Magic Leap, the ultra-secretive mixed reality startup worth $4.5 billion, is gearing up to test a product outside the lab, according to a job posting on GlassDoor.

The post for a field engineer, published on Dec. 4, indicates Magic Leap’s “mixed reality” headsets need more data in a variety of environments, presumably so they’ll be able to function correctly in different settings. From the post:

This position involves collecting data with Magic Leap devices in real world locations. Work will entail setting up and using high precision equipment to capture both environments and user behavior in home settings. Applicants will be based at Magic Leap Headquarters in Plantation, and drive with equipment to nearby locations for data collection.

It’s difficult to discern much more from the posting than that the company has built “devices” capable of capturing data from the world around it, and that the devices probably run Linux (“Some experience working with Linux command line tools is a plus”). It’s unclear whether these “devices” are the company’s planned mixed reality headsets themselves, or some sort of special camera that captures environments the same way a mixed reality headset would.

Magic Leap is rumored to be unveiling their product in 2017 (although the company has said specifically it won’t happen at CES 2017 in January). However, if you live in the Plantation, Florida area you might just get a sneak peak. (If you do, send pics.)

A Magic Leap spokesperson declined to comment.
