Commissioning Engineer, Commissioning Engineering

As a Data Center Commissioning Engineer (CxE), you will be part of a highly creative, efficient team tasked with tackling fascinating and challenging problems building and supporting the operations of Amazon‑owned data centers. Your role involves supporting vendors, contractors, and other teams involved in the construction and commissioning of various systems such as:

• Medium and low voltage power systems and generators
• UPS
• HVAC (air handlers, exhaust fans, VFD)
• Chilled water systems
• Building management systems (BMS)
• Electrical power monitoring systems (EPMS)
• Testing and balancing
• Pumps and hydronic systems

As the Commissioning Engineer (CxE), you will provide testing and validation oversight of AWS data center electrical and mechanical infrastructure. This includes, but is not limited to, review of design documents and equipment submittals, leading Factory Witness Testing (FWT), and managing third‑party commissioning vendors in the performance of onsite pre‑functional, functional, and integrated systems testing. You will own your projects’ successes where you deep dive to resolve technical issues and have bias for action to address schedule impacts and coordination demands onsite.

You will share lessons learned leading toward team growth and program improvements.

You will get the opportunity to provide multi‑discipline input into scheduling, test‑script development, designing, and planning of projects. During commissioning, you will continuously audit Cx vendors’ activities to ensure compliance with environmental, quality, and safety requirements. Following the AWS project reporting format, you will be responsible for regular reporting of commissioning progress and metrics of the assigned project to your Regional Commissioning Manager.

You will lead several projects simultaneously to achieve key milestones and deliver data center capacity while managing project budget as approved by Finance.

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 execute functional tests, 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 communicates lessons learned to help peers on similar projects in flight and participates in initiatives that drive improvement to the commissioning program.

The AWS Data Center Commissioning Team (ACx) is a wholly independent business within the DCGS organization. This team of veteran professional electrical engineers, mechanical engineers, controls engineers, project managers, and operators provides detailed engineering and operational review and testing of equipment designs, operational functionality, and construction practices. The team focuses on rapid delivery of a quality product while maintaining full transparency and recording metrics of every defect discovered during commissioning.

• Bachelor’s degree in Mechanical or Electrical Engineering or 5 years of relevant discipline work experience
• High technical competency in either mechanical or electrical or control systems utilized in critical infrastructures, with the capability to learn and be trained in the others
• Understanding of design concepts by reviewing mechanical or electrical design documentation, including drawings, specifications, vendor submittals, and sequences of operations, and providing feedback in accordance with Amazon standards
• Experience developing but primarily reviewing commissioning documentation such as test plans, scripts, and reports developed by vendors to ensure accuracy in accordance with design requirements

• Advanced knowledge of Microsoft Office Suite – Word, Excel, Outlook required; advanced knowledge of SharePoint…
