Staff RF Systems Engineer

We’re embracing a hybrid work model that enables our teams to split their time between office and home. Hybrid for us means we expect our teams to come together in our state‑of‑the‑art office on two core days, typically Tuesday and Wednesday, to work together in person, while teams can choose where they work for the remainder of the week.

We’re growing and thriving. We need smart, talented, and humble people who share our values to join us as we disrupt the home security space and pursue our mission of keeping Every Home Secure.
