This mini-series by Alex Garland (28 Days Later writer and Ex Machina director) is about a tech company like Google that has a building that only select developers (devs) work in. Sergei is one of the lucky ones that get the call but he disappears after his first day. His girlfriend, who works for the same company, tries to find out what happened to him, first by uncovering well-kept dark secrets about that building. If you liked Mr. Robot or Ex Machina, you will love this. And a surprise bonus: Nick Offerman plays the CEO of the company, in a great serious role.
