Android Engineer

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.

We are relentless builders, constantly pushing the boundaries of what's possible and bringing to life ideas that have never before existed. Innovation is at the core of everything we do. At Cape, we trust our team to deliver greatness and empower them to make a profound impact. As a member of our team, you will collaborate seamlessly with our diverse group of talented engineers and other team members, enjoying dynamic interactions with colleagues from across the organization.

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.

Your day-to-day will vary, but everything you work on will have a high impact. One day, you could be delivering a new capability to prevent targeting of soldiers on the battlefield; the next, you could be architecting a system to prevent financial fraud via SIM swaps for everyday citizens.

• 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.

• 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.

• Comfort working in a constantly evolving environment with dynamic objectives and frequent iteration with users.

• Ability to collaborate effectively with both technical and non-technical teammates, and an understanding of how technical decisions impact users.

• Understanding of cryptographic systems and how to design privacy-conscious solutions.

• Ability to learn new technologies and concepts, even without prior in-depth experience.

• Active U.S. security clearance—or eligibility and willingness to obtain one—is beneficial, but not required.

• 1+ years of Android software development experience.

• Background in Computer Science, Mathematics, Software Engineering, Physics, or a related field.

• Proficiency in Kotlin and a strong foundational understanding of the Android ecosystem (architecture, app lifecycle, concurrency, etc.).

• Professional experience with Jetpack Compose is preferred, but a deep appreciation for building modern user interfaces is essential.

• Strong written and verbal communication skills, with the ability to iterate quickly with teammates, incorporate feedback, and maintain a high bar for quality.

• Experience with Android concurrency and storage frameworks such as Coroutines, Room, and DataStore.

• Familiarity with privacy-focused Android OSs.

• Knowledge of cryptography, trusted execution environments and StrongBox, or cellular technologies (eSIM, 4G, 5G).

• We are builders, and we choose to spend our time building things that matter. Many of our people have backgrounds in Defense Tech as well as the defense and intelligence community. We build to win.

• We hire excellent people, give them outsized responsibility, and trust them to execute at a high level. Everyone here has a track record of solving hard problems throughout their careers.

• We believe that personal privacy and national security interests are not inherently at odds, and can be reconciled via strong technology.

• We believe that companies exist to build awesome things and take care of their people. Our benefits reflect that– top-tier health care, 401(k) matching, and a generous vacation policy (that we actually use).

• We hire candidates of any race, color, ancestry, religion, sex, national origin, sexual orientation, gender identity, age, marital or family status, disability, Veteran status, and any other status. Achieving diversity across these categories will serve to make our company stronger and our product better.
