Network Security Engineer - Global Security Operations Centre (GSOC)

Be the link between threat and defence.

At The Missing Link, we don’t just respond to cyber threats, we stay one step ahead. As one of Australia’s most awarded IT providers, now proudly backed by global technology leader Infosys, we have spent more than 28 years helping organisations thrive through world‑class Cyber Security, IT & Cloud, and Automation solutions.

With over 200 passionate team members and a culture built on inclusion, innovation and impact, we offer more than a job, we offer a place where your expertise is valued, your growth is supported, and your contribution truly matters.

The Opportunity

We are looking for a Network Security Engineer to join our Global Security Operations Centre (GSOC), a 24x7 managed service providing round‑the‑clock protection to clients across a diverse range of industries.

This is a hands-on engineering role (not an analyst position), ideal for someone who enjoys working directly with market‑leading security technologies and solving complex security challenges in real time.

A Day in the Life

As part of our GSOC Engineering team, you will:

• Provide Level 1 and Level 2 support across a broad security stack including Palo Alto, CyberArk, Fortinet, Cisco, Checkpoint, Cloudflare, Zscaler and SASE solutions

• Configure, maintain and troubleshoot security platforms across on‑prem and cloud environments
• Work closely with Security Architects, Engineers, MDR (Watcher) teams and clients to transition solutions from project delivery into managed services
• Assist Senior SOC Engineers with incident response and threat containment
• Continuously improve SOC processes, procedures, and best practices
• Support clients during business hours, with exposure to live incidents and real‑world attack scenarios

You will work a four‑days‑on, four‑days‑off rotating shift pattern, with the flexibility of remote work, while gaining exposure to major Australian enterprises and cutting‑edge security technologies.

Essential Experience & Skills

• Minimum 5+ years’ experience in Network Security within a Managed Service Provider or similar environment

• Hands‑on experience with NextGen Firewalls, Cloud SASE (e.g. Zscaler), WAFs, PAM solutions, and related security technologies
• Strong understanding of networking fundamentals (OSI Model, TCP/IP, network architectures)
• Experience with network segmentation, URL filtering, packet inspection, certificates, virtualisation and cloud security
• Proven troubleshooting, debugging, and problem‑solving skills in fast‑paced environments
• Ability to manage multiple tasks while meeting tight deadlines
• Experience briefing clients and providing security recommendations
• Strong collaboration and interpersonal skills, contributing to a positive, high‑performance team culture

Desirable

• Broader understanding across applications, operating systems, databases, storage and backups

• Vendor certifications or active pursuit of certifications (CyberArk, Cloudflare, Palo Alto, Cisco, Checkpoint, SASE)
• Exposure to Infrastructure as Code (IaC) in AWS or Azure
• Scripting or automation experience (PowerShell, Python, Bash)
• Passion for continuous learning — labs, home networks, forums, webinars and industry communities
• Interest in professional certifications such as ISC2, ISACA and vendor programs

A great company culture is very important to The Missing Link. We genuinely care about our people and our culture. Some of our favourite perks include:

• A supportive, collaborative and respectful environment

• Company‑paid training and certifications
• Clear pathways for career development and progression
• Exposure to leading technologies and complex enterprise environments
