We are seeking an experienced and innovative Seismic Engineer to join our growing team and help transform industrial heat at scale. This role offers the opportunity to work on a first-of-its-kind energy technology with tangible, real-world climate impact, supporting the development and deployment of large-scale hardware systems.

As part of the Structural Engineering team within the Product Engineering organization, you will support seismic analysis, design and qualification efforts across Rondo’s Heat Battery System. You will work closely with structural, mechanical, process, electrical, controls, manufacturing, and project delivery teams to ensure designs are robust, code-compliant, constructible, and deployable across a wide range of seismic regions.

Your work will directly influence product reliability, project execution, permitting success, and the scalability of Rondo's technology platform.

Join us in reducing integral CO₂ emissions by 1% in 10 years—and 15% in 15 years.

What You Will Do

Key responsibilities include, but are not limited to:




- Perform Discrete Element Method (DEM) and Finite Element Method (FEM) analyses using appropriate tools and engineering methods.
- Develop automated analysis workflows for DEM and FEM simulations, including model generation, data extraction, post-processing, visualization, and reporting.
- Document engineering inputs, assumptions, methodologies, and analysis results, and communicate findings through clear, well-organized technical reports and presentations.
- Develop and execute model validation and calibration plans using shake table testing data and experimental measurements.
- Perform seismic hazard assessment and develop seismic design criteria and seismic calculation packages using applicable codes and standards across multiple geographies and regulatory jurisdictionsinternationally.
- Evaluate seismic demand on various structural and mechanical systems, enclosures, equipment supports, ducting, and various m
