Senior Security Engineer, Detection & Response

What You'll Be Doing

  • Build and tune detections across endpoint, identity, SaaS, and cloud using version-controlled, peer-reviewed, and CI/CD practices.
  • Track detection quality through coverage against MITRE ATT&CK, precision, and time-to-detect metrics.
  • Own EMEA-hours incident response including triage, containment, remediation, and writing retrospectives to create systemic fixes.
  • Develop automation to reduce toil in investigations and ensure smooth cross-time-zone handoffs with the US-based team.
  • Define telemetry requirements for new systems before deployment, collaborating with infrastructure and product teams.
  • Proactively threat hunt across the environment, turning hypotheses into new detections or documented coverage.

You Should Have

  • Typically 5–8 years of experience in detection engineering, incident response, or threat hunting with hands-on detection writing and tuning.
  • Proficiency in at least one programming language such as Python or Go, with comfort in writing production-grade detection and automation code.
  • Experience with modern SIEM or detection pipelines like Panther, Elastic, or Splunk, having shipped and tuned detection logic in production.
  • Practical incident response experience with leadership or major roles in triaging and resolving real security incidents.

Nice to Have

  • Experience treating detections as code with CI/CD, peer review, and staged rollouts.
  • Experience defining telemetry contracts for systems before shipping.
  • Strong ability to critically evaluate AI-assisted work through testing, source-checking, and validation rather than blindly trusting outputs.
  • Familiarity with EU data-residency and cross-border data-handling concerns.
  • Experience with fraud or financial-crime detection patterns.
