About the role

Diacom is seeking a Senior MSP Engineer to lead the delivery, support, and continuous improvement of managed IT, network, and security services across a diverse customer base.

This is a senior technical role for an experienced engineer who enjoys solving complex infrastructure challenges, leading customer-facing projects, and helping shape high-performing managed services environments. You will act as a senior escalation point, drive service quality and operational excellence, and play a key role in the strategic growth of our managed services portfolio.

You will also mentor junior engineers, contribute to service development, and act as a trusted technical advisor to customers.

What you’ll do

Managed services delivery and support

Design, implement, and support managed IT, network, and security solutions across customer environments
Act as the Level 3 escalation point for complex technical issues across infrastructure, networking, and security platforms
Maintain high availability, performance, and security across managed environments
Deliver proactive maintenance, optimisation, and continuous improvement across supported systems

IT, network, and security engineering
You will deploy, configure, and support solutions including:

Microsoft 365, Windows Server, and Windows Client
Next-generation firewalls including SonicWall, Palo Alto, and Fortinet
Network switching, wireless, segmentation, VPNs, and high-availability architectures

You will also:

Manage firewall policies, threat prevention tuning, and security hardening
Design and implement secure network architectures aligned to operational and customer requirements

Security and compliance

Implement and manage firewall rulebases, IPS/IDS, threat protection, and secure remote access
Apply network segmentation and Zero Trust security principles
Perform security assessments and support remediation of vulnerabilities
Ensure customer environments align with current security best practices and compliance requirements
Apply best practices across Microsoft Intune, Microsoft 365, Windows, and Windows Server

Troubleshooting and escalation

Diagnose and resolve complex issues across customer infrastructure
Perform root cause analysis and implement preventative improvements
Provide expert escalation support and technical guidance to Level 1 and Level 2 engineers

Projects and service improvement

Lead the technical delivery of upgrades, migrations, and new deployments
Work with internal teams to deliver integrated customer solutions
Contribute to the development and enhancement of managed service offerings

Documentation and reporting

Maintain accurate technical documentation across customer environments
Produce reports on performance, incidents, and service delivery metrics
Ensure all work is logged and tracked in line with internal processes

Leadership and collaboration

Mentor junior engineers and support knowledge sharing across the team
Work closely with account managers and customers to align technical solutions with business outcomes
Build trusted relationships with customers as a senior technical advisor

What we’re looking for

Required

Bachelor’s degree in Information Technology, Computer Science, or a related discipline — or equivalent practical experience
7–9 years’ experience in a managed services, infrastructure, or network engineering environment
Strong expertise across networking and security technologies
Proven experience supporting complex customer environments
Advanced troubleshooting, analytical, and problem-solving capability
Strong communication skills with experience working directly with customers

Preferred

Vendor certifications such as Palo Alto PCNSE, Fortinet NSE, or Microsoft certifications
Strong understanding of modern IT infrastructure and managed services delivery
Experience with RMM platforms and Microsoft Intune
Scripting or automation experience using Python or PowerShell
Experience leading technical projects and mentoring engineers
Ability to produce clear, high-quality technical documentation and operational standards

Working environment

Hybrid role with time split between office and customer sites
Regular customer site visits will be required
Participation in an on-call rotation and occasional after-hours support

Why join us?

At Diacom, you’ll work with a broad range of customers, modern infrastructure technologies, and a collaborative technical team that values quality engineering, customer outcomes, and continuous improvement. This is an opportunity to take ownership of complex environments while helping shape the future of our managed services offering.
