HVAC / Refrigeration Engineer

About the Role

KALT Refrigeration is looking for a technically strong and hands-on HVAC / Refrigeration Engineer to lead the development, testing, optimization and quality of our commercial refrigeration products. The selected candidate will play a key role in taking products from concept to production, ensuring that every refrigeration system delivers the required cooling performance, energy efficiency, reliability, and production quality.

Key Responsibilities

1. Product Development

• Develop new commercial refrigeration products from concept, prototype and testing through production.
• Design and select suitable refrigeration systems and components based on product requirements.
• Develop and improve refrigeration circuits, component selection, and system configuration.

2. Refrigeration System Optimization

• Optimize refrigeration systems for cooling performance, energy efficiency, and reliability.
• Analyze compressor, condenser, evaporator, expansion device and refrigerant selection.
• Troubleshoot refrigeration performance issues and implement engineering improvements.

3. Testing & Validation

• Plan and conduct product performance testing, including cooling, pull-down, temperature stability, energy consumption, defrost and reliability testing.
• Analyze test results and make necessary design modifications before production release.
• Establish standard testing procedures and performance benchmarks for products.

4. Production & Quality

• Review refrigeration production processes and ensure products are manufactured according to engineering specifications.
• Monitor critical processes such as piping, brazing, vacuuming, refrigerant charging, and leak testing.
• Identify production issues, conduct root-cause analysis, and implement corrective actions.

5. Continuous Improvement

• Reduce energy consumption, production defects, rework, and field failures.
• Improve product reliability and manufacturing efficiency.
• Evaluate new components, technologies, and refrigeration solutions for future products.

6. Technical Support

• Provide technical support to production and service teams.
• Analyze field failures and customer complaints and convert them into product improvements.
• Prepare and maintain technical specifications, BOMs, test reports, and engineering documentation.

Required Technical Skills

• Strong knowledge of commercial refrigeration systems and the vapor-compression cycle.
• Practical knowledge of compressors, condensers, evaporators, TXVs/expansion devices, and refrigeration controls.
• Good understanding of refrigerant charging, vacuuming, leak testing, superheat, and subcooling.
• Ability to troubleshoot refrigeration systems using actual operating data.
• Understanding refrigeration controls and defrost systems.
• Good knowledge of thermodynamics and heat transfer.
• Proficiency in MS Excel and basic engineering/CAD tools.

We are looking for someone who is:

• Hands-on and technically strong
• Comfortable working both in the engineering office and on the factory floor
• Strong in problem-solving and troubleshooting
• Data-driven and focused on efficiency
• Capable of taking ownership of product development
• Interested in building and improving products rather than only maintaining existing systems

Core Objective of the Role

To develop reliable, energy-efficient and commercially competitive refrigeration products for KALT Refrigeration, while establishing strong engineering, testing and quality standards for production.
