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.
Key Responsibilities
Lead the mechanical design of hot air ducting systems, plenum assemblies, and air distribution components operating at temperatures up to 1000 °C.
Design, specify, and validate dampers (isolation, control, backdraft, and diverter types) and louvers for high-temperature service, including actuator selection and leakage performance requirements.
Design plenum assemblies, transition pieces, expansion joints, and support structures that accommodate thermal growth while maintaining structural integrity.
Define subsystem requirements and develop verification and validation (V&V) plans aligned with system-level performance, safety, and operational goals.
Prepare technical documentation—drawings, specifications, and engineering calculations—for internal teams, fabricators, and external stakeholders.
Perform thermal and fluid analyses to identify key design drivers; use FEA where required to confirm mechanical performance under thermal and pressure loads.
Lead and contribute to FMEA activities to identify and mitigate risk; develop and execute test strategies, including design of experiments (DOE), to validate system performance and reliability.
Support prototyping, test plans, vendor qualification, and iterative development across high-temperature metallic and insulated duct assemblies.
Lead the air circulation sub-system for product development of Rondo’s current and next generation product line. Follow Rondo product development phase gate process, lead Rondo product development reviews and maintainphase gate documentation.
Develop top level system architecture for Rondo Heat Battery Air Management and Heat Delivery systems.
Lead and participate in design reviews, schedule planning, and cross-functional progress reporting to drive program execution.
Utilize CAD and PLM tools (SolidWorks preferred) for design, documentation, and configuration control of air-system components.
Collaborate with manufacturing, construction, and supply chain teams to improve quality, establish process controls, and resolve root causes of field failures.
Develop duct sizing, routing, and layout using first-principles pressure drop calculations and 1D flow network analysis, ensuring compliance with velocity, pressure, and thermal expansion requirements.
Solve coupled multiphysics problems involving heat transfer (conduction, convection, radiation), fluid flow, and structural behavior in high-temperature air systems.
