## About the Role

* High agency: you see a problem and think "this needs to work, I'll figure out how." You're comfortable defining requirements yourself, making judgment calls and owning the result.
 * AI-native engineering: you use tools like Claude and other coding agents heavily and effectively in your day-to-day work, well beyond occasional autocomplete.
 * Strong generalist ability: you have solid experience with Python and PostgreSQL and can contribute across backend, data, infrastructure and web application layers with React.
 * Proven builder: you have taken real systems from ambiguity to production, ideally at an early-stage startup, an AI-native company, a research-heavy environment or a 0-to-1 team inside a larger tech company.
 * Customer orientation: you care about the practical impact of what you build, not just technical novelty.
