"The PC Compatibility Tester will evaluate PC hardware-specific features and ensure various systems work together across multiple PC configurations to provide a great experience," the post reads. A required skill is that the applicant be "experienced and comfortable with building PCs from scratch."
As far as we know, Bungie is only working on one game: Destiny, with plans for a 10-year life cycle alongside publisher Activision. Neither company has ever confirmed active development of a Windows PC version of Destiny.
Eric Hirshberg, CEO of Activision Publishing, told Polygon during E3 2014 — three months before Destiny launched — that a PC version of the game was "something we're talking about and looking at very carefully." Earlier that year, Bungie writer Eric Osborne said, "We have a lot of people who play on PCs. We have a lot of appetite to build that experience."
Some of Bungie's other active job listings mention PC, though only in passing; none are as PC-focused as the compatibility tester position. But that job posting also describes a compatibility tester at Bungie as being "grouped into teams, responsible for ensuring that an area of the game is ready to ship." Unless Bungie has been secretly working on a PC version of Destiny, this could mean that the role is for something besides Destiny.
Bungie has a long history of making computer games, going back to the 1990s series Marathon and Myth on Mac and PC. But the company has not released a game on PC since Halo 2, the PC port of which was released in 2007, two and a half years after the game debuted on the original Xbox.
We've reached out to Activision and Bungie for comment, and will update this article with any information we receive. Bungie is currently working on Destiny's third expansion, The Taken King, which launches Sept. 15.
