CxEs review design documents, lead Factory Witness Testing (FWT), and manage third-party commissioning vendors in the performance of onsite pre-functional, functional, and integrated systems testing. They take ownership of their projects’ successes by diving deep to resolve technical issues and having a bias for action to address ever-changing schedule and coordination demands onsite. Additionally, CxEs communicate lessons learned and continuously collaborate on program improvements.

The CxE shall provide multi-discipline input into the scheduling, test script development, designing, and planning of projects. In addition, the CxE will be required to review component submittal packages, lead Factory Witness Testing (FWT), and perform system level and integrated system testing. During commissioning, the CxE will continuously audit activities to ensure compliance with environmental, quality, and safety requirements. Additionally, the individual will be responsible for comprehensive weekly reporting of the status of all ongoing projects and lessons learned to continually improve the quality of our program. This position will include coverage of multiple inflight projects and aggressive timelines.

A day in the life

On a typical project, the CxE works across AWS engineering, capacity delivery, operations, and contractor teams to coordinate site activities, prioritize tasks, and ensure each issue has a clear path to resolution. The CxE manages the project commissioning vendor whose primary scope is to identify issues, determine criticality, propose solutions, and document their findings. If project turnover is at risk, the CxE escalates to the appropriate stakeholders. Upon project completion, the CxE will communicate lessons learned to help peers on similar projects in flight and participate in initiatives that drive improvement to the commissioning program.
