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.

Job Description

Key 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 through the full lifecycle from detection to 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 attention on exploitable attack paths and material risk.
• Support the 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 (SIEM) platform, including log-source health, parsing, dashboards, alerting and coverage. Write and tune customised detection rules for GovTech-specific security 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 that 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 coordination with relevant stakeholders.

• Maintain operational runbooks, detection documentation, log-source inventories, incident records, lessons learned and metrics for response performance and recurring gaps.
• Hands-on experience in security operations, incident response, detection engineering, cloud security, vulnerability management, attack-surface management or a closely related technical security area. Practical experience with Wiz and Tenable is required, or with 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 the evidence needed to investigate a security event.
• Experience maintaining a security information and event management (SIEM) 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 (KQL), 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.
• Strong coordination and written-communication skills, including the ability to explain technical findings, request evidence, challenge weak remediation and escalate when deadlines are missed.

• Comfort improving operational processes through automation, while retaining human review for incident command, risk decisions and formal closure.
