Senior Security Engineer, Detection and Response

Reference: 46ahxel5odhz1eq7fhte

We are seeking a Senior Security Engineer, Detection and Response to strengthen the capability to identify, investigate and contain cyber threats across a complex technology environment. In this role, you will design, implement and improve detection strategies across cloud, endpoint, identity, network and application layers. You will work closely with security operations, infrastructure, engineering and risk teams to develop resilient monitoring and response processes that reduce attacker dwell time and protect critical systems and data.

Your responsibilities will include developing and tuning detection rules, use cases and correlation logic within security monitoring platforms; analysing alerts and conducting advanced investigations; leading incident response activities from triage through containment, eradication and recovery; and performing proactive threat hunting informed by current tactics, techniques and procedures. You will contribute to incident playbooks, automation and orchestration, improve logging and telemetry coverage, and support post-incident reviews to identify meaningful technical and procedural improvements. You will also help assess emerging threats, validate security controls through testing, and communicate risk, findings and recommended actions to both technical and non-technical stakeholders.

The successful candidate will bring substantial experience in security engineering, detection and response, threat hunting or a closely related discipline. You should have strong knowledge of security monitoring and analysis tools, endpoint and network technologies, cloud security concepts, identity and access management, and common attack frameworks such as MITRE ATT&CK. Experience writing queries or detection logic, scripting with languages such as Python or PowerShell, and automating response workflows is highly desirable. You will be comfortable working independently during high-pressure incidents while also collaborating effectively across teams. Strong analytical, communication and documentation skills are essential, along with a continuous-improvement mindset and a commitment to developing practical, risk-based security solutions.
