• 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

Experience with commonly used refrigerants would be an added advantage.

What We're Looking For

• Strong technical fundamentals with hands-on engineering capability.
• Ability to independently troubleshoot and solve technical problems.
• Comfortable working with machines, prototypes and test equipment.
• Data-driven approach to engineering decisions.
• Interest in energy efficiency and thermal performance.
• Comfortable working in a fast-paced startup environment.
• Willingness to work across design, testing and field troubleshooting when required.

Why Join

• Work on real-world climate and water technology.
• Hands-on exposure to refrigeration and thermal product development.
• Opportunity to work across multidisciplinary engineering functions.
• High ownership and exposure to product development in an early-stage environment.
• Opportunity to contribute to technology addressing sustainability and resource

challenges.

Note: This is a hands-on engineering role. Candidates should be comfortable working from

the facility and participating in testing, troubleshooting and field activities when required.

Candidates are encouraged to highlight relevant experience in HVAC/refrigeration system

design, testing, commissioning, troubleshooting, thermal analysis or product

development in their resumes.
