Wireless Network Architect

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 is seeking a Wireless Network Architect who combines deep expertise in planning, building, and operating cellular networks with the vision and courage to disrupt legacy approaches and reimagine the future of telecom. You're not just an expert in telecom architecture—you're driven to make an impact. You want to join a fast-growing company where your work directly supports the U.S. and its allies in strengthening national security. This is an opportunity to contribute to projects that truly matter—shaping the geopolitical landscape in an era where telecom is an essential element of modern warfighting. In this role, you'll bring the technical depth to go toe-to-toe with vendors, partners, and internal teams as we implement a next-generation, cloud-based Core network. You understand IMS, packet cores, and the edge elements that integrate with other networks—including 4G and 5G variants such as HSS, UDM, and UDR. You are both an architect and a builder: capable of seeing the big picture and inventing what's next, while unafraid to roll up your sleeves and execute. This is a hands-on role where strategy and delivery go hand in hand.

Here are some ways you'll make an impact

• 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 3GPP/GSMA functions, or inventing new protections against malicious actors.
• Stand up new network instances in new regions or with functionality tailored to evolving customer needs.
