Enterprise Account Executive

The role This is an unusual sales job, and we want to be upfront about that. Most enterprise AEs spend their careers selling horizontal SaaS. You'd be selling AI software to nuclear operators, which is a much smaller world, a much longer game, and (we think) a much more interesting one. We’re post-PMF and growing fast. We’re live at 70+ nuclear facilities across North America and the U.K., we have seven AI products in market, and demand is 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. You’d own a portfolio of net-new logos with North American nuclear operators, working deals from the first conversation through close. The people across the table are nuclear engineers, plant managers, and IT leaders who’ve been doing this for decades, and earning their trust is the best part of the job. What makes this job different A few things about the motion that are worth knowing up front: Pipeline is 100% inbound today. Referrals, conferences, the credibility our founders and customers carry. It’s a real flow and it’s growing, but it won’t be enough forever. We’re building a structured outbound motion as we scale, and you’ll help build it. 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. Nuclear engineers, plant managers, IT leaders with decades of experience. You don’t need to be a nuclear engineer to earn their respect. You need to know our products deeply and ask good questions. If you’ve sold complex software into regulated, technical industries, keep reading. What you’ll own Pipeline and prospecting. Build and maintain a pipeline of net-new nuclear operators. Today, pipeline is fully inbound through conferences, referrals, and partner relationships, and you’ll work that flow. You’ll also be expected to outbound on your own, without waiting for a formal strategy or playbook to be in place. Over time, you’ll help us build that structured outbound motion. Forecast honestly. Deal execution. Run multi-stakeholder enterprise sales cycles from discovery through procurement. Treat discovery as an ongoing practice, not a one-time stage: keep pressure-testing your assumptions in every meeting, because in a twelve-month cycle the customer’s reality, sponsors, and priorities will shift. Coordinate technical evaluations with Customer Success Engineers, navigate compliance and security reviews, and shepherd deals through long approval processes. Know when a deal is right for Nuclearn, and when to walk away. Customer relationships. Build trust with Director and VP-level stakeholders at nuclear operators, and earn your way to executive sponsors over time. In nuclear, access to power is granted, not taken. You won’t shortcut your way to a VP of Operations or a CNO by being persistent on email. You’ll get there by being useful, credible, and patient with the people around them, so that when the introduction happens, it happens because someone inside the account wanted to make it. Earn the right to be in the room when their next AI investment is being discussed. Industry fluency. Stay current on nuclear industry trends, regulatory shifts, new reactor builds, and how AI is evolving across adjacent industries. You’ll be smarter than the average AI vendor because of it. Cross-functional partnership. Work closely with Marketing on conference strategy. Partner with Customer Outcomes to make sure post-sale delivery matches what you sold. Bring customer signal back to Product. About you You’ve been in enterprise B2B sales for 8+ years, with real time spent selling complex software into regulated or technical industries: utilities, energy, defense, aerospace, industrials, healthcare, or somewhere similar. You’ve closed deals in the high six figures and beyond with buying committees that included engineers, IT, security, and procurement, and you’ve held the thread on deals that took six months or more. You’re patient and you’re organized, which sound like quiet traits but matter enormously here. You don’t spiral when a deal sits for a month. You stay close to it, you keep stakeholders engaged, and you forecast honestly even when honest is uncomfortable. Technical buyers tend to like you, not because you pretend to be one of them, but because you ask good questions and don’t waste their time. You use AI tools in your own work, so when a customer asks how Nuclearn fits into their workflows, you can actually have that conversation. You’re also up for building. Today our pipeline is fully inbound, but we expect AEs to outbound on their own without waiting for a formal strategy to be handed down. As we scale, we’ll need to layer on a more structured outbound motion, and we want someone who’s done that kind of work before and is excited to help us figure out what it looks like here. One more thing: we put a lot of weight on candor. You’ll tell a customer when Nuclearn isn’t the right fit. You’ll tell Phil when a deal you forecasted isn’t going to close. That’s rare in sales, and we mean it. Nice to have, not required: Experience selling into nuclear, utilities, or other energy markets Track record of building pipeline through conferences and field motion Background at a startup where the sales playbook was still being written How we work Our founders are nuclear engineers from Palo Verde who started Nuclearn to bring AI to an industry that genuinely needed it. The team between them now has 50+ years of nuclear experience, which is most of why customers trust us. The job of Sales is to extend that trust into commercial relationships, not to oversell or overpromise. Three of our company values show up most in this role. We care about Customer Wins, which means the deals worth closing are the ones where the customer is actually going to get value. We care about Candor, which means saying the hard thing with facts and without spin, even when it’s a deal you wanted to close. And we care about Ownership and Urgency, which means moving deals forward without waiting for permission. You’d be in our Phoenix HQ four days a week (Wednesdays remote) with Phil, the founders, the rest of Sales, and the engineering team. A few other things worth knowing: $300k+ uncapped OTE and equity participation Hybrid in our Phoenix HQ, ≥80% in-office, Wednesdays remote Expect 30 to 50% travel to customer sites and industry conferences U.S. citizenship or permanent residency required for DOE export compliance How we hire We try to keep this fast and respectful of your time. Our goal is first conversation to decision in three weeks or less. A 20-minute intro with Head of People or the Hiring Manager to trade context and figure out if there’s mutual fit A discovery and qualification exercise: a structured roleplay or deal walkthrough based on a real Nuclearn scenario A working session with the founders on a strategic account plan you’d build Reference conversations Nuclearn is an equal opportunity employer Nuclear has historically drawn from a narrow talent pool, and we think widening that aperture is part of how the industry moves forward. Nuclearn hires the best person for each role regardless of background, and we mean that as a practical commitment, not a legal line. Research consistently shows that women, people of color, and candidates from non-traditional backgrounds are less likely to apply unless they meet 100% of the qualifications. If you can do the work and the role excites you, please apply. The best hires we’ve made often surprised us. We don’t discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
