Mechanical Design Engineer

Job Description

Tesla Energy is bringing battery, solar, and charging technologies to the grid, establishing new industries and defining the future of renewable energy ecosystems. This team is at the forefront of how we will generate, distribute, and consume power today and in the future.  

As part of the Industrial Storage Design Team, you will contribute to the system mechanical design of the Battery Energy Storage Systems (BESS) products such as Megapack and Powerpack that help make Tesla Energy products world class, working with a highly motivated and interdisciplinary team that rethinks how these products should be designed from the ground up, starting from blank page designs and building up to the top-level system design ownership with a first principles design approach. 

The role is collaborative and cross-functional, requiring extensive interfacing with teams including but not limited to systems engineering, parallel design teams, electrical/firmware engineering, validation test, manufacturing, service, to name a few. This role requires the ability to apply engineering fundamentals to design products that are at the core of Tesla’s success.  Our team is composed of individuals who are thoughtful, fast-moving, self-motivated, who love to solve difficult problems, and are team players.  

Job Responsibilities

• End-to-end ownership of the BESS system mechanical design for new and existing Tesla Energy products, ensuring the designed parts and system meet requirements and can successfully scale into mass production 
• Component and system mechanical design ownership of entire BESS products; converting requirements into design concepts and materializing these concepts into physical, validated, mass-production-ready parts/systems 
• Build-to-print mechanical design component design ownership, inclusive of system PCBA mechanical integration, sheet metal parts, plastics, harness integration, sealing/gasket designs, etc.
• Collaborate with cross-functional teams to refine requirements and specifications to optimally achieve product performance, schedule, cost, reliability, and quality targets 
• Develop and execute component and subsystem design validation plans and test methods to validate product adherence to requirements, in collaboration with parallel validation and systems engineering teams 
• Travel to support production launch and ramp (supplier visits, on-site at Tesla factories, etc.) 

Job Requirements

• Bachelor's Degree in Mechanical Engineering or equivalent relevant experience
• 2+ years of product design experience 
• Full product responsibility, from concept through production launch and ramp 
• Proficiency in CAD modeling (CATIA preferred), PLM/engineering change systems, and GD&T with a thorough understanding of tolerances and development of high-quality drawing packages/manufacturing instructions for parts and assemblies 
• Experience in multi-disciplinary analysis including structural FEA, vibration/dynamic analysis, thermal analysis, bolted joints, fatigue, etc, and the ability to efficiently simplify analysis  
• Understanding of material sciences of components used in mechanical design (metals, insulators, plastics, connectors, gaskets, etc.) and their fabrication processes (injection molding, thermoforming, casting, forging, stamping, extruding, brazing/welding, plating, heat treating, plating, machining, etc.) 
• Experience designing for high-volume manufacture and assembly, both manual and automated 
• Experience with electrical systems up to 2kV, voltage insulation, EMC&EMI, and power transmission
• Familiarity with design for reliability/FMEA concepts, PCBAs/electrical systems, and designing products for outdoors environments 
• Detail-oriented personality with solid documentation and reporting skills, excellent communication skills, and the ability to work in a fast-paced and challenging environment
