## About the role

We are looking for an exceptional Principal or Staff-level engineer who has fundamentally changed how they build software because of AI. This is not a traditional software engineering role with an AI assistant bolted on. We want someone who uses AI agents, especially Claude Code, to independently take well-defined product initiatives from business requirements to secure, tested, production-ready software.

## What they're looking for

- Significant experience operating at the Staff, Principal, or equivalent engineering level, with 8+ years of professional software development experience
- A track record of independently delivering complex, production software in partnership with Product and Design teams
- Expert-level experience with Claude Code. This is a mandatory requirement. You must be able to demonstrate substantial product development with Claude Code — not merely autocomplete, isolated code generation, or simple prompting
- Experience coordinating multiple AI agents or development sessions in parallel, with a deep understanding of agent context, skills, sub-agents, tool use, planning, verification, and orchestration
- Production experience with both a dynamic language ecosystem and a strongly-typed one. Production TypeScript/Node.js experience is required
- Experience with relational databases (PostgreSQL, MySQL) and document/NoSQL databases. MongoDB experience is required
