Principal Mechanical Engineer-Energy Systems

Microsoft’s Cloud Operations & Innovation (CO+I) is the engine that powers our cloud services. The CO+I CTO Office’s Energy Technology team is looking for a Principal Mechanical Engineer- Energy Systems focused on energy systems to provide technical leadership for capabilities that enable Microsoft datacenters to serve our customers. This role will shape how energy technology requirements are defined, evaluated, and deployed across Microsoft’s global portfolio, partnering closely with datacenter engineering, electrical infrastructure, policy, operations, and external technology partners. As a Principal Mechanical Engineer on the Energy Technology team, this individual will drive Microsoft’s technical approach to energy systems technologies. The role requires deep energy systems expertise, strong technical judgment, and the ability to influence engineering, commercial, and policy stakeholders around scalable solutions that improve reliability, grid compatibility, and operational continuity. The successful candidate will be a subject matter expert in energy systems with experience in energy systems infrastructure design. The candidate will also understand the interactions between the grid and datacenter energy systems and will lead the development of architectures, requirements, and deployment pathways that enable resilient operation. In alignment with Microsoft values, we are committed to cultivating an inclusive work environment for all employees and positively impacting our culture every day.
