Software Engineer, Infrastructure

About Cape: Cape is America’s privacy-first mobile carrier. Our mission is to be a force for good in global wireless. Founded in 2022, we believe privacy is a fundamental right, not a luxury. We built America’s most private and secure mobile carrier from the ground up, addressing critical vulnerabilities in legacy cellular infrastructure that track movements, monitor connections, and sell personal data. Today, Cape serves consumers, businesses, and government agencies, providing a secure network with unmatched privacy and security features. We closed our Series C in March 2026 and are scaling rapidly to give people control over their personal information.
