**Workplace:** on_site

**Department:** Product Development (7071100)

## Description

**General Role Description**

Design, develop, and validate mechanical systems for outdoor photovoltaic (PV) and energy storage system (ESS) inverter platforms in order to ensure reliable performance, environmental protection, manufacturability, and serviceability in harsh outdoor conditions

## Requirements

·         Design mechanical systems for inverter platforms, including enclosures, structural frames, mounting systems, internal layouts, and component packaging, in order to meet product design and project requirements

·         Develop 3D models, detailed drawings, bills of material, and engineering documentation for inverter assemblies in order to enable accurate manufacturing, assembly, and product release

·         Define mechanical architecture, clearances, accessibility, and serviceability requirements in coordination with electrical, thermal, controls, sourcing, manufacturing, and testing teams

·         Design outdoor-rated inverter enclosures and related mechanical systems in order to address ingress protection, ventilation, sealing, condensation control, corrosion, solar loading, ambient temperature, altitude, acoustic, and vibration requirements

·         Integrate cooling components, airflow paths, ducting, heat sink structures, fans, heat exchangers, pumps, and related mechanical features in collaboration with thermal and electrical teams

·         Perform structural, vibration, tolerance stack-up, manufacturability, and thermal-stress evaluations in order to validate mechanical designs and reduce product risk

·         Coordinate prototype builds, environmental testing, mechanical testing, and validation activities in order to confirm design performance and identify required design modifications

·         Analyze field issues and root cause findings in order to implement mechanical design improvements that reduce failures and improve reliability

·         Apply design for manufacturability, assembly, serviceability, and cost principles in order to improve fabrication, assembly, localization, supplier qualification, and lifecycle cost

·         Participate in design reviews and provide technical input to proposal, field, and client-facing activities as needed

**General Employee Accountabilities**

·         Bring full effort to bear on tasks assigned by manager

·         Give manager best advice

·         Give earliest notice when work cannot be delivered as specified

·         Cooperate and collaborate with peers and interact cross-organizationally as specified by manager

·         Exemplify Company Core Values: Integrity, Client Focus, Team Orientation, and Personal Commitment

·         Comply with all Company policies, practices, and procedures and all regulations and laws

·         Recommend viable improvements proactively

·         Ensure effective utilization of business tools and processes

**Minimum Qualifications**

·         Bachelor’s degree in mechanical engineering, aeronautical engineering or related field, or equivalent via education and/or work experience

·         3 years of demonstrated experience in mechanical design for power electronics, inverters, switchgears, transformers, outdoor industrial equipment, or related mechanical systems

·         Demonstrated experience with 3D CAD tools such as SolidWorks, Creo, NX, or equivalent

·         Demonstrated experience with multi-physics simulations (FEA/CFD) using tools such as COMSOL, ANSYS Maxwell, etc.

·         Demonstrated understanding of structural design, materials, and manufacturing processes such as sheet metal, casting, machining, or related fabrication methods

·         Demonstrated understanding of thermal management and cooling systems for power electronics

·         Familiarity with environmental design requirements for outdoor equipment, including IP and/or NEMA ratings

·         Demonstrated successful working relationships with clients, suppliers, and other internal and external contacts

·         Demonstrated successful and positive personal leadership, interpersonal, organizational, administrative, and communication skills

·         Demonstrated continuous improvement in areas of responsibilities

·         Proficiency in Microsoft Office programs

·         Availability to travel domestically and internationally, less than 20% as needed, occasionally with limited notice

**Preferred Qualifications**

·         5 years of demonstrated experience in mechanical design for power electronics, inverters, switchgears, transformers, outdoor industrial equipment, or related mechanical systems

·         Demonstrated experience with designing equipment to meet UL, IEC, or other standards relevant to outdoor electrical equipment

·         Demonstrated experience with liquid cooling system design

·         Demonstrated experience working with global teams

·         Demonstrated experience with developing and onboarding relevant domestic and global suppliers
