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 for, use, and think about their mobile phones—and the privacy implications associated with them. 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 an Android Software Engineer at Cape, your mission is to build the definitive application for private mobile communication. We don’t just white-label an application and do the bare minimum for onboarding and collecting payment. The mobile application is the interface where users build trust with Cape and protect their digital lives. You will own the entire feature lifecycle—from architectural design to launch on both the Google Play Store and alternative, privacy-conscious app stores. Using Kotlin and Jetpack Compose, you will tackle some of the hardest technical challenges in security and cryptography in order to secure personal information (PII), account data, and even voice and SMS traffic. In our tight-knit engineering team, you won't just build features—you will ship the product that makes our promise of privacy a reality.

Here are some ways you'll make an impact

• Take ownership of the mobile product lifecycle — from conceptualization, through design and development, all the way to launch.
• Maintain high coding standards by developing guidelines, actively participating in code reviews, and fostering a culture of continuous improvement and knowledge sharing.
• Champion the security, performance, and stability of our applications by implementing and overseeing robust testing, monitoring, and release processes to guarantee a seamless, trustworthy user experience.
• Actively improve user workflows by collaborating with cross-functional teams, ensuring seamless experiences across product boundaries and a cohesive user journey.

What We Value

• Proven ability to learn continuously, work independently, and make decisions with minimal supervision.
• Experience brainstorming and iterating with product designers.
• A thoughtful, practical approach to problem-solving that considers tradeoffs and avoids over-engineering.
