About Company
At Refroid Technologies, we are pioneering next-generation liquid cooling solutions that redefine how data infrastructure operates. From hyperscale data centers to high-performance edge environments, our modular and efficient systems are engineered to reduce energy consumption, maximize performance, and contribute to a greener planet. Refroid Technologies is at a growing stage and current plant is in IDA Jeedimetla however we are looking for a larger production plant in an around of Hyderabad. We already have order in hand to deliver for this financial year in the tune of INR 120 CR.
Position Summary
The Thermal Engineer will design, analyze, simulate, validate, and optimize advanced liquid immersion cooling solutions for AI, HPC, enterprise, edge, and hyperscale data centres. The role focuses on high-performance thermal management systems including immersion cooling tanks, Coolant Distribution Units, heat exchangers, and coolant-flow architectures, while ensuring reliability, manufacturability, and compliance with global standards.
Key Responsibilities
Product Design and Development: Design advanced immersion cooling systems for high-density data centres; develop thermal architectures for immersion pods, CDUs, manifolds, and heat exchangers; perform liquid-cooling calculations; optimize heat transfer for AI and HPC workloads; develop coolant circulation systems; and support new products from concept through commercialization.
Thermal Analysis: Perform CFD simulations, thermal performance modelling, coolant-flow analysis, pressure-drop optimization, heat-transfer evaluation, transient and steady-state analysis, and laboratory validation.
Prototype Development: Support prototype manufacturing, develop test methodologies, conduct validation, analyze performance, recommend improvements, and prepare engineering-change documentation.
Collaboration: Work with mechanical, electrical, controls, manufacturing, sales, presales, suppliers, certification agencies, and customers.
Product Validation: Develop test plans, conduct reliability and life-cycle testing, verify performance to specifications, and support certification activities.
Technical Competencies
Core Engineering: Heat Transfer, Thermodynamics, Fluid Mechanics, Thermal Management, Two-Phase Cooling, Single-Phase Immersion Cooling, Heat Exchanger Design, Pump Selection, Cooling System Design, and Refrigeration Principles. Simulation: ANSYS Fluent, ANSYS Icepak, SolidWorks Flow Simulation, COMSOL Multiphysics, Siemens STAR-CCM+, FloTHERM, MATLAB, and Python.
Mechanical Design: SolidWorks, Creo, CATIA, Autodesk Inventor, and AutoCAD.
Standards: TIA-942, ASHRAE, IEC, ISO 9001, ISO 14001, CE, UL, RoHS, and REACH.
Education & Experience
A Bachelor’s Degree in Mechanical Engineering, Thermal Engineering, or Energy Engineering is essential. A Master’s Degree in Thermal Engineering, Heat Transfer, Mechanical Design, or Computational Fluid Dynamics is preferred. Three to eight years of relevant experience is ideal, particularly across data-centre cooling, HVAC, liquid cooling, industrial cooling, semiconductor cooling, automotive thermal management, or aerospace cooling systems.
Key Deliverables & Performance
Deliver new immersion cooling products, thermal simulation reports, CFD models, product-design documentation, test reports, performance optimization, design-verification documents, and engineering-change requests. Key performance priorities include 95% or higher on-time product-development milestones, 95% or higher CFD correlation, 10% annual thermal-efficiency improvement, 98% product-validation success, first-time-right design quality, 5% or higher cost optimization, and customer technical-support SLA compliance.
