Senior Embedded Android Engineer

  • San Francisco Pier 33 - Alcatraz Island, San Francisco, CA, USA
  • Full-time

Company Description

Let your dog walker into your apartment while you’re at the office. Or grant your in-laws access to the building’s gym while you’re sunning on a beach. It’ll be possible at new projects by some of the biggest U.S. builders.

Toll Brothers Inc., Brookfield Property Partners LP, RXR Realty and Related Group of Florida are among developers incorporating smart-access technology from this leader in door access in selected upcoming condo and rental projects. 

Users can grant access to guests and service providers, like dog walkers and cleaners, by providing them temporary entry codes. A wide-angle camera embedded in the hardware at each doorway will create a visual record of every interaction by a non-resident -- all of it viewable through the Latch app on the resident’s phone.
