# Staff Software Engineer - Company: [Moonshot Ai]() - Location: New York City - Team: Engineering - Employment type: Full Time - Salary: $190K – $260K - Posted: January 23, 2026 ## Job description ## **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 compensation** * **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. * **Tax free commuter and parking benefits** * **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. * **Free One Medical** Membership * **401k** ## Apply [Apply on Moonshot Ai]() Canonical job page:
