About this 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. 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 We are seeking an experienced Security Engineer with expertise in corporate security to join our team. As a strategic partner, you will make an immediate impact by leveraging your expertise across identity, endpoint, network, and information security alongside IT, engineering, and business teams. This role is pivotal in reducing risk across our corporate environment, covering employee-facing systems, internal infrastructure, and third-party risk, and will be responsible for designing, implementing, and maintaining security measures that comply with regulatory standards, enhance internal processes, and minimize data security risks. Through developing ongoing security strategies, technologies, and a strong security culture, you will support the organization's business objectives and daily operations. Responsibilities - Design, implement, and manage security controls and policies across corporate IT systems, focusing on the confidentiality, integrity, and availability of employee, customer, and business data. - Own and mature identity and access management (IAM/SSO/MFA), endpoint security (EDR, MDM), and email/network security (phishing defense, DLP, firewalls, VPN) across the organization. - Perform comprehensive security assessments of corporate systems and vendors to identify vulnerabilities, assess risk, and recommend actionable mitigation strategies. - Establish governance, guardrails, and monitoring for emerging employee tooling, including the associated data-handling, access, and third-party risks. - Own the vulnerability management lifecycle across the corporate fleet: scanning, risk-based prioritization, remediation and patch SLAs, and closure tracking across endpoints and internal systems. - Lead security awareness and phishing simulation programs to build an organization-wide culture of security. - Contribute to compliance and audit efforts as needed, lending security context where it helps the business move faster. - Assess and manage third-party/vendor security risk, including security questionnaires, contract reviews, and ongoing vendor monitoring. - Assist in running and addressing findings from penetration tests, red team exercises, and internal audits, ensuring prompt and effective remediation. - Stay informed about the latest security threats, vulnerabilities, and compliance mandates affecting corporate environments; provide strategic guidance on technologies and best practices. - Investigate security incidents and insider-threat concerns in partnership with HR, Legal, and IT as needed. - Raise the security bar across the company by mentoring engineers and partners on secure practices, fostering a culture of security awareness and continuous improvement. - Collaborate with stakeholders to integrate security requirements effectively into IT projects and broader business initiatives. Preferred Experience - Bachelor's degree in Computer Science, Information Security, or a related field (or equivalent experience). Advanced degrees or certifications (e.g., CISSP, GIAC, Security+, CISM) are advantageous. - A minimum of 5 years of experience in information security, with meaningful experience across corporate/IT security domains (identity, endpoint, network, GRC). - Deep understanding of enterprise identity providers and SSO/MFA platforms, endpoint/EDR tooling, MDM platforms, and email security tooling. - Working knowledge of common compliance frameworks (e.g., SOC 2, ISO 27001). - Familiarity with government/public-sector security frameworks (FedRAMP, FISMA, NIST SP 800 series, CJIS) is a plus, given Cape's government-facing customer base. - Working knowledge of consumer privacy regulations (GDPR, CCPA, and other regional privacy laws) as they apply to handling customer data. - Exposure to secure software development lifecycle (SSDLC) practices and partnering with engineering on secure design reviews. - Proficiency in scripting or automation (Python, shell scripting, or similar) to streamline security operations and reporting. - Familiarity with vendor/third-party risk management processes and tooling. - Solid knowledge of network security, encryption tech
