The posting

Assurity Trusted Solutions (ATS) is a wholly owned subsidiary of the Government Technology Agency (GovTech). As a Trusted Partner over the last decade. ATS offers a comprehensive suite of products and services ranging from infrastructure and operational services, governance and assurance services as well as managed processes. In a dynamic digital & cyber landscape where trust & collaboration is key, ATS continues to drive mutually beneficial business outcomes through collaboration with GovTech, government agencies and commercial partners to mitigate cyber risks and bolster security postures.

Responsibilities:

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.

Requirements

  • Experience with AWS, Microsoft Azure, Google Cloud, Microsoft 365, Google Workspace or other cloud and SaaS platforms.
  • Experience with Wiz, Tenable, Datadog SIEM, Elastic, Microsoft Sentinel, Chronicle, Splunk, Defender, GuardDuty or comparable cloudsecurity, vulnerability-management, monitoring and security platforms.
  • Experience with incident-response case management, ticketing, security orchestration and automated response workflows.
  • Experience analysing security logs, onboarding log sources, validating coverage, normalising events, tuning detections or maintaining detection-ascode practices.
  • Experience with vulnerability scanners, cloud-security platforms, vulnerability-management workflows and attack-surface management.
  • Relevant certifications such as Security+, CySA+, GCIH, GCDA, SC-200 or equivalent practical experience. Certifications are useful but do not replace investigation ability.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
