Company

hirify.global develops materials and solutions for advanced electronics and high-tech industries.

What you will do

• Lead technical investigations into CMP fundamentals, material behavior, and process interactions.
• Build physics-based simulation models from first principles and optimize model architecture, meshing, solver settings, and runtime efficiency.
• Verify and validate simulations through numerical checks, experiments, calibration, and uncertainty assessment.
• Design validation experiments, develop parameter-identification methods, and use characterization tools to study polishing mechanisms.
• Analyze interactions between pad materials, solid and fluid mechanics, contact mechanics, tribology, wear, and semiconductor process conditions.
• Collaborate with research, applications, product development, manufacturing, data science, and external technical experts.

Requirements

• Master’s degree or Ph.D. in mechanical engineering, chemical engineering, materials science, physics, applied mathematics, or a related discipline.
• Less than five years of industrial experience applying scientific and engineering principles to complex technical problems.
• Experience with mathematical modeling of physical systems, experimental method development, computational modeling, data analysis, and scientific computing.
• Proficiency with MATLAB, Python, Maple, or similar technical computing environments.
• Expertise in areas such as transport phenomena, fluid mechanics, polymer mechanics, contact mechanics, fracture mechanics, tribology, surface characterization, or materials characterization.
• Ability to work across theory, simulation, experimentation, and characterization in multidisciplinary teams.

Nice to have

• Familiarity with CMP consumables, processes, polishing mechanisms, and polyurethane structure–property–performance relationships.
• Experience with finite element analysis, computational fluid dynamics, multiphysics simulation, model verification and validation, uncertainty quantification, or sensitivity analysis.
• Hands-on experience with ANSYS, Abaqus, COMSOL, or high-performance computing.
• Experience with numerical stability, convergence, mesh and time-step independence, model calibration, parameter estimation, and solver optimization.
