A note on AI ✨ Use it. We'd think less of you if you didn't. We see AI as an opportunity to improve how we work, and we're interested in people who are already experimenting with it in practical ways. Write the first draft of your application yourself, then use AI to sharpen it rather than replace your thinking. You can also expect to use AI during at least one stage of the interview process. We're interested in how you work with it, not whether you can work without it. The perks?
