3rd Line Support Engineer

We're looking for an Infrastructure Operations professional to join our clients Infrastructure projects team in Hertfordshire. This role sits at the heart of their infrastructure operations, where you'll identify automation opportunities and build intelligent solutions that make our systems more efficient, resilient, and easier to support.

You'll play a key role in shaping how IT is delivered across the organisation. From Scripting and deployment through to monitoring, patching, and incident response, your work will directly influence the stability, security, and scalability of our infrastructure.

The Role

You'll be responsible for monitoring and maintaining our infrastructure, ensuring services remain reliable, secure, and compliant. Acting as an escalation point, you'll take ownership of complex 2nd and 3rd line issues that require advanced technical expertise, delivering long-term solutions rather than quick fixes.

A major focus of the role is automation. You'll proactively identify inefficiencies and design automated workflows that reduce manual effort, improve response times, and enhance operational consistency. You'll also collaborate closely with Infrastructure Operations, Service Desk, and Field Services teams to embed automation into everyday processes and promote best practices across the business.

• PowerShell (primary Scripting and automation language)
• Python and Bash (Nice to have)
• Microsoft Azure
• Office 365/Microsoft 365
• Ansible and Terraform
• Microsoft Intune

You'll also document automation solutions clearly and share knowledge with colleagues, helping drive adoption and continuous improvement across the wider IT function.

You're a technically strong infrastructure professional with demonstrable 2nd and 3rd line experience, but what really sets you apart is your problem-solving mindset and passion for automation. You're comfortable working under pressure, take ownership of issues, and enjoy improving how systems and teams operate.

Your background and strengths include experience with:

• 3rd line infrastructure support with an automation focus
• Cloud and Microsoft enterprise environments
• Scripting, workflow automation, and configuration management
• Structured service delivery and ITIL-aligned processes

You'll bring strong communication skills, a customer-focused approach, and the ability to engage effectively with both technical and non-technical stakeholders. You're detail-oriented, process-driven, and committed to maintaining a stable and secure infrastructure.

If your experience doesn't align perfectly with every requirement, we still encourage you to apply. We value potential, curiosity, and a willingness to learn - and you may be exactly the right fit for their team.
