The Airbnb Talent Directory

The past few months have been hard for all of us, but it has been inspiring to see everyone, especially the Airbnb community, support each other during an unprecedented time. Our CEO, Brian Chesky, recently announced the departure of nearly 1,900 employees. Among these employees are incredibly talented Engineers and Data Scientists who have contributed to Airbnb in uncountable ways. To support our teammates departing Airbnb, we launched the Alumni Talent Directory, an opt-in directory which lists valued employees and contingent workers who have recently departed Airbnb. If you’re currently hiring or looking for incredible talent, the Talent Directory is full of amazing Engineers and Data Scientists, among others. We hope we can connect these individuals with new opportunities. It’s been an honor to work with such a talented team committed to our mission of belonging, and we’re confident any company would be lucky to have them. We’d also like to thank the cross-functional team that created the site in an extremely short period of time. We are all grateful for their hard work: Chris Arrington, Gina Groom, Noor Malik, Derek Southard, Parag Hardas, Robin Foyle, Mike Fowler, Christian Williams, Megan Gebhart, Alex Cheng, Steve Rafferty, Sonia Yang, Andy Tran, Angela Wu, Linsey Jackson, James Deslonde, Kelly Coldwell, as well as Joe Gebbia for inspiring the idea.
