Last Energy is seeking a Senior Sales Engineer to support counterparty management and deal execution for our micro-modular nuclear power plant pipeline. This role sits at the intersection of technical credibility and commercial execution — you will be the person in the room who can speak fluently to a data center infrastructure team about power delivery, thermal management, and interconnection requirements, and then turn around and help close the deal. The ideal candidate comes from a technical sales background in power equipment, fuel cells, or electrical systems sold into energy-intensive industries, and brings at least 8 years of experience bridging engineering and commercial functions.
