Columbus, IN, United States Kasmo Global Full time
Job Title: CFD/Aftertreatment Engineer - MATLAB/ Simulink
Location: Onsite - Columbus, IN

Job Description:

We are seeking a skilled and motivated MATLAB/Simulink and CFD Engineer to support the development and simulation of diesel exhaust after-treatment systems. This role will be primarily onsite in Columbus, IN, with collaboration across global engineering teams and external catalyst suppliers.

The ideal candidate will bring strong expertise in MATLAB/Simulink modeling, thermal-fluid sciences, and computational fluid dynamics (CFD), with an emphasis on catalyst modeling and system simulation of components such as DOC, DPF, SCR, and NASD.

Key Responsibilities:

MATLAB / Simulink Focus:
  • Develop, calibrate, and validate aftertreatment component models (DOC, DPF, SCR, NASD) using engine test data or synthetic data.
  • Create complete system-level models and support simulation via MATLAB Simulink.
  • Develop and utilize S-functions, FMU models, and automation tools for simulation and post-processing.
  • Conduct model validation and calibration development using ECU/ECM data.
  • Support Hardware-in-the-Loop (HiL) and Software-in-the-Loop (SiL) applications for early-stage control software validation.
  • Use AVL Cruise M as the primary simulation tool for system-level modeling and performance evaluation.
Catalyst Modeling:
  • Work with internally developed and supplier-provided catalyst models.
  • Evaluate and enhance model accuracy and robustness.
  • Develop user-friendly analytical tools in MATLAB for use by internal engineering teams.
Cross-functional Collaboration:
  • Work closely with product business units (BUs), calibration engineers, and catalyst suppliers to support integration and validation efforts.
  • Improve existing modeling processes and simulation workflows.
CFD Requirements (Secondary/Optional Role Support):

Tool Utilization:
  • CAD Cleanup / Meshing: Ansys Workbench, SpaceClaim, ICEM (Hex/Tetra), Fluent Meshing, ANSA, STAR-CCM+
  • Solvers: Ansys Fluent, Ansys CFX, STAR-CCM+
  • Post-Processing: Ansys CFD Post, Fluent, STAR-CCM+
Domain Areas:
  • Automotive and industrial exhaust after-treatment systems
  • Under-hood and exhaust filter thermal simulation
  • Combustion, cooling jacket, and rotor-stator heat transfer analysis
  • HVAC and data center airflow analysis
  • Electronic component cooling, oil-water-gas separation, and power plant systems
Technical CFD Areas:
  • Steady/Transient state simulation
  • Conjugate heat transfer (CHT)
  • Multiphase and multispecies transport
  • Particle tracking simulations
Required Qualifications:
  • Bachelor's or Master's in Mechanical, Automotive, Chemical, or related Engineering discipline.
  • Minimum 5 years of hands-on experience in MATLAB and Simulink for system modeling and simulation.
  • Academic or professional experience in chemical reaction kinetics, catalysis, or heat/mass transfer is preferred.
  • Exposure to engine control modules (ECMs/ECUs) and aftertreatment calibration workflows.
  • Strong analytical and communication skills.
Nice to Have:
  • Experience with AVL Cruise M (training can be provided).
  • CFD simulation experience (using Ansys, STAR-CCM+).
  • Background in automotive exhaust systems, fluid-thermal systems, or powertrain modeling.
