Job Title: Senior Product Cybersecurity Engineer – Platform Security Job Location: Montreal, QC Job Code: 44138 Job Schedule: Day Shift Compensation Range: Between $102,0 00 - $ 152,000 CDN annually L3Harris MAPPS' Integrated Platform Management System (IPMS) is a mission-critical solution deployed on various military and cruise ships. It integrates and controls nearly all onboard equipment, combining L3Harris-developed technologies with commercial off-the-shelf (COTS) components. The IPMS operates within its own dedicated on-premises IT environment, using standard infrastructure elements such as virtualized servers, networking equipment, storage systems, databases, domain controllers, Active Directory, automation, and many others. As a member of the Cybersecurity team, you will play a pivotal role in strengthening the system’s security posture across all phases of the development lifecycle—from initial design to final deployment. You will work closely with software development teams, DevOps, and Integration & Test (I&T) engineers in a highly collaborative environment. Because IPMS is a complete and self-contained solution, we value broad cybersecurity expertise spanning software, hardware, and IT infrastructure. If interested, you may also have the unique opportunity to support deployments directly onboard ships. Essential Functions: Assess, implement, and manage a range of cybersecurity and IT technologies integrated into the IPMS solution, as described above. Support cross-functional teams by clearly communicating cybersecurity concepts, providing guidance, and helping to prioritize security-related tasks. Proactively identify, assess, and remediate security vulnerabilities within the system, based on risk and impact. Develop tools, scripts, and automation to enhance cybersecurity operations; may also involve contributing to security-relevant code. Define and document cybersecurity requirements for other software components to ensure compliance with established security standards. Deploy, configure, and maintain cybersecurity solutions to continuously improve the security posture of the overall system. Qualifications: Minimum of 10 years of experience in cybersecurity serving as a Senior IT/Security Administrator, Security Engineer, or Security Architect within engineering-driven product development environments, including hardware and software product development for on-premises platforms, embedded systems, or connected devices. Deep expertise in the following areas: Linux System Administration: Extensive hands-on experience with Linux-based infrastructure and administration, including centralized identity and access management (e.g., LDAP, FreeIPA, Kerberos), privilege and role-based access control, system hardening, patch and package management, SSH and certificate-based authentication, and PKI/certificate lifecycle management.
