Cyber Security Specialist

About our client

Our client operates within a critical infrastructure environment where security, stability and uptime are non-negotiable. They manage complex, live systems across cloud, network and on-prem platforms, with a strong focus on practical, real-world security outcomes rather than theory.

This is a business that values hands-on expertise — where engineers are trusted to solve problems properly and contribute to meaningful improvements across their environment.

About the role

This is a highly hands-on role for a security-focused engineer who is comfortable operating in live, fast-paced environments.

You’ll act as a key SME across security operations, working across Windows, Linux, networking and cloud platforms. The role blends detection/response with practical engineering — from platform hardening and identity controls through to troubleshooting complex incidents.

Key areas of focus include:

• Acting as the go-to SME across security and operations for Windows, Linux and cloud environments
• Supporting platform hardening, patching and security standards across systems
• Handling BAU operations and stepping into incidents when things go wrong
• Troubleshooting network issues end-to-end — from connectivity through to security and identity-related problems
• Administering and securing Linux environments (access control, patching, troubleshooting)
• Supporting Microsoft GSA configurations and policy enforcement
• Managing Azure tenants with a focus on security posture and operational stability
• Working closely with infrastructure, network and security teams to resolve root causes — not just surface issues
• Contributing to documentation and continuous improvement of operational practices

This is a role for someone who enjoys being in the detail and solving real problems in production environments.

The successful candidate

You’re a hands-on operator who thrives in environments where things don’t always go to plan — and you’re comfortable working through that.

You’ll bring:

• Strong experience in high-paced, real-world operational environments
• Solid Linux administration skills, with a security focus
• Background in security operations / support (as opposed to purely project-based work)
• Strong networking fundamentals and the ability to troubleshoot across layers
• Hands-on experience with Microsoft GSA
• Experience managing and supporting Azure environments
• Strong knowledge of Microsoft Entra ID, particularly Conditional Access and identity controls

In addition, you’ll be:

• Comfortable handling incidents, escalations and complex troubleshooting
• Solutions-focused, with a bias toward fixing root causes
• Able to collaborate effectively across infrastructure, network and security teams
• Practical in your approach — able to balance security, usability and operational needs

Nice to have:

• Exposure to Cisco security tools (WSA / ESA, WAF)
• Experience in critical infrastructure environments
• Familiarity with Zero Trust principles

What’s on offer?

• Initial 6+ month contract with strong extension potential
• Competitive day rate ($450–$500 depending on experience)
• Opportunity to work in a critical infrastructure environment where the work genuinely matters
• Broad exposure across security, cloud, network and infrastructure domains
• A capable, no-nonsense team that values practical expertise
• Strong work-life balance — not a burn-out culture
• A role where your input is trusted and has a real impact
