Last Energy is a nuclear energy company that designs, builds, owns, and operates small modular reactors (SMRs) for industrial and commercial customers. The company's flagship product, the PWR-20, is a 20 MWe pressurized water reactor that is fully modular and factory-produced, enabling faster and more cost-effective deployment than traditional nuclear power plants. Last Energy serves as a behind-the-meter independent power producer, supplying reliable baseload electricity to energy-intensive industries including data centers, metals production, food and beverage, pulp and paper, chemicals, and cement manufacturing.
The company's mission centers on making nuclear power radically simpler and more accessible by removing the burden of development, financing, and operations from customers through a power purchase agreement model. This approach aligns nuclear energy deployment with the urgent need for resilient, low-carbon power, particularly as demand from AI infrastructure and industrial growth accelerates. Last Energy's use of proven reactor technology combined with proprietary steel containment systems is designed to streamline licensing and reduce construction timelines.
Last Energy represents a new generation of nuclear developers focused on decarbonizing hard-to-abate industrial sectors with firm, emissions-free power. By standardizing and modularizing the entire plant through factory manufacturing, the company aims to bring predictable costs and schedules to a sector historically challenged by both, positioning SMRs as a practical climate solution at commercial scale.
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
