Co-Simulation Engineer III

This is a fully remote position, open to applicants in United States.

📋 Description

• Collaborate with senior design teams to create multi-domain co-simulation and digital twin capabilities for the design and construction of data centers.

• Conduct computational fluid dynamics (CFD) modeling for data centers and their related internal and external environments.

• Work with design teams to establish co-simulation goals, performance metrics, acceptance criteria, prerequisites, assumptions, and initial conditions.

• Identify coupling strategies and model boundaries across 1D networks, 3D CFD, and control systems.

• Develop thermo-hydraulic flow-network models for chilled water and liquid cooling systems, including components such as pumps, valves, heat exchangers, CDUs, manifolds, and cold plates.

• Construct and sustain steady-state and transient system-level models, accounting for redundancy/failure-mode scenarios and the impacts of control logic.

• Create co-simulation interfaces between 1D networks and 3D CFD/thermal models, overseeing data exchange, time steps, and convergence.

• Execute pressure-drop, flow-balancing, and heat-rejection analyses to confirm design intent and assist in equipment selection and sizing.

• Develop and maintain simulation-ready schematics, component libraries, metadata, reusable model assets, and digital twin workflows.

• Create or assess model setups, boundary conditions, solver settings, co-simulation time steps, and quality checks.

• Draft and review co-simulation reports that document assumptions, methodologies, results, and design recommendations.

• Aid in proposals that outline the modeling scope, schedule, and budget.

• Present modeling findings, interpret results, and offer engineering recommendations to clients and internal stakeholders.

• Oversee modeling tasks, resource forecasting, coordination, version control, and management of model assets/scripts.

• Conduct QA/QC peer reviews of co-simulation models.

• Validate and calibrate system/co-simulation results utilizing analytical techniques and real-world data.

• Gather and reconcile BMS/SCADA data, along with flow, temperature, and pressure measurements for model calibration.

• Prepare validation and calibration reports that detail comparisons, uncertainties, limitations, and performance envelopes.

• Collaborate with CFD, design, commissioning, operations, and project management teams.

• Address technical inquiries related to modeling assumptions, results, and design implications.

• Review and approve model updates based on validation outcomes and project modifications.

• Generate progress reports, issue logs, model status updates, assumptions logs, revision histories, and RFI responses.

• Update model libraries, coupling scripts, and project documentation.

• Track personal hours using company tools.

• Utilize AI-enabled and digital tools to enhance efficiency and the quality of work.

• Complete assigned tasks and deliverables punctually and within budget.

• Perform additional related duties as required.

⛳️ Requirements

• Bachelor's degree in Mechanical Engineering or a related engineering discipline, with five years of experience in a consultancy environment; OR a Master's or PhD in Mechanical Engineering or a similar relevant field with two years of consultancy experience.

• Strong comprehension of thermodynamics, heat transfer, and hydraulics, including pump/valve/pipe networks and their control impacts.

• In-depth knowledge of chilled water systems, including flow control, balancing, and operational envelopes.

• Experience with hydraulic/flow-network tools such as Flownex, Siemens Flomaster, Aspen HYSYS, or similar.

• Proficient in at least one CFD tool for data center and equipment analysis, such as Cadence Reality DC Design, ANSYS Fluent, Siemens STAR-CCM+, or equivalent.

• Capable of interpreting P&IDs and MEP design documents.

• Familiarity with AutoCAD/Revit is advantageous.

• Knowledge of hyperscale data centers and liquid-cooled applications is a plus.

• Programming skills in Python, C/C++, MATLAB, or similar are beneficial.

• Proficient in MS Office Suite: Excel, Word, Outlook, PowerPoint, and Teams.

• Exceptional organizational, file-management, accuracy, and attention-to-detail skills.

• Ability to thrive in a remote work environment with effective communication, self-motivation, proactiveness, and resourcefulness in a distraction-free setting.

• Proficient in interpreting results and communicating effectively both in writing and verbally to both technical and non-technical audiences.

• Capability to adhere to company and site safety requirements.

• Skilled in analyzing and preparing documents, reports, and correspondence.

• Ability to engage directly with clients and sometimes serve as the main point of contact.

• Competent in working independently and collaboratively as part of a team with moderate supervision.

• Proficient in managing multiple tasks across concurrent modeling efforts.
