As an Internet Systems Administrator with the Department of National Defence, you will design, implement, and maintain the network infrastructure and internet systems that support Canada's defence operations. You will work with cutting-edge technology to ensure reliable, secure, and efficient connectivity across DND facilities and operations. This role is critical to enabling military personnel, civilian staff, and defence partners to communicate and access the information systems they need to carry out their missions.
Your day-to-day responsibilities will include monitoring network performance, troubleshooting connectivity issues, managing firewalls and security protocols, and implementing system upgrades. You will collaborate with other IT specialists, security teams, and infrastructure operations staff to maintain compliance with Government of Canada and DND security standards. You will also provide technical support to end users and document system configurations and changes.
Internet Systems Administrators in DND work in both office-based environments and technical operations centres. You may be based at a military installation, National Defence Headquarters in Ottawa, or a regional operations centre. The role involves on-call support and may occasionally require after-hours work to handle critical system issues or perform maintenance during scheduled windows.

Training
To qualify for an Internet Systems Administrator position, you typically need a diploma or degree in computer science, information technology, computer networking, or a related field from a recognized post-secondary institution. Some positions may accept relevant work experience in lieu of formal education.
Professional certifications are highly valued and may be required or preferred, including CompTIA Network+, Cisco Certified Network Associate (CCNA), Microsoft Certified: Azure Administrator, or similar industry-recognized credentials. DND encourages ongoing professional development and may support employees in obtaining additional certifications such as Certified Information Systems Security Professional (CISSP) or specialized certifications in emerging technologies.
Once hired, you will complete Government of Canada security screening and may require a Secret or Top Secret security clearance depending on the specific position. DND provides training on its specific systems, networks, and security protocols. You will have access to professional development opportunities, including online courses, workshops, and conferences to keep your skills current with evolving technology and security threats.
Entry Plans
Entry to the Internet Systems Administrator career in the Public Service typically occurs through a competitive recruitment process managed by the Treasury Board of Canada Secretariat (TBS) and the Public Service Commission (PSC). DND posts positions on the Government of Canada Job Bank and on its own recruitment portal.
If you are a recent graduate, look for student recruitment programs such as the Federal Student Work Experience Program (FSWEP) or the Post-Secondary Recruitment Campaign (PSRC), which can lead to permanent employment after graduation. These programs allow you to gain hands-on experience and familiarity with DND systems.
If you are already working in the federal Public Service, you may be able to apply for positions through internal competitions or be selected from an established staffing pool. Lateral moves from other IT roles within government—such as Help Desk Support, Database Administrator, or IT Security Analyst positions—are common entry points. Some positions may be filled through non-advertised processes if you are already a public servant with the required qualifications.
For those with relevant private-sector experience, external competitions are regularly advertised. Ensure your resume clearly demonstrates your technical skills, certifications, and experience with network administration, system maintenance, and IT project involvement.
Part-Time Options
Part-time and flexible work arrangements for Internet Systems Administrators at DND are possible but limited due to the nature of the role. Network and internet systems require ongoing monitoring and maintenance, which may necessitate regular full-time presence. However, some positions—particularly those focused on planning, documentation, or specialized projects rather than live operations support—may offer flexibility.
Remote work options have expanded across the federal government and DND in recent years. Depending on your specific duties and security requirements, you may be able to work remotely for certain tasks such as documentation, training, or administrative work. However, hands-on network maintenance and emergency troubleshooting typically require on-site presence in operations centres or technical facilities.
If you require part-time work or flexible arrangements, discuss options with your manager and the DND Human Resources team when you apply or when you begin the position. Arrangements will depend on operational needs, security clearance requirements, and the specific duties of your role. Job sharing and compressed work weeks may be available in some circumstances.
