About Rondo Energy

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.

Join our team and together we can reduce world CO₂ emissions by 1% in 10 years, and by 15% in 15 years!
