RF Systems Engineer

We’re a high-tech home security company that’s passionate about protecting the life you’ve built and our mission of keeping Every Home Secure. We’ve created a culture that cares just as deeply about the career you’re building.

Hybrid work model:
Our teams split time between the state‑of‑the‑art office and home. We expect our teams to collaborate in person on two core days, typically Tuesday and Wednesday, and choose remote work for the rest of the week.

As a Staff RF Systems Engineer, you will be a key technical leader responsible for RF product development and validation  will help design and build Simpli Safe’s RF capabilities with the goal of achieving best‑in‑class wireless connectivity. You will work closely with engineering teams to choose chipsets, optimize mechanical and electrical designs for RF performance, and lead our ODM design partners through design, test, and qualification of new products.
