Senior System Engineer - #1697842

Senior Systems Administrator – Hybrid but mainly onsite - 4 days p/week onsite 



Location: Cardiff, South Wales



A client of ours needs a hands-on Systems Administrator to stabilise, secure, and support their IT environment. It’s a standalone, high-trust role — you’ll be the go-to expert for infrastructure, cloud, and security



This isn’t BAU support. It’s for someone who’s been around the block and can lead the back-end estate while upskilling junior IT staff



What You’ll Be Doing



Running the show across Microsoft 365, Azure AD, and on-prem Windows Servers



Getting hands-on with Cisco Meraki, Mimecast, backups (Veeam/Acronis), and general networking



Being the final escalation point for tricky issues — no ticket-chasing



Helping deliver small infrastructure projects and supporting ERP systems (IFS/SAP/Oracle etc.)



Improving documentation, security posture, and general system resilience



Working closely with the senior management and mentoring junior team members



What You’ll Need



5–7 years in a systems/infrastructure role — ideally as a senior, lead, or sole admin



Strong experience with:



Microsoft 365 (Exchange, SharePoint, Teams)



Azure AD / Entra ID, Group Policy



Cisco, ideally Meraki, general networking



Mimecast, backups (Veeam/Acronis/Barracuda)



ERP support (any major system — e.g. IFS, SAP, Dynamics)



Security-aware mindset (ISO 27001, ITIL frameworks, MFA, patching, etc.)



Why Take This Role



Real ownership — not stuck in red tape or tiered service desks



Get things done — decisions are quick, and your input matters



Straight-talking environment — no corporate waffle, just solid IT



On-site in South Wales— ideal for someone local or willing to travel
