1D CFD Engineer

Roles and Responsibilities

Perform baseline CAE analysis of refrigeration and HVAC systems using 1D simulation tools.

Develop and optimize system models for refrigeration cycles, airflow distribution, and heat exchanger performance.

Evaluate system KPIs such as cooling capacity, COP (Coefficient of Performance), pressure drop, and energy efficiency.

Support design teams in delivering HVAC-compliant solutions within program timelines.

Drive test-to-CAE correlation for refrigeration systems, ensuring simulation accuracy.

Consider real-world constraints such as packaging, manufacturability, cost, and regulatory compliance.

Participate in model build, debugging, and validation of 1D simulation setups.

Collaborate cross-functionally with design, testing, and manufacturing teams in a fast-paced environment.
