  • Develop, review, and maintain up to date the maintenance philosophy beyond e.g. preventative maintenance strategy (pre and post warranty scope, maintenance intervals), OEM alignment, and spares philosophy/critical spares.
  • Assist sites as the technical interface with OEMs and vendors for chronic issues, design defects, firmware issues/updates, sequence changes, etc.
  • Review, develop (as needed), and deliver mechanical technical training to reduce reliance on external training providers and build capability within site teams.
  • Coordinate with overall operational engineering team and Critical Environment Management (CEM) team to maintain a knowledge base of standard fixes, known failure modes, lessons learned, technical bulletins, and overall data center mechanical knowledge.
  • Attending required meetings with key stakeholders to represent Operations in technical discussions.
