About the Job

Requirements

Hands-on experience in security operations, incident response, detection engineering, cloud security, vulnerability management, attack-surface management, or a closely related technical security area, including practical experience with Wiz and Tenable or directly comparable cloud-security and vulnerability-management platforms.
Strong log-analysis skills and understanding of alerts, indicators of compromise, authentication activity, network or application behaviour, and evidence needed to investigate a security event.
Experience maintaining a security information and event management platform, preferably Datadog SIEM, including log-source onboarding, parsing, dashboards, alerting, and customised detection rules.
Ability to write and troubleshoot queries, detection rules, or scripts using at least one relevant language or query language, such as Kusto Query Language, SQL, Python, or a comparable tool.
Good understanding of cloud and SaaS security, identity and access management, vulnerability management, web applications, network fundamentals, and secure logging.
Ability to assess whether a finding is a real security issue, a false positive, an expected condition, or a symptom of a wider control weakness.
Coordination and written-communication skills to explain technical findings, request evidence, challenge weak remediation, and escalate missed deadlines.
Ability to improve operational processes through automation while retaining human review for incident command, risk decisions, and formal closure.

Responsibilities

Monitor and investigate security alerts, suspicious activity, vulnerabilities, and incidents across cloud, SaaS, application, and infrastructure environments.
Triage security findings, determine their relevance and severity, identify affected systems, and coordinate practical remediation with product and platform teams.
Drive findings from detection through mitigation, evidence collection, risk acceptance where appropriate, and formal closure; maintain clear ownership, due dates, and escalation paths.
Operate and improve attack-surface management, including asset discovery, domain and service exposure, stale or unmanaged assets, ownership tracking, and remediation follow-up.
Manage vulnerability information from security scanners, cloud-security platforms, and security alerts; correlate duplicate findings and focus on exploitable attack paths and material risk.
Support onboarding and validation of production security logs to central monitoring, including log-source selection, ingestion checks, parsing, coverage evidence, and troubleshooting with product teams.
Operate and improve automated baseline and privileged-activity log review for required monitoring use cases; tune rules and distinguish meaningful deviations from expected administrative or deployment activity.
Maintain the Datadog security information and event management platform, including log-source health, parsing, dashboards, alerting, and coverage; write and tune customised detection rules for GovTech-specific use cases.
Develop and maintain detection logic, queries, dashboards, and alert workflows for cloud and SaaS platforms; reduce noise while preserving visibility of high-value security signals.
Support incident response by establishing timelines, collecting relevant evidence, coordinating containment and recovery actions, documenting decisions, and confirming follow-up actions address the underlying cause.
Build and maintain workflow automation for common incidents and recurring operational tasks, including alert enrichment, team notification, ticket creation, evidence gathering, and status reporting.
Support insider-risk monitoring and related security investigations with appropriate confidentiality, evidence handling, escalation, and stakeholder coordination.
Maintain operational runbooks, detection documentation, log-source inventories, incident records, lessons learned, and response-performance metrics and recurring-gap records.

This role is intended for a hands-on security operations practitioner. Candidates should be comfortable investigating real technical evidence, working with engineers and service owners, and taking ownership of findings through to closure. Experience in a traditional security operations centre is useful but is not the only relevant background.
