Systems Modeling Mechanical Engineer, Fleet Remediation Engineering

About the role

As a Systems Modeling Mechanical Engineer, you will bridge the gap between physical infrastructure and virtual simulation. You will be responsible for creating, maintaining, and validating high-fidelity models of our data center cooling systems, using these models to optimize performance, predict failures, and validate innovative product designs (such as advanced liquid cooling or high-density air-handling units) before deployment. If you are passionate about innovative projects at hyper-scale and meet these qualifications, this role is for you!

Responsibilities

• Build and maintain high-fidelity system models of data center mechanical systems — including cooling infrastructure (CRAC/CRAH, DAHU, chillers, liquid cooling) and airflow environments — continuously calibrated against physical test data and field measurements.
• Develop and execute CFD simulations to predict thermal performance, pressure drop, airflow distribution, and failure modes across a range of operating conditions.
• Automate simulation workflows and "what-if" scenario testing using Python, MATLAB, or equivalent scripting tools to accelerate design iteration.
• Lead pre-deployment validation of new and FOAK mechanical products — including rear-door heat exchangers, cold plates, DLC systems, high-density air handling units, and advanced rack architectures.
• Design and execute Hardware-in-the-Loop (HIL) lab testing that replicates realistic datacenter loading scenarios, validating system behavior under conditions that mirror Day 1 field deployment.
• Define and own Design Verification Plans (DVPs) and test procedures for prototype hardware, covering thermal, pressure, flow, and transient response testing.
• Perform Root Cause Analysis (RCA) on design failures by reproducing failure modes in simulation or the physical lab, producing data-backed validation reports that support deployment sign-off decisions.
• Partner with cross-functional teams to validate integrated system performance and build simulation-based business cases for new technology adoption.
• Develop institutional validation frameworks — repeatable test methodologies, simulation standards, and acceptance criteria — that scale across datacenter programs.
• Ensure deployed systems are validated against realistic failure scenarios, load transients, and edge-case conditions to support Day 1 operational readiness.

Qualifications

• Education: Bachelor’s in mechanical engineering, Thermal Engineering, or a related field.
• Experience: 6+ years of experience in data center design, construction, or operations, with a strong focus on thermal modeling.
• Modeling Skills: Deep proficiency in CFD software (e.g., Ansys Fluent, Cadence, or similar).
• Scripting: Proficiency in Python, MATLAB, or C++ for data analysis and automation.
• Validation: Hands-on experience with mechanical test fixtures, sensors, and data acquisition systems (DAQ).
• Excellent communication and report-writing skills.

Preferred qualifications

• 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.
• Master's Degree in Mechanical Engineering, Thermal Engineering, or a related field.
