Security Engineer

Senior Security Engineer / Consultant (Security Data & Detection) Contract – Hybrid – Bristol - £500 a day Outside IR35

This is a customer-facing Security Engineer role focused on helping organisations turn high-volume security data into meaningful, cost-effective outcomes.

We’re not looking for someone who just wants to sit inside a SIEM and engineer in isolation.

Most customer conversations start with "our SIEM is too expensive". Your role is to go deeper:

• What security data is the business generating?
• What EDR/XDR platforms are in place?
• What outcomes are they trying to achieve with that data?
• Where is noise driving cost?
• Where are the detection gaps?

You’ll lead discovery sessions, engage at a business outcome level
, and translate security objectives into practical data pipeline designs. Working closely with engineers, you’ll help deploy solutions that improve detection coverage while reducing ingest spend.

This role sits at the intersection of security engineering, data architecture and consulting
.

• Run customer discovery workshops focused on security data and detection objectives
• Design end-to-end security data pipelines feeding SIEM and analytics platforms
• Optimise ingest by reducing low-value event data and improving signal-to-noise
• Map data sources to use cases and detection logic
• Advise on EDR/XDR, log sources and security data flows
• Help build reusable delivery patterns, runbooks and onboarding models

• Security engineering, SIEM or detection engineering
• Data pipeline engineering with strong security exposure
• Consultancy, MSSP, SRE or platform roles that became customer-facing

You’re comfortable speaking to both engineers and security leaders, and you focus on outcomes rather than tooling alone.
