Responsibilities

• Design and develop mechanical and electromechanical components and systems for hydrogen fuel cell units.
• Create 3D models, assemblies, and detailed drawings using SolidWorks.
• Manage engineering files, revisions, and configuration control using PLM tools.
• Participate in preliminary, critical, and cross‑functional design reviews.
• Contribute to DFMEA activities and risk mitigation efforts.
• Develop BOMs and maintain accuracy throughout the product lifecycle.
• Support design release activities in collaboration with Quality, Manufacturing, and Purchasing teams.

Prototype Development, Testing & Validation

• Build, test, and validate prototype components and systems.
• Develop test protocols and validation plans for components and complete products.
• Analyze test data, prepare documentation, and communicate results to engineering leadership.

Lifecycle Engineering & Continuous Improvement

• Support fielded units and customer service teams with troubleshooting and root‑cause analysis.
• Drive cost‑reduction initiatives and identify opportunities for product improvement.
• Lead engineering change notices (ECNs) and update documentation as products evolve.
• Propose design enhancements that improve performance, manufacturability, or reliability.

Required Qualifications

• Bachelor’s degree or higher in Mechanical Engineering.
• 3–7 years of experience in mechanical design, new product development, or related engineering environments.
• Strong analytical, problem‑solving, and data‑interpretation skills.
• Excellent written and verbal communication abilities.
