Atmospheric Water Generation (AWG) products.
About the Role
We are looking for an HVAC & Refrigeration Engineer to join the R&D / Product Engineering
team.
The role involves hands-on work across refrigeration system design, testing, optimization
and troubleshooting. You will work on vapor-compression refrigeration systems and
contribute to improving system performance, energy efficiency, reliability and overall product
performance.
This role would suit someone who enjoys working with physical systems, prototypes and test
equipment and is comfortable moving between design, experimentation, analysis and
troubleshooting.
Key Responsibilities
Refrigeration System Design & Optimization
● Design and optimize vapor-compression refrigeration systems.
● Perform refrigeration cycle analysis and system-level performance calculations.
● Select and size compressors, evaporators, condensers, expansion devices, fans and
related components.
● Optimize refrigerant charge, superheat, subcooling and operating parameters.
● Analyze cooling capacity, COP and overall system energy performance.
Thermal & Condensation Engineering
● Analyze heat transfer and condensation processes.
● Work on evaporator, airflow and heat-exchanger performance.
● Apply psychrometric and dew-point concepts to system performance.
● Identify opportunities to improve condensation and energy efficiency.
Testing & Experimental Development
● Design and conduct refrigeration and thermal performance tests.
● Develop test procedures and performance benchmarks.
● Collect and analyze temperature, pressure, humidity, airflow, electrical and
system-performance data.
● Prepare technical reports and recommend engineering improvements based on test
results.
Troubleshooting & Root-Cause Analysis
● Diagnose refrigeration and thermal issues in prototypes and deployed systems.
● Troubleshoot compressor performance, refrigerant flow, expansion devices, frosting,
pressure and airflow-related issues.
● Conduct root-cause analysis and implement corrective actions.
● Support technical resolution of field issues when required.
Product Development
● Support development and improvement of refrigeration-based products.
● Translate performance requirements into technical specifications.
● Support prototype development, testing and design iterations.
● Evaluate refrigeration components, heat exchangers, refrigerants and related
technologies.
Cross-Functional Collaboration
● Work with mechanical, electrical, controls and other engineering teams.
● Coordinate with manufacturing and service teams to ensure practical and reliable
designs.
● Support technical evaluation of refrigeration components and suppliers.
● Provide technical inputs during product testing and field deployments.
Required Qualifications
● B.E. / B.Tech / M.E. / M.Tech in Mechanical Engineering, Thermal Engineering,
Refrigeration & Air Conditioning, HVAC, Energy Engineering or a related discipline.
● 1-3 years of relevant industry experience in HVAC, refrigeration, thermal systems,
heat pumps, cooling systems or product engineering.
● Strong understanding of:
○ Vapor-compression refrigeration cycles
○ Thermodynamics
○ Heat transfer
○ Psychrometrics
○ Fluid mechanics
○ Refrigeration system components
○ HVAC system design and troubleshooting
● Practical experience in refrigeration testing, commissioning or troubleshooting.
● Ability to analyze engineering data and identify performance improvement
opportunities.
Preferred Experience
Experience with one or more of the following would be an advantage:
● Compressor selection and performance analysis
● Evaporator and condenser design
● TXV / EEV selection and optimization
