About Us

Codan Limited is an Australian company listed on the Australian Securities Exchange (ASX). Codan is a global group of innovative, technology companies, focused on transforming lives through critical technologies. We deliver solutions across communication, detection and connection.

We have a global footprint with offices in Australia, Brazil, Canada, Denmark, UAE, Ireland, Mexico, Singapore, the UK, and the USA. We sell our products in over 150 countries to customers such as global governments, businesses, NGOs, aid and humanitarian organizations, security and military groups, public safety, emergency response, broadcast, and consumer markets.

We deliver innovation, wherever you are.

What will you be doing?

Reporting to the IT Lead – North America, the Network Administrator will play a key role in maintaining, securing, and enhancing Codan Group’s network and systems infrastructure. Based in Ashburn, this role is responsible for the day-to-day operational delivery of network services while also contributing to projects that drive secure, reliable, and efficient technology improvements across the organization.

This is a hands-on, technically focused role that works closely with the wider Group Systems team, internal stakeholders across global business units, and external vendors.

Key Responsibilities Include:

Managing and maintaining enterprise firewall environments, including policy design, rule management, firmware updates, and security hardening.
Ensuring reliability and performance across core network infrastructure, including switches, routers, wireless networks, and VPN technologies.
Applying and validating network security controls, including firmware updates, vulnerability remediation, access management, and compliance with security standards.
Executing planned network changes, upgrades, and configuration updates accurately and on schedule.
Configuring, installing, and maintaining networking hardware, software, and communications equipment across local and remote (overseas) sites.
Providing remote and onsite systems, server, and desktop support, including patching and upgrades to address vulnerabilities and performance issues.
Collaborating with internal stakeholders and external service providers while supporting user-facing helpdesk tickets related to network and systems.

About You:

The ideal candidate is a motivated and technically capable Network Administrator with strong hands-on networking experience and a proactive approach to service delivery. A strong commitment to customer service, security, and operational excellence is essential, along with the ability to work autonomously while collaborating effectively within a global team environment.

To be successful in this role, you’ll ideally have:

Advanced hands-on experience administering enterprise firewall platforms, including policy creation, rule review, security hardening, firmware upgrades, and threat mitigation.
Extensive knowledge of firewall appliances and a solid understanding of networking principles (LAN/WAN).
Hands-on experience with networking, wireless, security appliances, and virtualization tools.
Working knowledge of Microsoft operating systems and applications.
Strong problem-solving skills with the ability to prioritize competing demands.
Excellent communication, interpersonal, and customer service skills with a collaborative mindset.

This role requires eligibility to obtain and maintain a U.S. security clearance, as well as the ability to travel domestically up to 10%, including occasional travel to Washington State for team engagement and project support.

Benefits and Culture

Our culture is supportive and collaborative. You will be part of a multidisciplinary team where we share our ideas and innovation is strongly encouraged. We are looking for someone with genuine passion and a can-do attitude for what they do.

Our staff receive 15 days accrued paid time off per year, 10 Federal holidays plus an additional 2 floating holidays, an opportunity to join our sponsored health and welfare plan, a generous 401k plan with matching employer contribution, an Employee Assistance Program, and more.

Additionally, we offer flexible core working hours and we take a personal approach to training and development. Enjoy working as part of a global organization with teams in the USA, UK, UAE, Ireland, Mexico, Brazil, Denmark, Singapore, and Australia.
