Rondo Energy's mission is to eliminate 15% of global CO2 emissions in 15 years.

To accomplish this mission, Rondo is deploying low-cost, zero-carbon Rondo Heat Batteries to accelerate the deployment of renewable energy and to significantly decarbonize industrial processes that are commonly thought of as "difficult-to-decarbonize". Our Heat Batteries charge from intermittent renewables to provide high temperature, continuous heat for customers safely, reliably, at an unprecedented 98% efficiency - and at a cost point that is lower than any other method.

We are looking for an experienced Thermal Engineer to join our dynamic team, dedicated to enhancing Rondo Heat Battery (RHB) systems. The ideal candidate will have a strong background in computational fluid dynamics (CFD), heat transfer, and thermodynamics.

  • Conduct comprehensive performance analyses to optimize thermal performance, efficiency, and reliability of existing and new products
  • Build 3D CAD models of RHB components using commercial CAD software packages
  • Assist in the validation of models through comparison with experimental data and field measurements
  • Generate detailed documentation of simulation results for internal and external stakeholders
  • Work closely with cross-functional teams to integrate thermal modeling insights into the overall product design process
  • Contribute to the development and improvement of in-house tools for thermal analysis

What You Will Bring:

  • Master’s degree in mechanical engineering, or equivalent industry experience
