Software Engineer, Infrastructure

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.

To join our team, you should be excited to:
Dive into a well-funded but early-stage startup. We’re in a scrappy phase, be comfortable getting a little uncomfortable.
Reclaim some of the personal privacy we have all sacrificed as smartphone adoption has grown.
Flex your technical skills on hard, important problems with serious implications for consumer privacy and national security.
Push the envelope - we are using new technology in novel ways.
Work on greenfield problems. Starting new projects from the ground up. Shaping the stack, practices, and getting the opportunity to try new tools and technologies.
Work in person! There are no facetime requirements or set hours here, and we all take work from home days. But our default work location is our DC or NY office, and we enjoy the informal culture and serendipity that in-person work enables.
We’re offering competitive salary, benefits, and equity with early-stage upside.
Be responsible for the full lifecycle development of our privacy-focused telecommunications and deployment infrastructure.
Build, integrate, and maintain our instrumentation and monitoring infrastructure and tooling for improving the reliability, availability, and performance of our system.
Help solve issues proactively before they become issues.
Build new or integrate with existing telecommunications infrastructure and components.
Own the technical accreditation and compliance process end-to-end for FedRamp.
Shape and influence what great software engineering practices look like.
Balance short term critical business needs with long term product vision and roadmap.
