Detection Engineer

* Sheffield or London – 1–2 days per week onsite

* Initial 6-month contract

* £600 per day via umbrella

* Inside IR35

We’re working with a leading bank to appoint Detection Engineers to join a growing internal defensive security team.

The team is expanding its dedicated detection capability, moving from detection engineering being a secondary responsibility within the Cloud function to a specialist, full-time discipline. You’ll work as part of a global team across the UK, Poland and Mexico.

The role is focused entirely on defensive security and threat hunting, with an emphasis on building high-quality detections rather than simply increasing volume.

Key responsibilities:

* Develop high-quality detection use cases from external threat intelligence and internal security data

* Analyse intelligence and translate it into effective detections for the organisation

* Use Red Team outputs to identify gaps, understand attack techniques and determine where to detect malicious activity

* Conduct threat hunting and identify opportunities to improve defensive coverage

* Work closely with security and technology teams to understand the environment and optimise detection capability

* Deliver detection engineering through Agile, sprint-based and Scrum ways of working

Requirements:

* 3–5 years’ experience across technology operations, development or security

* Hands-on experience writing and developing security detections

* Strong understanding of threat hunting and defensive security

* Experience working with threat intelligence and translating intelligence into actionable detections

* Experience within a large financial services organisation or similarly complex, highly regulated environment

* Comfortable working in an Agile/Scrum delivery environment

* Curious, technically minded and hungry to investigate how attackers operate and how they can be detected
