Collaborate with SOC, Cyber Defense leadership, Incident Response, and engineering teams to review false positives, reduce alert noise, and address detection coverage gaps
Map detections to critical assets, attacker TTPs, telemetry sources, and incident response runbooks
Ensure critical detections have a clear owner, documentation, and validated testing evidence
Lead security automation initiatives that accelerate investigations while avoiding unsafe autonomous actions

Requirements
Higher education in Computer Science, Information Security, or a related technical field is preferred
5+ years of experience in SOC, Detection Engineering, Threat Detection, or Security Automation
2+ years of hands-on experience in Detection Engineering
1+ year of experience leading or mentoring a team of engineers

Experience defining and tracking Detection Engineering metrics and KPIs (MTTD, MTTR, false-positive rate, and detection coverage)
English - Intermediate+

Will be a plus
Experience in fintech, brokerage, trading platforms, payments, or other regulated financial environments
Experience with cloud-native detection (CNAPP/CSPM) across AWS, GCP, and Azure
Experience with AI/LLM-assisted alert summarization or detection tooling
