Wireless Network Architect

Wireless Network Architect

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.

• Design and deliver core networks that support essential features (voice, data, messaging), address customer use cases, and solve hard problems with novel, never-been-done solutions—while ensuring scale and reliability.
• Partner across teams and vendors to stitch together solutions and bring them successfully to market.
• Implement new features with zero disruption to live users through well-planned MOPs, maintenance windows, test plans, and phased rollouts.
• Troubleshoot deeply—dig into network traces with partners and vendors to isolate root causes and resolve complex issues.
• Interconnect networks—from private to commercial, roaming to MVNO—ensuring seamless interoperability.
• Drive new standards in security and privacy, whether by encrypting data, eliminating unnecessary storage (e.g. CDRs), augmenting 3
  
  GPP/GSMA functions, or inventing new protections against malicious actors.
