Apply Now ✨

The Company

Cape was founded in early 2022 by Palantir and Anduril alums with deep expertise in privacy and national security. While running Palantir’s US national security business, our CEO became passionate about privacy and security on mobile devices. Our mission is to be a force for good in global wireless.

At Cape, we are not just another cellular service provider; we are the architects of a privacy-centric movement that starts with the devices in your pocket. We are building a cellular network that helps citizens, including those responsible for our nation’s security, regain control of their own data.

We believe that where we are, where we go, and whom we are with are among our most personal information and should be kept private. Privacy is not something you achieve by limiting yourself or by doing less, it is a set of features to be built so you can do more. We have raised money from Andreessen Horowitz and other top-tier VCs, and are excited to grow the team.

The Team

We are relentless builders, constantly innovating and pushing the boundaries of what a telco can do. At Cape we trust our teammates to be great, and expect them to make profound impact. As a member of our team, you will collaborate with some of the smartest engineers, architects, and builders anywhere, working across organizational lines to deliver for our customers, every time.

The Role

We are seeking a seasoned Security Engineer with a specialization in detection and response to join our team. As a strategic partner, you will be responsible for designing, implementing, and maintaining security measures that comply with regulatory standards, enhance internal processes, and minimize data security risks. Through developing ongoing security strategies and technologies, you will support the organization's business objectives and daily operations.
