CFD Engineer (Multiphase & Phase-Change Simulations)

Location: Goa

Employment Type: Full-time

About the Role

We are hiring a CFD Engineer with 4+ years of experience to lead and execute advanced simulations involving phase change and multiphase flows. You will work closely with our design team to translate 3D concepts into simulation-ready models, run high-quality CFD studies, extract actionable insights, and deliver optimization feedback supported by data.

Preferred Education

• Bachelor’s / Master’s degree (preferred) in Mechanical / Chemical / Aerospace Engineering (or equivalent)
• Strong practical simulation track record is essential regardless of degree level

Key Responsibilities

• Setup, run, and validate multiphase and phase-change CFD simulations, including:
• Evaporation, boiling, condensation, sublimation, deposition, and freezing
• Multiphase flow phenomena such as airfoils, propellers, vortex formations, and related flow structures
• Work with the internal team to:
• Take 3D CAD models and adapt them for simulation (cleanup, simplification, fluid domain creation, etc.)
• Perform meshing and preprocessing (boundary conditions, material models, solver setup, convergence strategy)
• Execute simulations using:
• SimScale and/or open-source CFD stacks capable of multiphase and phase change
• OpenFOAM, including custom solver setup and tailoring workflows for physics accuracy and runtime efficiency
• Develop and run custom UDFs/custom code (as applicable) for phase-change modeling and simulation customization
• Run simulations on virtual desktops / offline workstations / GPU or compute clusters with minimal assistance
• Post-process results and deliver:
• Tables, charts, plots, and clear graphical visualizations
• Structured comparisons across design iterations
• Derive conclusions from data and provide optimization recommendations to the design team
• Produce detailed technical reports documenting methodology, assumptions, results, limitations, and next steps

Required Qualifications & Skills

• 4+ years of hands-on CFD experience in industrial or applied R&D settings
• Strong working knowledge of:
• Thermodynamics
• Fluid mechanics / fluid flow
• Numerical methods and practical CFD modeling considerations (stability, convergence, mesh independence, etc.)
• Experience with at least one of:
• SimScale
• Other open-source / accessible simulation platforms supporting multiphase and phase change
• Strong OpenFOAM capability:
• Case setup, solver selection, turbulence modeling, multiphase configuration, mesh workflows
• Ability to create and execute custom functions/scripts/UDF-style extensions for phase-change use cases
• Practical experience preparing geometry and simulation inputs:
• Geometry cleanup and simplification
• Meshing (structured/unstructured as required)
• Preprocessing for stable and accurate runs
• Comfortable operating in compute environments:
• Virtual desktops, remote Linux systems, HPC-style workflows
• Familiarity with GPU/cluster workflows is a plus (where applicable)

Preferred / Nice-to-Have

• Strong CAD capability, preferably Fusion 360 (or similar)
• Experience with:
• Phase-change models (VOF, Eulerian multiphase, cavitation/boiling approximations, conjugate heat transfer, etc.)
• Propeller/airfoil simulations (MRF/sliding mesh, vortex capture, transient setups)
• Ability to balance accuracy vs compute cost and still deliver results within tight timelines
• Experience building standardized templates for reports, dashboards, and repeatable workflows

Soft Skills & Working Style

• Self-driven and able to run end-to-end simulation tasks with minimal guidance
• Strong communication skills:
• Explains assumptions and limitations clearly
• Converts complex results into actionable design feedback
• Organized documentation habits and consistent reporting

What Success Looks Like (First 5–15 Days)

• Independently delivers multiphase/phase-change simulation studies from CAD → mesh → run → post-process → report
• Establishes repeatable workflows for simulation setup and reporting
• Provides clear optimization insights that accelerate iteration cycles for the design team

• Resume + brief cover note
• Portfolio/examples (reports, plots, case studies) if available
• Tools used (OpenFOAM/SimScale/etc.), and which phase-change/multiphase problems you’ve solved
