Lead Mobile Engineer

About Cape

Cape is America's privacy-first mobile carrier. Our mission is to be a force for good in global wireless. Cape was founded in 2022 by people who believe privacy is a fundamental right, not a luxury to be traded away. Our journey began when our founder recognized a critical vulnerability in our modern world: everyone relies on the same stagnant cellular infrastructure and legacy systems that track our every movement, monitor and profile our connections, and lose and sell our personal data. Instead of accepting the status quo, we decided to fix it. National security professionals, journalists, parents, and everyone in between can stay connected and have privacy. We didn't just build a layer on top of old tech; we built America's most private and secure mobile carrier from the ground up. By building our own network from scratch, we are able to design and build a suite of privacy and security features that no other carrier on the planet can offer. Today, Cape provides our secure network to consumers, businesses, and government agencies alike. We closed our Series C in March 2026, and we are scaling rapidly, with the goal of giving people back control of their most personal information.

The Team

At Cape, we are the architects of a privacy-centric movement that is just getting started. We are relentless builders, constantly innovating at the edge of what's possible in telecommunications. We operate on a foundation of high trust and high expectations. As a member of our team, you will collaborate with world-class engineers, architects, and visionaries, and work across organizational lines to solve 'impossible' problems and deliver mission-critical results for our users every single day.

The Role

Cape's platform gives customers end-to-end control of their digital identity, optimizing for resiliency, privacy, and security at every turn. We're transforming how customers sign up, use, and think about their mobile phones and the privacy implications associated with it. Customers are protected at every level of the communications stack – from the mobile device, through infrastructure, and to the core of the network itself. As a Lead Software Engineer on the mobile team at Cape, you will architect the future of private mobile communication by leading and scaling our mobile engineering team. You will lead the charge on building our secure iOS and Android suite of products, translating our privacy-first mission into a best in class user experience and functionality. We don't just whitelabel an application and do the bare minimum for onboarding and collecting payment, but instead we're building natively from the ground up to solve some of the hardest technical challenges in security and cryptography in order to secure personal information (PII), account data, and even voice & SMS traffic. You will cultivate a high-performing, engaged team, providing technical mentorship and people-focused leadership needed to deliver outcomes. In close partnership with Product and other Engineering leaders, you will define and execute our mobile strategy, foster a culture of technical excellence, and build the capabilities required to protect our users in a constantly evolving digital landscape. Your day-to-day will change, but everything you work on has a high impact. One day you could be pushing to deliver a new capability to prevent targeting of soldiers on the battlefield, the next you could be architecting a new system to prevent financial fraud via SIM swaps for everyday citizens.

How You'll Make an Impact

• Build the mobile telecommunications applications of the future to provide the most resilient, private, and secure cellular connectivity.
• Maintain high coding standards through the development of guidelines, active participation in code reviews, and fostering a culture of technical excellence.
