Job summary

Grab is seeking a senior cybersecurity engineer to join the Insider Threat Detection team in Jakarta. You will design detections across identity, endpoints, cloud services, and data platforms, turning complex threat scenarios into measurable signals and preventive controls.

The role reports to the Lead of Insider Threat Detection and requires hands-on experience with detections, investigations, and AI-enabled security workflows in an on-site capacity.

Qualifications

• At least 5 years of experience in cybersecurity engineering, detection engineering, threat hunting, incident response, insider threat, or enterprise data protection.
• Proficiency in SQL and at least one programming or security-query language such as Python, KQL, or SPL.
• Solid understanding of identity, endpoint, cloud, SaaS, and enterprise data architectures.
• Practical experience investigating user activity across telemetry sources and producing evidence-based findings.
• Familiarity with SIEM, UEBA, DLP, CASB, EDR/XDR, IAM, and cloud-security platforms.
• Hands-on experience building and tuning detections using large-scale security datasets, behavioural baselines, event correlation, anomaly detection, or risk scoring.
• Experience using AI tools and latest technologies to improve security workflows.

Responsibilities

• Design, build and improve behavioural detections for data misuse, unusual access, excessive downloads, unauthorised data movement, credential misuse, privilege abuse, and attempts to bypass security controls.
• Lead complex technical investigations and proactive threat hunts, correlating identity, endpoint, network, cloud, SaaS, application, and data-access telemetry to reconstruct user activity and assess risk.
• Develop queries, scripts, data pipelines, risk-scoring models, and automation to improve telemetry enrichment, alert quality, case triage, investigation speed, and detection coverage.
• Partner with Identity and Access Management, Endpoint Security, Data Governance, and Enterprise Security teams to identify and address gaps across DLP, CASB, SIEM, UEBA, EDR/XDR, cloud, and data-protection controls.
• Develop detection scenarios for Generative AI, large language models, AI agents, and Shadow AI, including sensitive-data exposure, misuse of enterprise AI capabilities, and AI-assisted attempts to evade security controls.
