Quality Assurance Engineer

San Francisco, CA

Renting a home is the world's oldest subscription service. People spend thousands of dollars every month for an experience that is outdated, inconvenient, analog, impersonal, and leaves a lot to be desired. Latch is working to make every building better, and while we've methodically executed this mission since our founding with great success, we're just getting started.

Leveraging our knowledge from companies like Apple, BCG, and IDEO, we’ve rethought how people interact with space. Latch delivers a full-building operating system designed to help owners, residents, and third parties like guests, couriers, and service providers, seamlessly experience the modern building. We’ve done this by combining software, devices, and services into a holistic platform that makes spaces more efficient, enjoyable, and profitable.

The next chapter of the Latch story will be our most exciting yet, and we’re looking for more talented team members to help fuel our growth.

Latch is seeking a Quality Assurance Engineer to work with the Quality Engineering team.

You will be responsible for creating and performing testing on our firmware based products that residents interact with daily. You will own the entire device, testing for stability, responsiveness, security, and communication with connected products. You will work within highly cross-functional feature teams and collaborate closely with firmware, mobile, backend and hardware engineers. It is an exciting opportunity to be part of a growing team as we add value to our entire product family through more advanced electronics.

Smart access isn’t about locking doors, it’s about opening up new possibilities. Latch is the world’s first fully-integrated hardware and software system dedicated to bringing seamless access to every door in a modern building. We’re looking for the curious and the creative to join our team and help us continue to change the way we access our most valued spaces.
