Windows Phone 8 just came out in November, but it's not a huge shock to learn that Microsoft is already working on the next major version of its mobile OS. On Wednesday, a job recruiter for the company, Ashley Zenner, posted up a note on her Twitter account.
The Microsoft Careers link that was placed inside Zenner's Twitter post is for a Senior Software Engineer Post, but oddly the job description says nothing about working with the Unified Extensible Firmware Interface mentioned in her post. Here's what it does say: "The role will expose you to multiple subsystems across Windows Phone and requires an ability to ramp to new hardware and software technologies quickly."
So the big question is, "How does this new job involve UEFI?" It's possible that this position at Microsoft could be for improving security for the next version of Windows Phone, or perhaps a way to boost performance or maybe something that is totally new and unexpected. In any case, it's likely that we won't learn about this new mystery tech for months, or even years.
