Senior Data Center Electrical Engineer , Mechanical Products and Services

AWS Infrastructure Services owns the design, planning, delivery, and operation of all AWS global infrastructure. In other words, we’re the people who keep the cloud running. We support all AWS data centers and all of the servers, storage, networking, power, and cooling equipment that ensure our customers have continual access to the innovation they rely on. We work on the most challenging problems, with thousands of variables impacting the supply chain — and we’re looking for talented people who want to help. You’ll join a diverse team of software, hardware, and network engineers, supply chain specialists, security experts, operations managers, and other vital roles. You’ll collaborate with people across AWS to help us deliver the highest standards for safety and security while providing seemingly infinite capacity at the lowest possible cost for our customers. And you’ll experience an inclusive culture that welcomes bold ideas and empowers you to own them to completion. Are you passionate about designing and optimizing the critical systems that power some of the world's largest and most reliable infrastructure? As a Senior Data Center Infrastructure Electrical Engineer, you will serve as a technical leader responsible for the design, architecture, and continuous improvement of data center infrastructure systems. Your work will directly influence the availability and efficiency of the physical backbone that supports millions of customers worldwide. In this role, you will tackle complex, ambiguous problems across global projects, driving solutions that are inventive, scalable, and maintainable. You will collaborate with cross-functional engineering teams, influence facility strategy, and set standards for engineering excellence. Whether you are leading the design of new infrastructure systems or resolving root causes of endemic issues, your contributions will have a meaningful, long-term impact on how Amazon builds and operates its data centers. Key job responsibilities

• Support the Data Center Design Engineering, Principal Engineering, and Hardware Engineering teams to design and develop innovative concepts into new mechanical cooling products (AHUs, chiller, pump skids, ADACs) used in AWS data centers.
• Lead the electrical aspect of new product design and development for mechanical cooling equipment, including motor controls, VFDs, power distribution panels, control wiring, and instrumentation integration.
• Collaborate with other disciplines such as mechanical engineering, structural engineering, controls/automation, reliability, QA/QC, and compliance to create well-thought-out products.
• Design and specify electrical systems for rotating equipment including fans, pumps, and compressors, ensuring proper motor sizing, protection, and control schemes.
• Create designs which meet or exceed our quality requirements while delivering a return on investment.
• Work with global suppliers and manufacturers to specify appropriate electrical components, devices, and bill of materials for AHUs, skids, and ADACs.
• Ensure compliance with federal, state, and municipal requirements and building codes across different countries, including UL, CE, IEC, NEC/NFPA 70, and other applicable standards for mechanical cooling equipment.
• Prepare, review, and approve product design and drawings including electrical schematics, single-line diagrams, wiring diagrams, panel layouts, cable schedules, and bill of materials.
• Define project scope and provide technical support for information requests prior to, and during manufacturing phases.
• Work with field engineering and commissioning teams to properly set up test processes and validate installation, operation, and performance of electrical systems within mechanical cooling products.
• Develop and review control logic, interlocks, and safety circuits for AHU, skid, chillers and ADAC assemblies in coordination with controls engineers.
• Ability to work on concurrent projects in multiple geographical regions.
• Support of Operations including failure mode and root cause analysis, maintenance and troubleshooting support, and operating procedure review for electrical systems in cooling equipment.
• Be a leader within the group as well as within internal and external teams that support the data center.
• Ability and willingness to travel domestic and internationally for up to 25% of the year. A day in the life You might start your morning reviewing design documents for a new infrastructure deployment, providing feedback that strengthens the overall architecture. By midday, you could be leading a cross-team project review, aligning engineers across regions on a shared technical approach. In the afternoon, you may dive into root-cause analysis of a recurring facility issue, proposing a mechanism to prevent future occurrences. Throughout it all, you will coach teammates, share expertise, and help shape the direction of critical infrastructure at Amazon. About the team Our team is focused on ensuring that Amazon's data center infrastructure is reliable, efficient, and ready to meet the demands of tomorrow. We work at the intersection of electrical engineering, mechanical systems, and operational technology to design and maintain the physical environments that support Amazon's global services. We value collaboration, creative problem-solving, and a commitment to continuous improvement. If you are excited about working on large-scale infrastructure challenges alongside a talented group of engineers, we would love to hear from you.
