Enterprise Account Executive

Nuclearn brings modern AI to one of the most demanding industries in the world: nuclear power. The work that keeps a plant running safely sits under mountains of procedures, regulatory documentation, and engineering review, and most of it is still done by hand. We build AI made for the realities of nuclear operations, not adapted from generic tools, so the engineers and operators who keep plants running can spend their time where it counts.

We're out to rebuild how an entire industry runs, not tinker at its edges.

This matters more now than ever. Nuclear is having its biggest moment in a generation, and we're building at the center of it. As the world turns back to nuclear for clean, reliable power, operators have to do more without growing their experienced workforce at the same pace. Our aim reaches past any one tool: we want to partner with utilities across the industry to make nuclear faster to run and safer to scale.

We're not just bringing AI to nuclear, we're challenging the idea that a safety‑first industry has to be a slow one. We win as one team, we make every dollar and hour count, and we treat our customers' wins as our own.

Enterprise Account Executives at Nuclearn sell AI software into nuclear plants. It's one of the more interesting enterprise sales jobs in tech right now, if you want a real product and a market that matters.

We're post‑PMF and growing fast, with seven AI products in market and demand accelerating as the U.S. expands nuclear capacity for the first time in decades. We need more senior AE capacity to keep up with what's in front of us.

Reporting to CRO Phil Zeringue, you'll own a portfolio of net‑new logos with North American nuclear operators and work each deal from first conversation through close. It's an individual quota‑carrying role, measured on net‑new logos and the multi‑year platform commitments behind them. Your job is to extend the credibility our founders and customers have already built, not to oversell it.

A few things about the motion worth knowing up front:

• Pipeline is 100% inbound today. Referrals, conferences, and the credibility our founders and customers carry. It's a real flow and it's growing, but it won't be enough forever, and you'll help build the structured outbound motion as we scale.

• Cycles run six to eighteen months. The deals are worth it. Every close is a multi‑year platform commitment with a nuclear operator.

• You're selling to deep technical experts. You don't need to be a nuclear engineer to earn their respect. You need to know our products deeply and ask good questions.

• Access to power is granted, not taken. You won't email your way to a VP of Operations or a CNO. You earn the introduction by being useful, credible, and patient with the people around them, until someone inside the account wants to make it.

If you've spent your career on transactional, high‑volume inbound, this won't be the right fit. If you've sold complex software into regulated, technical industries, keep reading.

• Pipeline and prospecting. Build and own a pipeline of net‑new nuclear operators, working the inbound flow and prospecting on your own without waiting for a formal playbook. Forecast honestly.

• Deal execution. Run multi‑stakeholder cycles from discovery through procurement, treating discovery as ongoing because sponsors and priorities shift over a year‑long deal. Coordinate technical evaluations with Customer Success Engineers, clear compliance and security reviews, and know when to walk away.

• Customer relationships. Build relationships with Director and VP‑level stakeholders and earn your way to executive sponsors over time, so you're in the room when their next AI investment is discussed.

• Industry fluency. Stay current on nuclear trends, regulatory shifts, new reactor builds, and how AI is moving in adjacent industries. You'll be smarter than the average AI vendor for it.

• Cross‑functional partnership. Work with Marketing on conference strategy, partner with Customer Outcomes so delivery matches what you sold, and bring customer signal back to Product.
