Senior System Modeling Engineer

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 System Modeling Engineer to join our dynamic team. By focusing on driving process modeling and system analysis through advanced thermal analysis, process simulation, and seamless integration of high-temperature heat into diverse industrial processes, this role will make a huge impact by enhancing Rondo Heat Battery (RHB) Systems across the globe.
Join our team and together we can reduce world CO₂ emissions by 1% in 10 years, and by 15% in 15 years!
