Senior Fluent Simulation Designer

Job Title

Senior Fluent Simulation Designer

Job Description

Job title:

In this role, you have the opportunity to lead mechanical and fluid simulation activities to support cooling unit and pump system design, enable root cause identification of field issues, and improve product reliability through simulation-driven engineering decisions.

Your role:

Design Simulation

Define simulation scope and methodology for cooling unit and pump system (CFD / thermal / flow / structural where applicable)

Build and maintain simulation models to support product design and architecture decisions

Perform simulation-based trade-off analysis (performance vs reliability vs cost)

Problem Solving

Support and lead simulation-driven root cause analysis for cooling unit / pump field issues

Correlate simulation results with field failure data and test results

Provide clear technical conclusions to support CAPA definition

Methodology and Model Reliability

Establish and improve simulation methodology and modeling standards

Drive correlation between simulation and test results (accuracy improvement)

Identify modeling gaps and continuously improve prediction capability

Support system level verification

Support definition of validation strategy by predicting risk scenarios

Identify critical stress / boundary conditions through simulation

Work with testing team to refine test conditions and improve efficiency

Quality and Design Process

Support design assurance and compliance activities through simulation evidence

Contribute to FMEA by providing simulation-based risk inputs

Ensure traceability of simulation assumptions and results

Cross team and supplier support

Collaborate with CU design, generator, and system teams to align simulation assumptions

Support supplier technical discussions (especially pump performance & limitations)

Provide simulation insights to support supplier issue resolution

You're the right fit if:

Education & Core Expertise

Master or PhD in Mechanical Engineering / Thermal Engineering / Fluid Mechanics or related

Strong fundamentals in fluid dynamics, heat transfer, and mechanical behavior

Simulation Expertise

Hands-on experience in CFD simulation (ANSYS Fluent / CFX / COMSOL etc.)

Experience with pump / flow / cooling system simulation preferred

Ability to build and simplify models based on engineering judgment

Engineering Application

Ability to correlate simulation results with test and field data

Experience supporting design decisions using simulation

Understanding of cooling unit or pump system is a strong plus

Tools

CFD tools: ANSYS Fluent / CFX / COMSOL

Mechanical tools: ANSYS / ABAQUS (basic structural understanding)

Data post-processing and analysis capability

Soft Skills

Strong analytical and problem-solving mindset

Ability to translate simulation results into clear engineering conclusions

Proactive communication with cross-functional teams

Ownership and ability to drive topics independently
