• Solid understanding of single‑phase and two‑phase fluid dynamics, refrigerant mechanics, heat transfer, and thermodynamics.
• Familiarity with numerical methods and iterative approaches for refrigerant circuits and hydronic circuit systems.
• Knowledge of HVAC system operation, component balancing, and system integration.
• 1–2+ years of experience in thermal engineering is preferred; highly motivated new graduates are welcome.
• Proficiency in object‑oriented software and willingness to learn coding skills on the job.
• Practical application experience with main CFD simulation software, both one‑ and two‑dimensional.
• Highly self‑motivated, detail‑oriented, and proactive team player.
• Proficiency in Microsoft Office 365 (Excel, Word, PowerPoint) and communication tools (MS Teams, Outlook).
• Excellent verbal and written communication skills in English.
