data center experience, so the ideal candidate excels at simplifying complex topics and building technical readiness at scale. Additionally, the ideal candidate can masterfully flex between technical accuracy and flawless facilitation.
