- Identify and resolve performance bottlenecks, bugs, and edge cases in production environments.

- Participate in code reviews, mentor engineers, and raise the bar on code quality and best practices.

- Proactively identify technical debt and drive improvements before they become blockers.

- You are highly proficient in Python and at least one modern framework (Django, FastAPI, or Flask), and you take ownership of what you build—from design through production.

- You have strong experience building and consuming APIs, and understand how systems communicate, fail, and scale in real-world environments.

- You are comfortable with both SQL and NoSQL databases, and can analyze data, write efficient queries, and reason about performance.
