What You'll Build & LeadAs 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: 01 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.
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.
