Job description

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. Our structure is flat, and collaboration matters more than hierarchy. 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

The CISO is our chief protector. Our infrastructure, threat model, and customer expectations are more complex than a typical mobile carrier or a typical software company. Your challenge is to enable rapid product innovation without compromising on our goal to be the most secure commercial mobile network on the planet. You'll own the strategy and execution of security across our network, products, and corporate systems and work as a partner to Engineering and the executive team.

This is a build-and-defend role, not a maintain-the-status-quo role. You will immediately take ownership of a highly technical, responsive, and ambitious security, IT, and compliance org. Your mandate is to resource, mature, and scale this team to stay ahead of threats and enable Cape’s rapid growth.This role is based out of our NYC or DC office and reports to our founder and CEO John Doyle.

What You’ll Work On

• Own Cape's end-to-end security strategy — network infrastructure, product/application security, cloud and corporate IT, and physical/personnel security.

• Build and lead a security team capable of defending a carrier-grade network against sophisticated, well-resourced adversaries, including nation-state actors.

• Design and drive the security architecture and controls for a cellular network we operate ourselves, from the radio access network through core infrastructure and subscriber data systems.

• Partner closely with Engineering leadership to embed security into the product development lifecycle.

• Lead teams conducting threat modeling, penetration testing, red-teaming, and incident response programs.

• Set and communicate security policy to the board and executive team, translating technical risk into business terms and making tradeoffs with speed of execution.

• Vet and manage relationships with external security vendors, auditors, and researchers, including running a responsible disclosure / bug bounty program.

• Champion a security-first culture across the entire company, not just within the security team.

Experience

• 10+ years in information security, with at least 5 years in a senior security leadership role (CISO, VP Security, Head of Security) at a company with meaningful infrastructure or regulatory complexity.

• Eligible and willing to obtain TS/SCI clearance.

• Experience managing geographically dispersed teams of engineers.

• A track record of building security teams and programs from an early stage, not just operating a mature one you inherited.

• Deep technical credibility — you can go toe-to-toe with your best engineers on architecture and risk, while also speaking fluently to executive leadership and the board.

• A genuine belief that privacy and security are inseparable, and that protecting users sometimes means resisting internal and external pressure to compromise on either.

• Excellent judgment under ambiguity and the ability to move fast without cutting corners that matter.

• (Bonus Points) Direct experience securing telecom, network infrastructure, or other critical infrastructure — you understand things like SS7, radio networks, or core carrier systems, or you've secured environments of comparable complexity (e.g., cloud infrastructure providers, fintech, critical infrastructure).

• (Bonus Points) Experience securing an environment with Forward Deployed Engineers and the complexity around high risk travel.

Compensation

We offer competitive compensation that is geo-adjusted based on your location, along with meaningful equity so you share in the value you help create. Salary range for this role in NYC/DC is $300,000 - $350,000 depending on experience and interview performance and location.

• We believe companies exist to build awesome things and take care of the people who build them, so we offer top-tier healthcare, 401(k) matching, and a generous vacation policy that our team actually uses to recharge.
