Security Engineer — Microsoft Sentinel & Defender
Cardiff / Remote (3/4 days per month onsite)
Permanent
£50,000
I'm working with a Microsoft security partner to recruit a Security Engineer into its Security Operations team. This is a great opportunity for an Analyst to step into and Engineering position, or a Junior Engineer looking for a more supportive and collaborative environment.
You’ll help develop and improve security capabilities across Microsoft Sentinel and Defender XDR, working directly with clients to strengthen their environments. This is a hands-on engineering position, with incident response involvement focused on escalations rather than routine alert monitoring.

Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
