Job description

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.

Key Duties & Responsibilities

• Serve as the primary technical resource for prospective counterparties throughout the sales cycle, from initial qualification through contract execution
• Lead technical presentations, site assessments, and power requirement scoping sessions with customer engineering and infrastructure teams
• Support term sheet and contract negotiations by translating complex plant specifications into clear commercial terms counterparties can act on
• Develop and maintain deep knowledge of Last Energy's PWR-20 plant design, output characteristics, interconnection requirements, and delivery timelines
• Build and manage relationships with technical decision-makers at target accounts, including data center developers, hyperscalers, and industrial off-takers
• Collaborate closely with Last Energy's engineering, project development, and legal teams to ensure deal structures are technically and operationally feasible
• Identify and escalation technical risks or misalignments early in the deal process to protect project timelines
• Contribute to proposal development, RFP responses, and customer-facing technical documentation
• Track and report on pipeline status, counterparty technical requirements, and deal progress

Qualifications

• 8+ years of experience in a technical sales, sales engineering, or applications engineering role in power generation, fuel cells, electrical equipment, or adjacent industries
• Demonstrated track record selling complex power or energy infrastructure to data centers, hyperscalers, utilities, or large industrial customers
• Strong working knowledge of power systems, electrical equipment, or process/mechanical systems relevant to power plant delivery
• Ability to read and interpret technical drawings, single-line diagrams, and plant specifications
• Exceptional communication skills — equally effective in presenting to C-Suite and negotiating with a project engineer
• Experience supporting or co-owning commercial negotiations, term sheets, or PPAs
• High agency and comfort operating in an early-stage, resource-constrained environment
• Preferred: background in fuel cell systems, gas turbines, modular power, or other distributed generation technologies sold into data center or industrial markets
