Sr. Mechanical Design Engineer

Job Description:

Position Overview: 

We are looking for a Senior Mechanical Engineer with deep expertise in product design and development to join our Power Electronics team focused on renewable energy solutions. You will collaborate closely with cross-functional teams, including electrical, thermal, manufacturing, and industrial design to deliver high-performance, manufacturable, and reliable products. 

This role requires strong technical capabilities in CAD design, thermal and structural analysis, and a solid understanding of manufacturing processes—particularly for electronics enclosures and systems exposed to harsh environmental conditions. 

Key Responsibilities: 

• Lead the mechanical design of renewable energy power electronics products from concept to mass production. 

• Develop 3D models and 2D drawings using tools like SolidWorks, with full application of GD&T. 

• Perform thermal and structural FEA simulations to ensure mechanical reliability under environmental stress. 

• Design for manufacturability using plastic injection molding, sheet metal, die casting, and other high-volume production methods. 

• Integrate thermal management solutions for high-power density systems (e.g., heatsinks, airflow, phase-change materials). 

• Collaborate closely with electrical, thermal, manufacturing, and testing teams to ensure design feasibility and product robustness. 

• Manage design reviews, risk assessments (e.g., FMEA), and compliance with environmental standards (e.g., IP ratings, UL, IEC). 

• Support prototype builds, testing, root cause analysis, and continuous design improvement. 

Required Qualifications: 

• Bachelor's or Master's degree in Mechanical Engineering or a related field. 

• 8+ years of mechanical design experience, ideally in power electronics, or energy products. 

• Proficient in CAD modeling and drawing creation with a deep understanding of GD&T and tolerance analysis. 

• Demonstrated ability to perform structural and thermal analysis using FEA tools (e.g., ANSYS). 

• Hands-on experience designing for manufacturing across multiple processes—plastic, metal, and composite components. 

• Strong grasp of DFM/DFA principles and experience working with suppliers and contract manufacturers. 

• Excellent cross-functional communication skills with a proactive, problem-solving mindset. 

Preferred Qualifications: 

• Experience designing enclosures for outdoor, high-voltage, or grid-connected equipment. 

• Knowledge of thermal management techniques for power electronics in solar, wind, or energy storage applications. 

• Familiarity with environmental compliance standards (e.g., IP65/IP67, UL 1741, IEC 62109). 

• Exposure to reliability testing, accelerated life testing, or harsh environment validation (e.g., salt fog, vibration, thermal cycling). 

• Familiarity with high-volume manufacturing and global supplier collaboration. 

Why Join Us: 

• Contribute to a sustainable future through impactful renewable energy technologies. 

• Join a passionate and innovative engineering team working on clean energy solutions. 

• Competitive salary, benefits, and opportunities for career growth in a mission-driven company.
