STAR-CCM+ CFD Specialist

Job Title: STAR-CCM+ CFD Specialist

Location: Remote

Job Type: Full-Time

Start Date: September 2025

Experience: 8+ years

• We are seeking a skilled and motivated STAR-CCM+ CFD Specialist to join our remote engineering team on a full-time role.
• In this role, you will take ownership of complex CFD simulations to support product development, innovation, and optimization efforts across various projects.
• You’ll work in a collaborative, fast-paced environment with cross-functional teams including mechanical design, product development, and R&D. Your contributions will play a key role in advancing our technology and delivering high-quality results to our clients.

Responsibilities & Must-have Skills

I. General CFD & Problem Understanding:

• Ability to independently approach CFD problems from initial understanding to final analysis and results.
• Experience handling complex and challenging CFD projects, including problem-solving strategies for technical difficulties.

II. Conjugate Heat Transfer (CHT):

• Experience setting up, running, and post-processing Conjugate Heat Transfer (CHT) simulations, particularly for pressure vessels and internal components.
• Strong understanding of mesh interfaces, boundary conditions, and challenges specific to CHT problems.

III. StarCCM+ Proficiency:

• Hands-on experience with StarCCM+, including:
• Geometry import, cleanup, and meshing preparation.
• Selection and application of meshing strategies (polyhedral, trimmed cell, mesh refinements).
• Setting up physics continua, solver configurations, and boundary conditions.
• Creating monitors, reports, and scenes for real-time solution tracking and post-processing.
• Familiarity with StarCCM+ features and challenges, particularly related to CHT and potential DEM simulations.

IV. Discrete Element Method (DEM):

• Knowledge of critical parameters, calibration steps, and best practices for setting up accurate DEM simulations.
• Experience coupling DEM with CFD for multiphase or particle-laden flow simulations.

V. Meshing & Pre-processing:

• Strong skills in handling complex or "dirty" CAD geometry for CFD readiness.
• Experience with mesh quality assessment, mesh refinement strategies, and balancing computational cost with accuracy.

VI. HPC & Workflow Management:

• Experience running CFD/DEM simulations on HPC clusters, including knowledge of job schedulers, parallel execution, and remote data management.
• Familiarity with cloud-based HPC platforms (e.g., Google Cloud) is a plus.
• Ability to work independently, manage simulation projects, use version control (e.g., Git), and maintain thorough documentation and reporting.

VII. Reacting Flows (Future Requirement):

• Theoretical knowledge or practical experience in simulating reacting flows (e.g., chemical reactions, combustion processes) is advantageous for future projects.

Qualifications

• 8+ years of hands-on experience using STAR-CCM+ in a professional or research setting
• Strong foundation in fluid mechanics, thermodynamics, and numerical methods
• Bachelor's or Master’s degree in Mechanical Engineering, Aerospace Engineering, or a related field
• Demonstrated ability to work independently and manage simulation tasks end-to-end
• Strong communication skills, especially in a remote team setting
• Experience with simulation post-processing and results visualization
