Customer Outcomes Jobs (NOW HIRING)

The role
At Nuclearn, a deal closing is the beginning of the work, not the end. If you're someone who finds the post-sale moment genuinely interesting, the messy hands-on work of turning a signature into outcomes, this is a role built for you.
Our AI platform is purpose-built for nuclear operations, currently seven products spanning condition reports, performance improvement, engineering workflows, and more. Every product a customer adopts comes with a specific, quantified outcome they're counting on, and our growth depends on delivering those outcomes consistently enough that customers want the next product, and the one after that. The Head of Customer Outcomes owns that whole journey.
Reporting to our CRO Phil Zeringue, you'll lead a team of five Customer Success Engineers (growing) and partner closely with Sales on expansion. You'll own the two metrics that drive Nuclearn's growth: time to value on the first product, and readiness to adopt the next one.
Why now
Nuclearn is post-PMF and scaling. We're live at 70+ nuclear facilities across North America and the U.K., our customer count is accelerating, and Net Revenue Retention is a core company goal. Customer Outcomes has been carried by our CRO alongside the rest of go-to-market, and that's not sustainable as we grow. This role exists to bring real structure to the function, scale the team thoughtfully, and turn customer success into the engine of our expansion strategy.
Our model is to start small, prove value, then expand. We can't grow an account until they've gotten what they already paid for. The faster you and your team deliver outcomes, the faster Nuclearn grows.
What you'll own
Implementation and deployment. Every new customer kickoff through go-live, on time and to standard. You'll build resource plans across concurrent projects, refine repeatable playbooks, and partner with Engineering when implementations need custom work.
Value realization. The transition from "platform is live" to "customer is getting what they paid for." Every sale includes an estimated outcome. You'll build the framework that makes those outcomes visible to both Nuclearn and the customer, and you'll close the gap when they diverge.
Team leadership. Lead, develop, and grow the CSE team. Set the bar for how CSEs engage with customers, manage deployments, and drive adoption. Hire the next several CSEs as we scale.
Customer relationships. Serve as the senior post-sale partner to Director and VP-level stakeholders at nuclear operators. Run business reviews focused on outcomes delivered, not features shipped. See risks before they escalate.
Expansion partnership. Work with Sales so that expansion conversations are grounded in proven value, not promises. Own the prioritization of customer feedback to Product.
First 90 days

• Meet every active customer and understand their deployment status, expected outcomes, and satisfaction level
• Assess the team: strengths, gaps, workload, development needs
• Build a consolidated resource plan across all active implementations
• Stand up a value realization tracking framework tied to each customer's purchase justification
• Identify the top three operational improvements that will most reduce time to value
• Establish your operating rhythm with Phil and the leadership team

About you
You've led implementation, customer success, or professional services teams in B2B SaaS or enterprise software for 5+ years, and you've directly managed teams of five or more. You've worked with Director and VP-level customers on accounts where the annual spend was meaningful and the deployment was complex.
You think in outcomes, not milestones. A successful go-live that doesn't produce the value the customer expected isn't a success to you; it's an incomplete project.
You're technical enough to understand integrations, data workflows, and platform configurations without having to do them yourself, and credible enough that your CSEs and your customers' engineers respect your judgment.
You're AI-fluent. You use AI tools in your work, you understand what's possible, and you can think alongside your team about where AI changes how customer success gets done. You don't need to build models, but you should be more comfortable with AI than the average professional.
You're comfortable with candor. You'll tell a customer the truth about why their outcome is lagging. You'll tell Sales when a deal isn't ready for expansion. You'll tell your team when something needs to change. We say the hard things here, with facts and without spin.
Nice to have, not required:

• Nuclear, defense, aerospace, or other regulated-industry experience where deployment complexity is high
• Experience in a high-growth SaaS company where the playbook was still being written
• Familiarity with land-and-expand models where CS directly drives revenue

You'll be in your element if...
We try to be honest about where people thrive here, because that saves everyone time. Some patterns we've seen:

• You're comfortable building without a playbook. A lot of what you'll do here, you'll figure out as you go. We're past product-market fit, but we're still building most of the systems around it.
• You're energized by fast cadence. The work moves fast. Customers are growing. Priorities shift. People who do well here lean into that pace rather than waiting for it to settle.
• You bring decisions, not just questions. Our managers expect you to come with "Here's what I'm going to do, unless you tell me otherwise," not "What should I do?"
• You want candid feedback. We tell each other the hard things, with facts and without spin. People who do well here find this energizing, not uncomfortable.
• You like reaching across function lines. Small team means everyone wears multiple hats. The boundary of your role is whatever the work needs, and that's a feature, not a bug.

How we'll know you're winning
Time to value is the primary metric, the duration from contract signed to outcomes realized. Everything else supports it: customer retention and expansion readiness, on-time implementation, executive-level customer satisfaction, and the performance and retention of the CSE team.
How we work
Our founders are nuclear engineers from Palo Verde who built Nuclearn to bring AI to an industry that needed it, and to do it in a way that actually makes operations better, safer, and smarter. Our team now has 50+ years of combined nuclear experience between them.
We're a values-driven company. Six values shape how we work, and two will be especially visible in this role:
Customer Wins. Their win is our win. This role exists because we believe customer outcomes are a Nuclearn obsession, not a department.
Ownership and Urgency. See it, own it, fix it. We don't wait for permission to do the right thing, and we don't pass problems sideways.
We're based in Phoenix and we're building a real HQ here. You'll be in the office with the founders, the engineering team, and the rest of Go-to-Market four days a week (Wednesdays remote). For senior leaders who want proximity to the people building the product and the customers who use it, this is a feature.
A few practical notes

• Full-time, salaried, with equity participation
• Hybrid in our Phoenix HQ (≥80% in-office, Wednesdays remote)
• U.S. citizenship or permanent residency required for DOE export compliance

How we hire
Fast, respectful, and practical. Our goal is first conversation to decision in three weeks or less.

1. 20-minute intro with Phil to trade context and assess mutual fit
2. Practical work sample (60-90 min; a real task in our stack)
3. Team meet and working session focused on collaboration and judgment
4. Final conversation with the founder

Nuclearn is an equal opportunity employer
Nuclear is an industry that 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 shows that women, people of color, and candidates from non-traditional backgrounds are less likely to apply for roles unless they meet 100% of the qualifications. If you can do the work and the role excites you, apply - even if your path here doesn't look like the one we described. 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.
