Job description

As Staff Software Engineer, you’ll be the technical backbone behind the 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 micro-services, ingestion, and LLM-driven systems.
• Mentor and multiply - up-level 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).
• 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

• Meaningful equity - real ownership in companies success.
• Unlimited PTO - we trust you to take the time you need.
• Tax free commuter and parking benefits
• Work directly with the founding team - your impact is immediate, visible, and career-defining.
