Mechanical engineer jobs in California

About the role

We are looking for a hands-on Senior Mechanical Engineer to join our Core Technology team, focused on the design and development of hot air handling systems for high-temperature energy storage applications. This role is central to delivering robust ducting networks, plenum assemblies, dampers, louvers, and associated air-distribution equipment that operate reliably at elevated temperatures.

What you'll bring

• Bachelor’s or Master’s degree in Mechanical Engineering or a related discipline.
• 7+ years of engineering experience with a focus on air systems, industrial gas handling, or high-temperature process systems
• Proven track record of taking designs from concept through fabrication and commissioning for one or multiple of following systems: Dampers, actuators, louvers, ducts, plenum, furnace
• Experience with high temperature equipment design.
• Experience with high-temperature materials: stainless steels, Inconel, refractory linings, ceramic fiber insulation, and high-temperature expansion joint materials.
• Knowledge of relevant codes and standards (e.g., API, ASME, NFPA, applicable EN standards for industrial ducting and pressure equipment).
• Strong cross-functional collaboration and communication skills
• ability to work effectively with construction, commissioning, and operations teams.
• Demonstrated commitment to engineering rigor, quality documentation, and schedule execution.
• Track record of driving cost reduction through design optimization and standardization.
• Experience mentoring and developing junior engineers with authenticity and care.
• Experience working in an industrial construction environment (site supervision, field engineering).
