About The Role

As a Cyber Security Detection Engineer, you will be a cornerstone of our defensive security architecture. This role is designed for a technical expert who excels at building, optimizing, and automating threat detection capabilities within complex, high-scale environments. You will be responsible for ensuring that our security telemetry is not only comprehensive but also actionable and high-performing.

Your primary focus will be the end-to-end lifecycle of security detection: from the engineering of SIEM infrastructure and log orchestration to the development of sophisticated detection logic and automated response playbooks (SOAR). Working at the intersection of Security Operations, Cloud Engineering, and Compliance, you will ensure our defense mechanisms are aligned with industry frameworks such as MITRE ATT&CK and rigorous global standards like ISO27001 and PCI-DSS.
