Senior Mechanical Engineer

Noon Energy is a leader in long-duration energy storage developing battery technology that stores energy by splitting CO₂ eliminating reliance on rare metals. We are scaling from megawatt (MW) to gigawatt (GW) production of our energy storage products.

Our vision is a fully renewable future powered by nature-inspired energy storage. Our compact battery technology delivershours of storage using air-abundant molecules rather than rare metals enabling affordable on-demand renewable electricity.

We are seeking a Senior Mechanical Engineer with 710 years of hands-on experience to lead the design development and continuous improvement of mechanical systems and hardware products. This role spans concept through production and requires strong analytical capability technical ownership and the ability to work effectively across engineering disciplines. (

• Design and develop mechanical components assemblies and systems using CAD tools such as SolidWorks AutoCAD or equivalent.
• Own the full product lifecycle including 3D modeling detailed drawings P&IDs PFDs BOM generation and equipment specifications.
• Design and integrate complex process systems incorporating instrumentation such as thermocouples pressure sensors and flow meters.
• Perform engineering analyses including stress thermal fluid and tolerance stack-up analysis.
• Support the development of mechanical systems for demanding high-temperature operating environments.

• Create and maintain technical drawings specifications and engineering documentation in accordance with applicable industry standards and safety requirements.
• Apply GD&T principles and ensure designs comply with applicable codes and standards.
• Participate in and lead design reviews providing technical guidance to the broader engineering team.
