Job description

Job Title;Design Engineer Location: Coimbatore, Tamil Nadu Qualification:Diploma / B.E. / B.Tech in Mechanical Engineering, Refrigeration & Air Conditioning, HVAC,or related field. Experience:Design Engineer: 3–5 years in chiller / HVAC / refrigeration equipment design Salary: 35K to 50K (Negotiable for Right Candidate) Reporting To: Director 1.Role Summary; The Design Engineer will be responsible for designing industrial chillers, HVAC systems, heat exchangers, piping layouts, electrical coordination drawings, and related technical documentation. The role requires strong understanding of refrigeration, heat load calculations, component selection, manufacturing requirements, and customer-specific technical requirements. The Design Engineer must coordinate with Sales, Purchase, Production, QC, Electrical, Service, and Project teams to ensure accurate design, timely documentation, and smooth execution of chiller projects. 2. Key Responsibilities; A. Technical Design & Calculation; Prepare heat load calculations based on customer process requirements. Select suitable chiller capacity, compressor, condenser, evaporator, expansion valve, refrigerant, pumps, tanks, fans, and accessories. Prepare technical selections for air-cooled and water-cooled chillers. Calculate water flow rate, pressure drop, pipe size, tank capacity, buffer tank requirement, and pump head. Prepare refrigeration cycle calculations including evaporating temperature, condensing temperature, superheat, subcooling, and safety margins. Support design for special applications such as oil chillers, glycol chillers, brine chillers, batching plant chillers, anodizing chillers, effluent chillers, heat pumps,and process cooling systems. B. Drawing & Documentation; Prepare General Arrangement drawings, P&ID, piping layout, sheet metal drawings, coil layout, tank drawings, skid layout, and fabrication drawings. Prepare 2D and 3D drawings using AutoCAD / SolidWorks or equivalent software. Prepare technical specification sheets for customer approval. Prepare Bill of Materials with correct component specifications. Maintain drawing revisions and ensure only approved drawings are released for production. Prepare operation sequence and design notes for PLC/electrical team whenever required. C. Production & Purchase Support; Coordinate with Production team to clarify drawing, assembly, and fabrication doubts. Coordinate with Purchase team for technical specifications of compressors, heat exchangers, fans, pumps, valves, electrical items, and bought-out components. Verify material availability and ensure design is practical for manufacturing. Support standardization of chiller models to reduce manufacturing time and cost. Assist in resolving technical issues during fabrication, assembly, testing, and dispatch. D.Sales & Customer Support; Support Sales team with technical inputs for enquiries and quotations. Review customer requirements and prepare suitable technical offers. Attend technical discussions with customers when required. Provide clarification for customer comments on drawings and technical documents. Support project-specific customization without affecting reliability and serviceability. E.Quality & Testing Support; Support QC team during inspection and testing of chillers. Verify design parameters during testing such as water temperature, pressure, flow,refrigerant pressure, compressor current, and safety cut-off operation. Assist in troubleshooting issues related to design, component selection, refrigerant circuit, water circuit, and control logic. Record design corrections and implement improvements in future projects. F.Continuous Improvement; Improve existing chiller models for better efficiency, compactness, serviceability,and cost control. Maintain standard design templates, calculation sheets, BOM formats, and drawing libraries. Suggest design improvements based on service feedback and production issues. Reduce design errors, rework, material wastage, and customer complaints. 3.Required Technical Knowledge; Refrigeration and air-conditioning fundamentals. Industrial chiller working principles. Compressor, condenser, evaporator, expansion valve, refrigerant, pump, tank, and piping selection and selection software. Heat load calculation and TR calculation. Air-cooled and water-cooled chiller design. Basic electrical understanding. AutoCAD and SolidWorks. BOM preparation and manufacturing drawing practices. Knowledge of refrigerants such as R407C, R410A, R404A, R134a, etc. Understanding of industrial process cooling applications. 4.Required Skills; Strong technical calculation ability. Good drawing and drafting skills. Practical manufacturing understanding. Problem-solving mindset. Coordination with multiple departments. Good communication skills. Ability to work under project deadlines. Attention to detail in drawings, BOM, and technical documents. Willingness to learn new chiller applications and improve designs continuously. 5. Key Performance Indicators; Accuracy of design calculations. Timely completion of drawings and BOM. Reduction in production rework due to design errors. Number of standardized models developed.
