Build basic prototypes, test them with users, gather feedback, and iterate quickly.

Use AI coding tools (Cursor, Copilot, Claude Code, or similar) as a core part of daily workflow to maximize individual throughput and code quality.

Maintain existing systems, address operational issues, and contribute to infrastructure health.

You will be a great fit if...

You are proficient in Ruby/Rails and TypeScript/React, or a have proven ability to master comparable stacks quickly.

You actively use of AI coding assistants daily , paired with the technical judgment to verify and refine their output.
