Perform detailed thermal load calculations (e.g., heat gain/loss, psychrometrics) to accurately size and specify system components like compressors, condensers, evaporators, and expansion valves.
Create and interpret detailed engineering drawings, schematics, and Piping and Instrumentation Diagrams (P&IDs) using CAD software like AutoCAD or Revit.
Select and source appropriate refrigeration equipment and components based on performance specifications, energy efficiency, cost, and lifecycle analysis.
Manage the full lifecycle of refrigeration projects, including budgeting, scheduling, procurement, and coordination with contractors, vendors, and internal teams.
Conduct thorough site surveys and feasibility studies for new installations or retrofits, providing detailed technical reports and recommendations.
Develop and implement robust preventative and predictive maintenance programs to maximize system uptime, reliability, and operational efficiency.
Diagnose and troubleshoot complex failures in industrial refrigeration systems, including ammonia, CO2, and HFC/HFO-based systems, and perform root cause analysis.
Ensure all designs, installations, and maintenance activities strictly adhere to relevant codes, standards, and regulations (e.g., ASHRAE, IIAR, EPA, OSHA).
Commission new and retrofitted refrigeration systems, verifying performance against design specifications and ensuring proper integration with building automation systems (BAS).
Prepare detailed technical documentation, including sequence of operations, service reports, compliance logs, and as-built drawings.
Provide expert technical support and guidance to field service technicians, maintenance staff, and facility operators.
Evaluate and recommend emerging technologies, alternative refrigerants, and control strategies to improve system performance and reduce environmental impact.
Oversee refrigerant management programs, ensuring strict compliance with EPA Section 608 regulations, including leak detection, repair, and meticulous record-keeping.
Develop and manage control strategies for refrigeration systems, programming and fine-tuning PLCs and integrating with facility-wide Building Management Systems (BMS).
Lead energy audits of existing cooling systems to identify opportunities for efficiency improvements, cost savings, and sustainability enhancements.
Review and approve contractor submittals, shop drawings, and requests for information (RFIs) to ensure compliance with project design intent.
Develop and conduct training sessions for junior engineers, technicians, and operations personnel on system operation, safety procedures, and new technologies.
Liaise directly with clients to understand their operational needs, present technical solutions, and manage expectations throughout the project lifecycle.
Implement and enforce rigorous safety protocols for working with high-pressure systems, hazardous materials (like ammonia), and electrical components, fostering a strong safety culture.

Secondary Functions

Support ad-hoc technical inquiries and exploratory analysis of system performance data.
Contribute to the organization's long-term energy efficiency and sustainability strategy.
Collaborate with facilities and operations teams to translate cooling needs into engineering specifications.
Participate in project planning meetings, design reviews, and cross-functional team collaborations.
