Staff Mechanical Engineer

Responsibilities

• Lead mechanical design of fuel cell power systems, including structural frames, enclosures, ballast and counterweight integration, thermal management, and hydrogen storage and delivery hardware.
• Own mechanical work products through the phase-gate process, including design reviews, drawing releases, and engineering change control.
• Lead and influence development and maintenance of 3D CAD models, 2D drawings with GD&T, BOMs, and engineering documentation to release-quality standards.
• Perform and review engineering analysis: structural (FEA), thermal, vibration/shock, tolerance stack-ups, and pressure system calculations (e.g., PRV sizing per API 520).
• Design hydrogen-wetted components and plumbing in compliance with applicable codes and standards (NFPA 2, UL 2267, IEC 62282, CGA guidance); enforce hydrogen-compatible material selection and fitting practices.
• Lead root cause analysis and corrective action for mechanical failures in test and field units; feed lessons learned back into design standards.
• Define and support DV test plans; participate in design verification and production readiness reviews.
• Interface with suppliers to improve product design.
• Mentor and technically guide mechanical engineers and designers; review work products and raise the team's design standards.

Required Qualifications / Experience

• Bachelor’s degree in mechanical engineering (M.S. Preferred)
• 10+ years of mechanical design engineering experience
• Working knowledge of pressure systems design, fittings and tubing practices, and material compatibility for gaseous service.
• Strong fundamentals in structural and thermal analysis; able to perform hand calcs and direct FEA work.
• Proficiency in 3D CAD (SolidWorks, Creo, or NX) and drawing standards including GD&T (ASME Y14.5).
• Experience with formal engineering change control (ECO/CCB processes) and configuration management.
• Experience leading design reviews and mentoring engineers.
• Strong written and verbal communication, teamwork, and technical analysis.
• Able to critically analyze data, new processes, and technical documents
• Innovation and growth mindset
• Desire to work in a hands-on environment

Preferred Qualifications

• Experience with hydrogen systems, fuel cells or compressed gas.
• Familiarity with NFPA 2, UL 2267, IEC 60079.
• Experience with powered industrial trucks (forklifts) or comparable motive applications.
• Experience with DFMEA, root cause analysis methods (5 Whys, fishbone, 8D), and reliability engineering.
