We are AI Native We use AI coding tools as a professional standard on this team. Here's what that means in practice: Daily use: You use AI coding assistants (we support Claude Code, Cursor, and GitHub Copilot) for real, substantive tasks: analysis, coding, refactoring, testing, navigating codebases, and documentation. Not just research or autocomplete. Judgment and ownership: AI-generated code gets the same review you'd give any PR. You are accountable for everything you ship. Velocity: We expect senior engineers who use AI well to operate with meaningful leverage - doing more with the same time, taking on problems that would otherwise require a larger team. Team leadership: You share what works. You automate prompting strategies that others can build on and help teammates earlier in their AI workflow adoption get up to speed. Continuous learning: The tooling is changing fast. You stay current and bring recommendations to the team when something would meaningfully improve how we work. Undisclosed use of AI not previously discussed with or approved by your Recruiter may impact your candidacy.
