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 & Lead

As our Staff Software Engineer, you’ll be the technical backbone behind Moonshot’s evolution engine - designing scalable systems, guiding engineering strategy, and mentoring the builders around you.
You’ll balance hands-on depth with architectural altitude, turning vision into technical reality.

You will:

  • Work at the forefront of generative AI and agentic flows - build systems that let AI autonomously reason, experiment, and deploy real changes to the web.

  • Architect the next generation of Moonshot’s experiment engine - scalable, observable, fault-tolerant, built for millions of daily events.

  • Design and evolve our backend infrastructure across Python (Flask-RestX), serverless AWS, and data pipelines (ClickHouse, Postgres, Kinesis, Firehose, S3).

  • Drive technical strategy - define our engineering principles, evolve architecture across microservices, ingestion, and LLM-driven systems.

  • Mentor and multiply - uplevel senior and mid-level engineers through code reviews, pairing, and design docs.

  • Collaborate cross-functionally - work with AI, product, and data science to translate business needs into resilient systems.

  • Prototype and push boundaries - bring ideas from concept to production fast, balancing experimentation and rigor.

  • Raise the bar on performance, security, and reliability as we scale toward SOC 2 and enterprise clients.

This isn’t a people-management role - it’s technical leadership at its purest form: deep design, high leverage, and full ownership.

Who We’re Looking For
  • 8+ years of experience designing and shipping production systems at scale (bonus: 0→1 or startup environment).

  • Strong expertise in Python, AWS, and JavaScript - you’re comfortable owning both backend and frontend architecture.

  • Proven ability to design distributed systems (event-driven, microservices, or data-heavy architectures).

  • You’ve been a technical lead or staff engineer - mentoring peers, reviewing designs, and setting engineering standards.

  • Bias toward action and clarity - you simplify, document, and deliver.

  • Deep curiosity about AI and experimentation - you love systems that learn and adapt.

  • Bonus: experience with ClickHouse, LLMs in production, or ecommerce/analytics infrastructure.

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.
