AI policy Notice:
We want you to get the chance to know us in the interview process and for us to learn as much as we can about you, too. To make this possible and to ensure fairness for all our candidates, we have a no-exceptions policy on AI usage and augmentation during interviews. While we are an AI first company, this does mean we prohibit any AI tooling during the interview process unless otherwise explicitly allowed (such as large language models, code suggestion software, or AI assistants) to generate, refine, or suggest answers, solutions, or code, regardless of the format (written, spoken, or coded). We want to get to know you, your experiences, and qualifications genuinely and directly and the best way to do this is to keep it just between us.

To keep the interview fair for all, we reserve the right to ask follow-up questions or request you to clarify or elaborate on your solutions without the aid of external tools to validate that the answers provided genuinely reflect your own skills and experience. Violation of this code of conduct will result in the immediate termination of your candidacy.

Background Check Required. As part of our employment process, a background check is required. This may include a review of your credit history, criminal records, and employment verification, conducted in compliance with the Fair Credit Reporting Act (FCRA).
