DSM Group is a growing IT Support and Infrastructure provider delivering managed IT services, hosted platforms, backup solutions and secure colocation from our purpose-built eco data centre in Peterborough.
We are seeking a technically strong IT Operations Manager who remains hands-on while leading the technical direction and daily operations of our managed services team.
This is not a purely managerial role. You will still build, troubleshoot, design and improve environments — while ensuring service standards remain high and engineers are aligned.
The Role
You will take ownership of technical operations across:
- Managed IT support clients
- Microsoft 365 and Azure environments
- Server and virtualised infrastructure
- Backup and disaster recovery platforms
- Firewalls and networking
- 3CX telephony systems
You will work closely with the Data Centre Manager to ensure performance, resilience and scalability across hosted and colocation platforms.
This role suits a senior technical engineer ready to step into leadership — or an existing operations lead who still enjoys being technically involved.
Key ResponsibilitiesTechnical (Primary Focus)
- Design, implement and maintain Microsoft 365 and Azure environments
- Administer Windows Server, Active Directory and Group Policy
- Oversee virtualisation platforms and server infrastructure
- Configure and manage firewalls and core networking
- Maintain backup and disaster recovery systems
- Support and manage 3CX VoIP deployments
- Lead technical escalations and complex issue resolution
- Ensure patching, security hardening and system integrity
- Conduct disaster recovery testing and infrastructure reviews
You will be expected to actively participate in technical delivery — not just delegate.
Operational & Team Leadership
- Provide guidance and technical oversight to engineers
- Manage escalations and quality control
- Improve documentation and operational standards
- Monitor ticket flow and SLA performance
- Support recruitment and mentoring of technical staff
- Collaborate with the Data Centre Manager on infrastructure planning
Technical Skill Requirements
Strong working knowledge of:
- Microsoft 365 (Exchange, SharePoint, Teams, Entra ID)
- Microsoft Azure
- Windows Server & Active Directory
- Hyper-V / VMware
- Firewalls (configuration and security policy management)
- Networking fundamentals (VLANs, routing, switching, VPNs)
- 3CX or similar VoIP platforms
- Backup & Disaster Recovery solutions
You should be confident logging into a firewall, diagnosing a routing issue, reviewing Azure policies or troubleshooting AD replication — without relying entirely on others.
Experience Required
- 5+ years in an MSP or multi-client IT environment
- Experience handling technical escalations
- Previous team lead or supervisory experience preferred
- Experience working in structured environments with documentation and standards
