Responsibilities
Perform mechanical analysis and detailed design for AHUs, FCUs, BCUs and related subsystems including sheet metal, enclosure structures, panels, fan/motor assemblies, coil integration, and airflow pathways. Develop innovative design solutions for custom HVAC equipment based on customer-specific requirements and product performance targets. Execute design improvements that optimize manufacturability, serviceability, acoustics, energy efficiency, and product quality. Create and maintain mechanical engineering standards, CAD models, technical documentation, and design specifications. Develop design rules and logic used in configurable/dynamic BOM generation. Interpret and implement UL 60335-2-40 mechanical safety and A2L refrigerant requirements for clearances, airflow paths, compartment construction, and enclosure integrity. Coordinate with compliance partners and agencies to validate mechanical requirements and securement tests. Define and execute test plans in partnership with the Largo Test Lab (airflow performance, thermal testing, vibration, structural integrity). Lead prototype builds and fit-up verification for assembly feasibility and service access. Oversee testing of fans, motors, mechanical components; analyze data and drive corrective actions. Support manufacturing engineering with BOMs, routings, assembly sequencing, and DFM/DFA improvements. Evaluate mechanical vendors and qualify new components including fans, bearings, heating elements, insulation materials, and assemblies. Provide mechanical guidance to marketing, applications, sales engineering, service, and field teams. Generate clear and accurate drawings, installation details, and mechanical instructions. Support PFMEA reviews, root-cause analyses, corrective actions, and engineering change processes. Maintain consistency with Largo drafting/documentation standards and mentor drafters/designers.
