Job description

Founding Fullstack Engineer (3-8 Years Experience)
New York City (5 days on-site) • Top of market + equity + benefits
TL;DR: Build the product that nuclear operators depend on daily. Own features end-to-end. High-leverage IC role with founding-level impact.
The Mission
Everstar builds the intelligence layer that makes nuclear power actually deployable-collapsing regulatory workflows from months to days. Gordian already powers engineering and compliance work for utilities, advanced reactor companies, and hyperscalers. We pair deep nuclear domain expertise with world-class product execution and move with startup speed.
Now we need a Founding Fullstack Engineer to turn complex engineering and regulatory workflows into intuitive, production-grade software.
You'll be joining the Apollo Team of Nuclear. You'll build alongside engineers from Tesla, SpaceX, Lockheed Martin, Google, and Microsoft. You'll learn from nuclear and national security experts who cut their teeth at the Nuclear Regulatory Commission, CIA, and NuScale.
The Role (reporting to the CEO)
Not a contractor. Not a feature factory. This is an ownership-first role.
You'll architect and ship product features end-to-end-from database design to API contracts to pixel-perfect UI. Think 60% frontend / 40% backend with the autonomy to make technical decisions and the accountability to own outcomes.
Most weeks you'll be designing new flows, implementing features, and refactoring systems-then immediately seeing customers use what you shipped.
You will:
  • Build user-facing features: translate messy regulatory workflows into clean, intuitive UI/UX that nuclear professionals actually want to use.
  • Own the stack: design APIs, optimize queries, implement frontend interactions, and debug production issues-whatever it takes to ship.
  • Set product standards: you're early enough to define how we think about code quality, design systems, testing, and the entire product development process.
  • Collaborate with domain experts: work directly with nuclear SMEs and AI engineers to understand complex requirements and ship solutions that actually solve problems.
  • Balance speed and craft: know when to optimize for polish and when to ship fast; make tradeoffs consciously and communicate them clearly.
  • Lead by example: as the team scales, you'll mentor other engineers-but first, you'll prove the playbook yourself.

A sample week: ship new document collaboration feature; refactor search results to improve load time by 40%; pair with AI engineer to integrate new model output; design mockups for compliance workflow redesign; debug production issue reported by customer; review two PRs.
What You've Done
  • 3-8 years fullstack experience building production web apps. You've shipped features users depend on daily and owned parts of the product top to bottom.
  • Strong frontend chops: expert-level TypeScript/React, deep understanding of modern frontend patterns, and genuine care about UI/UX details.
  • Solid backend fundamentals: comfortable with APIs, databases, auth, and backend architecture. You can debug performance issues and design scalable systems.
  • Product sense: you think about business outcomes, not just code. You ask "why are we building this?" and "how will users actually use it?"
  • Ownership DNA: you've led projects, made technical decisions, and been accountable for outcomes-not just tickets.
  • Bonus points: experience with technical SaaS, regulated industries, or you have strong design taste and can mockup flows in Figma.

No nuclear background required-only the drive to build products that matter.
Who You're Building For
Our customers are the critical operators in the nuclear industry-the professionals keeping 20% of U.S. electricity safe and reliable. They're:
  • Overworked and under-resourced: carrying the weight of the grid on their backs
  • Navigating byzantine regulations: decades-old processes that slow everything down
  • Desperate for modern tools: they deserve software as good as what consumer tech gets

The products you build will help them:
  • Onboard and train faster-reducing time-to-productivity from months to weeks
  • Execute safety-critical workflows-with confidence, speed, and audit trails
  • Keep vital infrastructure safe-because "good enough" isn't good enough in nuclear

This is meaningful work in the truest sense-you're giving frontline professionals the tools they need to secure the energy backbone of our society.
What's at Stake
  • If we succeed: Operators get world-class tools, nuclear scales to meet exploding energy demand, and we power the AI era with clean energy. The products you build directly accelerate deployment.
  • If we fail: Nuclear remains stuck in red tape, operators stay overworked without modern tools, and humanity misses a once-in-a-generation chance to solve climate.

What Success Looks Like (90 days)
  • Shipped ≥3 major features to production that customers actively use.
  • Product quality standards you set (testing, code review, design patterns) are now team norms.
  • Customer-reported bugs down ≥50% because you improved monitoring, testing, or reliability.
  • You've owned a critical system-search, document viewer, compliance workflow, or core infrastructure-that other engineers depend on.
  • At least one product decision you made (architecture, UX flow, or technical tradeoff) is now the way we do things at Everstar.

Growth Path
Strong founding fullstack engineers typically grow into Head of Engineering, Product Lead, or CTO-track roles as the company scales.
First, you'll prove you can own product features and set the bar for execution.
Why Everstar
  • Work with the best: high-caliber, wartime team that builds things that scale
  • Build shit that matters: products that keep the grid safe and accelerate the clean energy future
  • Top of market base + meaningful equity in a fast-growing company; standard benefits (health/dental/vision, FSA, wellness stipend)
  • IRL in NYC (midtown/Bryant Park). Occasional travel to nuclear power plants and conferences.

How to Apply (show, don't tell)
Submit application with:
  1. Resume AND LinkedIn profile
  2. Portfolio or GitHub: show us something you built (side project, open-source work, or product you're proud of)
  3. 200 words: "What excites you most about building products for nuclear deployment?"
  4. 150 words: "Describe a product/feature you owned end-to-end. What were the hardest product tradeoffs and how did you resolve them?"

We respond to strong submissions within one week.
Let's build.
