How to apply 

We are accepting applications until Monday, November 3, 2025. Please submit an application with a resume and a cover letter by then

In your cover letter, we expect you to tell a little bit about yourself and what you can bring to Intree and this role in the future. You can also tell us about something you’ve done, something that’s relevant to the kind of work we do at Intree or simply something that excited you. Overall, be descriptive, but don’t write a novel (500 words or less).

We run a hybrid culture with a lot of asynchronous collaboration, so your ability to express yourself in writing is important and your cover letter serves as an example of your ability to do that.

You can expect to hear from us about the status of your application by the end of November. Please note that we’re unable to offer individual feedback during the screening process. Our small team simply doesn’t have the bandwidth to offer personalized feedback before the final round of interviews.
