Why Moonshot AI?

Imagine websites that rebuild themselves on autopilot to sell more, convert better, and grow faster.
At Moonshot AI, we’re making that happen — merging generative AI, large-scale data pipelines, and experimentation into a self-evolving web.

We’re a well-funded, very early-stage startup with a massive vision. Joining now means you’re not just an employee — you’re helping set the technical and cultural DNA of the company. If you’ve ever wanted the autonomy of a founder with the backing of top-tier investors, this is it.

What You’ll Build & Achieve

You’ll touch every part of the stack and learn how to build systems that scale to millions of users. This isn’t a “ticket taker” job — you’ll be writing real production code from day one.

  • Build and ship features across our frontend dashboards and backend APIs.

  • Work with massive data streams that track millions of web events daily.

  • Help train and integrate AI models that suggest and test website improvements.

  • Collaborate with senior engineers to design scalable systems and best practices.

  • Prototype fast, test constantly, and learn how to turn ideas into shipped features in days.

  • This role is about learning through impact — the more you contribute, the faster you’ll grow.

Who We’re Looking For
  • 0–3 years of experience building web applications.

  • Comfortable with Python, JavaScript, and modern frameworks (React, Node, Flask, etc.).

  • Strong computer science fundamentals (or equivalent practical experience).

  • Excited about AI, experimentation, and startups.

  • Hungry to learn, unafraid to ask questions, and eager to ship.

Bonus Points:
  • Startup experience.

  • Experience playing with LLMs, ML models, or data pipelines.

  • A non-trivial portfolio, GitHub, or side projects you’re proud of.

At Moonshot, culture isn’t fluff — it’s how we win
  • Curiosity & Growth → We challenge assumptions, ask big questions, and push for mastery.

  • Low Ego → No ivory towers — everyone gets their hands dirty.

  • Ownership → You own outcomes, not just outputs. Shipping is step one; impact is the goal.

  • Trust → Radical transparency and accountability, even when it’s hard.

  • Agility → We move fast, test faster, and aren’t afraid to pivot.

  • This Is Your Company → Ideas fuel breakthroughs. We’re all builders here.

  • Enjoy the Ride → Startups are a rollercoaster — we create good vibes and celebrate wins together.

What We Offer
  • Competitive salary

  • Meaningful equity — real ownership in Moonshot AI’s success.

  • Full health coverage (medical, dental, vision) for you + your family.

  • Unlimited PTO — we trust you to take the time you need.

  • Office-first culture (4 days/week) — Midtown Manhattan, in the middle of it all.

  • Work directly with the founding team — your impact is immediate, visible, and career-defining.

  • Backed by top investors in NYC, SF, and TLV.
