About the role
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 engineering team is small by design and ambitious by nature. We build cryptographic primitives, 5G core network functions, zero-trust edge systems, and threat detection pipelines - problems that don't have StackOverflow answers. The people doing that work deserve an environment that gets out of their way. As a Developer Experience Engineer, your job is to make Cape's engineers measurably faster, less frustrated, and more confident in what they ship. That means owning the internal platforms, tooling, and workflows that engineering depends on — from CI/CD pipelines and local development environments to AI-assisted development workflows, test infrastructure, and release processes. This is not a support role. It is a product role where the customer is the engineering organization, the product is the development loop, and quality is measured in time-to-merge, build reliability, AI-augmented velocity, and the number of times an engineer has to context-switch to deal with infrastructure instead of product. You will work across the full engineering organization — embedded closely with platform, product, and security teams — and report to engineering leadership. Your impact will be felt by every engineer at Cape.
