TLDR
Leads technical sales activities for a micro-modular nuclear plant pipeline, translating complex plant specs into commercial terms and coordinating cross-functional teams.
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.
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 escalate 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
