Sr. Electrical Engineer, Energy Storage, AWS Global Energy

Are you passionate about the future of energy storage at scale? Do you love to innovate and apply your knowledge to advance world‑class power systems? We are seeking an experienced Electrical Engineer with extensive experience in energy storage system design, including Battery Energy Storage Systems (BESS), to support our growing requirements for novel solutions to deliver power to AWS data centers.

• Develop designs and analysis of different energy storage technologies, including battery energy storage systems, long‑duration energy storage systems, and utility‑scale energy storage.
• Support the integration of energy storage systems with various power sources—electric utilities, diesel generators, reciprocating engines, gas turbines, fuel cells, microgrids, distributed energy resources, and renewable energy—to serve data center loads in grid‑connected or grid‑independent configurations.
• Develop controls integration strategies and designs, sequence of operations, and protection and relay schemes for energy storage systems.
• Create acceptance criteria, test procedures, performance requirements, supplier requirements, and integration designs for energy storage systems, components, and products.
• Interpret and develop single‑line drawings (SLD), engineering drawings, equipment submittals, specifications, and performance data to advance concepts and solutions.
• Provide feedback to design engineering teams for design revisions for new data centers and to field engineering for operational upgrades.
• Manage concurrent projects in multiple geographical regions.
• Lead within the group and collaborate with cross‑functional teams to make critical design decisions, evaluate trade‑offs, and manage technical risks across complex power systems.
• Travel domestically and internationally may be required.

The Power Generation Solutions team creates and delivers product and engineering solutions for power and energy to help advance AWS’s mission to deliver world‑leading cloud services. The team provides technical input to realize a shared vision and strategy with partner teams and supports engineering across the project or product lifecycle.

• Bachelor’s degree in Engineering or a related field.
• 6+ years of experience leading energy storage designs for utility‑scale or complex mission‑critical facilities, plus 4+ years of design or operational support for energy storage systems.
• In‑depth knowledge of continuous operating redundant electrical systems and power infrastructure, including (but not limited to) UPS, medium and low voltage switch gear, power distribution units, variable frequency drives, and transfer switches.
• Experience with inverter controls, EMS, and closed‑loop control optimization.
• Experience with medium‑ and high‑voltage equipment, substation configurations, protection requirements, and integration of energy storage systems.
• Ability to interpret wiring diagrams, single and three‑line diagrams, submittals, and electrical drawing packages.

• Master’s degree in Electrical Engineering.
• Licensed Professional Engineer.
• 10+ years of direct experience with the design, construction, operation, or maintenance of mission‑critical data centers or power infrastructure.
• Familiarity with power flow studies, substation design, protection coordination, and utility interconnection requirements.
• Experience with diesel generators, distributed energy resources, gas turbines, and renewable energy.
• Experience with data analysis to identify availability and performance risks in power infrastructure.
• Ability to produce analyses that ensure data centers satisfy design requirements, including availability goals and power quality specifications.
• Experience with fast‑track design/build projects and multiple significant upgrade projects.
• Experience with commissioning and/or performance testing of critical infrastructure and associated control systems.
• Experience with scripting languages (e.g., Python, R) or statistical/mathematical software (e.g., R, SAS, MATLAB).
• Excellent attention to detail and communication skills.
