Join the Team
We are on a mission to free global economies from petroleum-based fuels.
We have big ambitions, but we can’t do it alone.
About ClearFlame
At ClearFlame, we are on a mission to free global economies from a need for petroleum-based fuels in heavy-duty applications—simultaneously addressing climate impact and the energy equity and environmental justice issues that have a disproportionate impact on underrepresented populations globally.
We are breaking the bond between the diesel engine and diesel fuel, clearing the path to emissions reduction for hard-to-electrify applications, including heavy-duty trucking, power generation, and other off-highway markets.
Applicable to existing engines as well as new production, ClearFlame offers a rapid pathway to decarbonizing diesel-dominated sectors across the globe.
We are always looking for talented, passionate individuals to join our team.
