As a Systems Modeling Mechanical Engineer at AWS, you will bridge the gap between physical infrastructure and virtual simulation, focusing on optimizing data center cooling systems. You will work with a diverse team of engineers and specialists to ensure the highest standards of safety and security while delivering innovative solutions. Your role will involve creating high-fidelity models, executing simulations, and validating new mechanical products. This position offers the opportunity to contribute to cutting-edge projects in a collaborative and inclusive environment.

• Master’s degree in mechanical engineering, Thermal Engineering, or a related field.
• 6+ years of experience in data center design, construction, or operations with a strong focus on thermal modeling.
• Deep proficiency in CFD software such as Ansys Fluent, Cadence, or similar.
• Proficiency in Python, MATLAB, or C++ for data analysis and automation.
• Hands-on experience with mechanical test fixtures, sensors, and data acquisition systems (DAQ).
• Excellent communication and report-writing skills.
• Experience in designing/testing high-density or liquid cooling systems.
• Knowledge of BIM/Revit for facility layout.
• Familiarity with ASHRAE guidelines for data center thermal management.

• Build and maintain high-fidelity system models of data center mechanical systems, including cooling infrastructure and airflow environments.
• Develop and execute CFD simulations to predict thermal performance, pressure drop, airflow distribution, and failure modes.
• Automate simulation workflows and 'what-if' scenario testing using Python, MATLAB, or equivalent scripting tools.
• Lead pre-deployment validation of new mechanical products, including heat exchangers and advanced rack architectures.
• Design and execute Hardware-in-the-Loop (HIL) lab testing that replicates realistic datacenter loading scenarios.
• Define and own Design Verification Plans (DVPs) and test procedures for prototype hardware.
• Perform Root Cause Analysis (RCA) on design failures by reproducing failure modes in simulation or the physical lab.
• Partner with cross-functional teams to validate integrated system performance and build simulation-based business cases.
• Develop institutional validation frameworks that scale across datacenter programs.
• Ensure deployed systems are validated against realistic failure scenarios and load transients.

• Employees at Amazon are often offered comprehensive health benefits—including multiple medical plan options (no pre-existing condition exclusions, 100% covered in-network preventive care), dental and vision plans, a 24/7 medical advice line from day one, expert second-opinion services, and broad mental-health support with several free counseling sessions (including pediatric). Financial wellness typically includes a 401(k) with company match (up to 2%), Restricted Stock Units (equity), FSAs, an emergency savings program, product and partner discounts, and even college-savings and home-purchase programs. Overall, the package is designed to support employees and their families’ health, finances, and day-to-day life.
