Job Description
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.
