The result is a growing portfolio of best-in‑class, robust, and scalable fuel cell solutions. As we continue to expand our hydrogen fuel cell product line and enter new markets, we are seeking a highly motivated Mechanical Engineer to contribute to new product development, prototype testing, and lifecycle improvements. This is a hands-on, fast‑paced role ideal for engineers who thrive in a startup environment and enjoy working closely with cross‑functional teams.

Requirements

• 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.
• Ability to work hands‑on in prototyping and testing environments.
• Demonstrated desire to learn, adapt, and grow within a dynamic engineering team.

Nice To Haves

• Experience working in manufacturing environments, particularly assembly‑based production.
• Proficiency in SolidWorks 2023+ (CSWA certification a plus).
• Self‑starter with the ability to independently drive engineering tasks and projects.
• Knowledge of thermal systems, low‑voltage electrical systems, and common manufacturing materials.
• Experience with design for manufacturability across sheet metal, injection molding, metal casting, CNC machining, and rapid prototyping.
• Experience performing FEA or CFD simulations.
• Experience with PEM fuel cell systems (preferred but not required).

Responsibilities

• New Product Development
• 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.

Benefits

• Opportunity to contribute directly to next‑generation clean‑energy products.
• Fast‑paced, collaborative startup environment with significant ownership of projects.
• Hands‑on engineering work from concept through field deployment.
• Mission‑driven culture focused on innovation and sustainability.
