- Domain
- Cybersecurity
- Entry
- £32–40k
- Senior
- £52–65k
- You enjoy adversary behaviour more than alerts and dashboards
- You can write code, properly, not just KQL one-liners
- You want a seat that compounds, every detection you write is yours
- You're patient enough to tune for months before you see clean signal
- You're hoping detection engineering will get you off shift work without doing the homework
- You don't enjoy reading other people's incident reports for fun
- You can't work without immediate feedback, the loop here is long
What "doing well" looks like in the seat
- Your detections have regression checks and an owner for tuning
- You can translate a relevant threat hypothesis into a tested detection
- Red team finds your rules before they find your gaps
- Other analysts copy your detection structure without being told
A rule that fires is not necessarily useful. The role needs access to telemetry, realistic validation and a feedback loop with the analysts who investigate its alerts.
