Location: UK (fully remote - work from anywhere worldwide)
Salary: Up to £100,000 + benefits

About the role

We're looking for a hands-on Cyber Threat Detection Engineer to build high-fidelity detections based on real-world attacker behaviour. You'll work with global telemetry, honeypots, and deception systems to identify exploitation, develop detection pipelines, and convert threat intelligence into actionable insights.


Key responsibilities

  • Own design and operation of detection logic for live attacker activity, including zero-day and N-day exploitation

  • Build and maintain pipelines that ingest, enrich, and correlate telemetry and threat intelligence

  • Reduce noise, validate detections, and tune signals at scale

  • Rapidly respond to emerging threats and translate exploitation into customer insights

  • Produce detection research, threat reports, and mentor peers on detection standards


About you

  • 5+ years in detection engineering, threat research, SOC, IR, or offensive security

  • 3+ years building production-ready detections from attacker behaviour

  • Strong knowledge of threat intelligence, MITRE ATT&CK, exploit lifecycles, and tradecraft

  • Hands-on experience with honeypots, deception, or large-scale telemetry

  • Skilled in Python and familiar with OpenSearch / ELK stacks

  • Comfortable in high-noise, fast-moving environments


Why join us

  • Fully remote role with global flexibility

  • Work with live attacker data, not synthetic datasets

  • High-impact, startup-style engineering culture

  • Salary up to £100k
